Senior Frontend Developer

Senior Frontend Engineer - Web UI / API Integration Client engagement - Financial services domain Role Summary We are looking for a Senior Frontend Engineer to join a domain-focused product team within a large financial services client. You will work inside a mature micro frontend ecosystem where the architectural complexity is abstracted away by tooling, so your day-to-day focus is on delivering well-tested, resilient features that integrate against GraphQL and REST APIs. What you will do Implement features against atomic user stories, inside an SSR-first, independently deployable micro frontend module. Integrate against GraphQL and REST APIs, handling partial data, schema-level errors, transport errors, and the difference between retryable and terminal failures. Aggregate data across multiple resources utilizing built-in Javascript features, and surface it through well-typed client state. Own the server-state vs client-state boundary, TanStack Query for server state (caching, refetch, dedup, lifecycle), Redux for cross-module and derived UI state. Deliver features with 100% code coverage using Jest and React Testing Library, and know when each tool is the right choice. Participate in Agile Scrum ceremonies, branch, and PR hygiene via Git, and code review with a quality-first mindset. Required Skills Strong React 18+ experience: hooks, suspense, concurrent rendering implications, component composition over inheritance. Total type safety in TypeScript: discriminated unions, generics, mapped and conditional types, type narrowing. Comfortable modeling API responses, error states, and domain entities as precise types, not just as interfaces with optional fields. Redux (Redux Toolkit) for client and cross-module state, slices, selectors, memoization, normalized state shape. TanStack Query for server state, staleTime vs gcTime, query keys, refetch strategies, optimistic updates with rollback, error and loading lifecycle. Articulates clearly where the boundary sits between the two and does not put server responses in Redux by default. GraphQL consumption: reading schemas, understanding partial data plus errors arrays, fragment design, query co-location. REST integration with explicit handling of HTTP semantics (idempotency, status code classes, retry policy, timeouts). Defensive integration: input validation, output validation against contract, and explicit failure modes for every external call. Comfort merging, reducing, filtering, and shaping data from multiple sources before it reaches the UI layer. React Testing Library as the default for component and integration tests, user-facing behavior, not implementation details. Jest for unit tests, utilities, reducers, selectors, and the fragments RTL is not the right tool for. Comfortable working towards 100% code coverage as a sustained standard, not a one-time push. Parrot or equivalent for mocking the API boundary in tests. Agile Scrum: estimation, sprint commitment, breaking work into atomic stories or tasks. Git: clean history, focused PRs, meaningful messages, follow the git linter, conflict resolution under pressure. Code Review discipline: Rejects PRs lacking error handling, type safety, or test coverage, including your own. Fullstack Awareness You don’t need to be a backend engineer, but you should not think of the API as a blackbox. Understand why a N+1 problem in GraphQL resolver is a frontend concern (page load tail latency). Reads a schema and infers what the upstream cost of a query likely looks like. Knows enough about HTTP, auth boundaries, and idempotency to write integration code that doesn’t cause downstream incidents. Can converse with backend engineers about contract design rather than just consuming what they hand over. What you will walk into… The client operates a SSR-first micro frontend architecture. Modules are independently deployable, isolated at runtime, and composed at request time. The platform abstracts the complexity, you work inside a single workspace with one CLI, one bundler, one runner. You will not be expected to know the internals of the platform on day one. You will be expected to respect its boundaries and not work around them. Seniority Expectation This is a Senior individual contributor role. You will own your stories end to end, including their failure modes. You will not be designing the platform, but you will be expected to push back (with evidence) when a story written would introduce fragility, leaky abstractions, or untested edges. Logistics Engagement: Long-term staffing with a financial service client. Methodology: Agile Scrum, two-week sprints typically. Tooling: React, TypeScript, Redux, Redux Toolkit, TanStack Query, GraphQL, REST, Apollo Client, RTL, Jest, Figma, Git. Coverage requirements: 100% on new code

Senior Frontend Developer

Senior Frontend Engineer - Web UI / API Integration Client engagement - Financial services domain Role Summary We are looking for a Senior Frontend Engineer to join a domain-focused product team within a large financial services client. You will work inside a mature micro frontend ecosystem where the architectural complexity is abstracted away by tooling, so your day-to-day focus is on delivering well-tested, resilient features that integrate against GraphQL and REST APIs. What you will do Implement features against atomic user stories, inside an SSR-first, independently deployable micro frontend module. Integrate against GraphQL and REST APIs, handling partial data, schema-level errors, transport errors, and the difference between retryable and terminal failures. Aggregate data across multiple resources utilizing built-in Javascript features, and surface it through well-typed client state. Own the server-state vs client-state boundary, TanStack Query for server state (caching, refetch, dedup, lifecycle), Redux for cross-module and derived UI state. Deliver features with 100% code coverage using Jest and React Testing Library, and know when each tool is the right choice. Participate in Agile Scrum ceremonies, branch, and PR hygiene via Git, and code review with a quality-first mindset. Required Skills Strong React 18+ experience: hooks, suspense, concurrent rendering implications, component composition over inheritance. Total type safety in TypeScript: discriminated unions, generics, mapped and conditional types, type narrowing. Comfortable modeling API responses, error states, and domain entities as precise types, not just as interfaces with optional fields. Redux (Redux Toolkit) for client and cross-module state, slices, selectors, memoization, normalized state shape. TanStack Query for server state, staleTime vs gcTime, query keys, refetch strategies, optimistic updates with rollback, error and loading lifecycle. Articulates clearly where the boundary sits between the two and does not put server responses in Redux by default. GraphQL consumption: reading schemas, understanding partial data plus errors arrays, fragment design, query co-location. REST integration with explicit handling of HTTP semantics (idempotency, status code classes, retry policy, timeouts). Defensive integration: input validation, output validation against contract, and explicit failure modes for every external call. Comfort merging, reducing, filtering, and shaping data from multiple sources before it reaches the UI layer. React Testing Library as the default for component and integration tests, user-facing behavior, not implementation details. Jest for unit tests, utilities, reducers, selectors, and the fragments RTL is not the right tool for. Comfortable working towards 100% code coverage as a sustained standard, not a one-time push. Parrot or equivalent for mocking the API boundary in tests. Agile Scrum: estimation, sprint commitment, breaking work into atomic stories or tasks. Git: clean history, focused PRs, meaningful messages, follow the git linter, conflict resolution under pressure. Code Review discipline: Rejects PRs lacking error handling, type safety, or test coverage, including your own. Fullstack Awareness You don’t need to be a backend engineer, but you should not think of the API as a blackbox. Understand why a N+1 problem in GraphQL resolver is a frontend concern (page load tail latency). Reads a schema and infers what the upstream cost of a query likely looks like. Knows enough about HTTP, auth boundaries, and idempotency to write integration code that doesn’t cause downstream incidents. Can converse with backend engineers about contract design rather than just consuming what they hand over. What you will walk into… The client operates a SSR-first micro frontend architecture. Modules are independently deployable, isolated at runtime, and composed at request time. The platform abstracts the complexity, you work inside a single workspace with one CLI, one bundler, one runner. You will not be expected to know the internals of the platform on day one. You will be expected to respect its boundaries and not work around them. Seniority Expectation This is a Senior individual contributor role. You will own your stories end to end, including their failure modes. You will not be designing the platform, but you will be expected to push back (with evidence) when a story written would introduce fragility, leaky abstractions, or untested edges. Logistics Engagement: Long-term staffing with a financial service client. Methodology: Agile Scrum, two-week sprints typically. Tooling: React, TypeScript, Redux, Redux Toolkit, TanStack Query, GraphQL, REST, Apollo Client, RTL, Jest, Figma, Git. Coverage requirements: 100% on new code

Senior Blockchain Security Developer (Canton)

From $35/yr

About Us OpenZeppelin is the security standard onchain finance is built on. Founded in 2015, our mission is to accelerate the world's transition to an open financial system, built on open standards and secured by rigorous research. Our open-source Contract Libraries have facilitated over $35 trillion in onchain value and are used by 10 of the top 10 tokenized money market funds and 9 of the top 10 stablecoins by market cap. We combine AI-native security tooling with deep research and a decade of audit expertise to support leading institutions and crypto-native teams shaping the next generation of digital assets like DTCC, Fidelity, Coinbase, Uniswap, Aave, the Ethereum Foundation, and many more across the full secure development lifecycle. Please note: Always refer to OpenZeppelin's official job page for the most accurate information about our open roles, as we have seen multiple third party job sites posting inaccurate information. The Secure Development team ❤️ OpenZeppelin is the security partner of choice for the most important protocols in Web3. Our Secure Development team sits at the intersection of building and breaking: we design, implement, and harden production-grade libraries and smart contracts for leading projects across EVM, Starknet, Stellar/Soroban, Arbitrum Stylus, Aptos, and beyond, often as an embedded extension of the client's engineering team. We work the way the rest of the industry will five years from now. Every developer on the team is a fully AI-native engineer, supported by outstanding internal AI tooling built for every phase of secure development. Developers own their workstreams end-to-end — agents amplify their effectiveness, and peers, security researchers, and external auditors provide rigorous review on every piece of work that ships. The Canton Network engagement This role joins us at the start of a 24-month, multi-million-dollar commitment to build the open-source DeFi foundations of the world's most institutional blockchain, approved by the Canton Foundation. The scope: * 8 production-ready Reference Implementations. Privacy-preserving DEX, lending protocol, cross-chain stablecoin settlement, confidential auction launchpad, and four more defined in year two. End-to-end blueprints that other teams will fork. * The OpenZeppelin Contracts Library for Daml. The audited foundation Canton developers will import — vaults, hooks, RBAC, credentials, modular multi-sig accounts, standardized messaging gateway, DeFi math, staking, vesting, auctions, more. The same role our Solidity library plays today, on Canton. * Canton standards implementation. Audited Daml implementations of CIP-56 (Token Standard), CIP-86 (ERC-20 Compatible Interface), CIP-103 (dApp Standard), and CIP-104 (Traffic-Based App Rewards) — designed to interoperate cleanly with the broader Splice ecosystem and with ChainSafe's CIP-86 middleware. * 55 researcher-weeks of dedicated security capacity. Smart-contract audits, full-stack reviews, pen tests — amplified by OpenZeppelin's AI security agent in the workflow. Every release ships with a published audit report. * AI-native developer experience for a new ecosystem. Contracts Wizard, UI Builder, MCP Server, Claude Plugin, AI Skills — all built for Canton, all AI-native end-to-end. You'll help define how AI-native engineering looks on a non-EVM stack. You'll work alongside Digital Asset, the Canton Foundation, and ChainSafe. The deliverables become the standard others build on. The work is public; the impact is measurable; the partners are the institutions reshaping how capital moves. Canton is your first focus, but you'll keep contributing across the broader Secure Development portfolio as the work demands. Within this, you will: * Own the development of the OpenZeppelin Contracts Library for Daml end-to-end: vaults, hooks, RBAC, credentials, messaging gateway, accounts, and more. The audited primitives Canton developers will import. * Lead the technical design and implementation of the year-1 Reference Implementations: privacy-preserving DEX, lending protocol, cross-chain stablecoin settlement, and confidential auction launchpad. * Implement and shepherd the OZ Daml versions of CIP-56, CIP-86, CIP-103, and CIP-104. Coordinate with Digital Asset on spec evolution and with ChainSafe on middleware alignment. * Run client-facing roadmap, design, and milestone discussions with Digital Asset, the Canton Foundation, and ChainSafe. * Collaborate with OpenZeppelin's auditors and security researchers on threat models, audit prep, and full-stack reviews for every Reference Implementation. * Use AI systems as core daily tools. Extend them: build agents, skills, and workflows that compound the team's leverage on the Canton engagement and beyond. * Apply AI directly to security work and share what works back to the team: audit assistance, invariant generation, spec analysis, fuzzing harnesses, custom evals * Contribute developer-experience and security feedback upstream into the Canton protocol, Splice, the Daml SDK, and the Splice Wallet Kernel. * Conduct open-ended research around privacy-preserving DeFi, multi-party authorization patterns, and Canton-specific primitives; you'll have time to publish and contribute back to OpenZeppelin's body of knowledge. Location OpenZeppelin is a fully remote organization, however candidates for this position must be located within UTC-8 to UTC+3 time zones to be considered. You have * Production Daml fluency. You have shipped non-trivial Daml in production. You understand templates, choices, controllers/observers/signatories, multi-party authorization, sub-transaction views, and propose/accept patterns as first-class primitives. Running an SV, contributing to Splice internals, governance, or Canton Coin tokenomics. * 3+ years of experience in UTXO-based protocol development. You can reason about Canton's privacy boundaries the way an EVM developer reasons about storage slots. Prior production work in a privacy-preserving or UTXO-based architecture (Canton, Cardano, Midnight, Zcash, Aleo, Mina, or similar) is expected. * 3+ years of experience on DeFi engineering in production. you have shipped non-trivial DeFi primitives in production: AMMs, vaults (ERC-4626 or equivalent), lending protocols, cross-chain settlement. You understand the security pitfalls of each. * A security-first mindset. this is non-negotiable. You think adversarially about every line of code you write, and you have demonstrable experience either auditing, breaking, or hardening production systems — published threat models, audit reports, responsible disclosures, or equivalent output. * Library / SDK API design taste. You've built reusable, import-first developer libraries, not just applications. You have opinions on extensibility patterns (hooks, modular components, override points) and on what makes an audited primitive pleasant to consume. * Cross-chain interoperability exposure. Production work with at least one major cross-chain messaging protocol (Chainlink CCIP, LayerZero, Wormhole, Axelar, or similar). * Institutional / compliance design fluency: You can design with credential gates, multi-party attestation, custody flows, and compliance hooks as native constraints. * An AI-native workflow. Claude Code, Cursor, or equivalent is your daily driver. You have measurable productivity gains to show for it and clear opinions on how to use these tools well. You have shipped at least one non-trivial AI-powered tool, agent, or automation pipeline in production using the Anthropic SDK, MCP, custom evals, or comparable. * Experience applying AI to security work: You've already used AI as a serious instrument in security workflows: audit assistance, vulnerability research, fuzzing, invariant or spec analysis, static-analysis augmentation, or similar. * Fluency in client-facing communication (English). * Autonomy and proactivity. Nice to have * Cryptography or financial-engineering background. Privacy-preserving DeFi rewards both. * Institutional finance background. Capital-markets microstructure, custody, compliance flows, RWA tokenization, settlement. * Hands-on experience with non-EVM ecosystems. Starknet, Stellar/Soroban, Arbitrum Stylus, Aptos, Move-based chains. * Open-source contributions to widely-used libraries in the smart-contract or AI-tooling space. Logistics Our interview process is designed to be fast (we target ~30 days from first call to offer) while still giving both sides a clear "yes." The full process consists of: * Recruiter interview (30-45 minutes) * Manager interview (60 minutes) * Peer interview (45 minutes) * Paid technical work trial Please let us know if you require any accommodations for the interview process, and we’ll do our best to provide assistance.
