Senior Product Design Engineer Jobs

Senior Product Design Engineer

At Rohlik Group, we are building the future of e-grocery for over a million active customers across the Czech Republic, Germany, Austria, Hungary, and Romania. We own our entire technology stack — from storefronts and apps to automated fulfillment centers and last-mile logistics. Within the Customer Experience (CUEX) domain, we own every touchpoint a customer interacts with, from the homepage to checkout and real-time order tracking across web, iOS, and Android. Our five storefronts run on a single product spine with localized content, pricing, and brand layers. We operate as a deliberately tight-knit, high-performing team where a Product Owner, Engineering Manager, Tech Lead, two Product Designers, and a dedicated full-stack engineering team ship fast, iterate constantly, and take full ownership of the end-to-end user journey. Most interface failures in e-commerce aren’t layout issues — they are communication problems: what is said, in what order, and on which screen. As Senior Product Design Engineer, you will own the end-to-end design of all customer-facing surfaces across five markets. You will also manage our design system, Maia (our AI shopping assistant), and provide the design guidance that powers our automated coding workflows. Why this role is exciting High-impact Group scope: Design every customer-facing touchpoint across web, iOS, and Android for five international markets, impacting millions of orders. True end-to-end ownership: Lead the complete lifecycle of product design — from initial problem definition and customer research to shipped A/B tests and real-world performance analysis. AI-first execution: Rohlik is an AI-first company. You’ll own the interface design for Maia, our AI shopping assistant, and build the structured design system guidance used by AI coding agents to generate on-brand code without hand-coding interfaces. Direct customer engagement: Lead user research and usability testing sessions directly with real shoppers, rather than commissioning external agencies or receiving filtered insights. High accountability, low overhead: Work in a small, autonomous team where design decisions move straight to production and work that doesn't deliver measured impact is honestly reverted. What you will own and deliver Customer Surfaces: Own the end-to-end design and UX strategy across web, iOS, and Android for all core journey stages: homepage, search & browse, product pages, basket, slot selection, checkout, and order tracking. Design System as a Product: Own component architecture, design tokens, patterns, and documentation, ensuring our coding agents have precise design guidance to generate accurate interfaces. AI Experience Design: Define the interaction patterns for Maia (our AI shopping assistant), governing when it intervenes, how it presents information, and how it hands over to human support. Experimentation & Analysis: Drive hypotheses, prototype rapidly, and evaluate A/B test results objectively — scaling successful experiments and sunsetting features that miss target performance. Direct User Research: Conduct qualitative interviews, usability tests, and field research directly with customers to continuously uncover friction points. Cross-Functional Partnership: Collaborate closely with the Product Owner, Engineering Manager, Tech Lead, and your peer product designer, while providing design input to Commercial, Marketing, and Operations. What we are looking for 5+ years of experience designing consumer-facing digital products with a strong portfolio of shipped work across both web and native mobile (iOS and Android). Advanced Figma & Design System expertise: Deep, hands-on experience building, scaling, and architecting multi-platform design systems at the token and component level. Data-fluent mindset: Ability to read and rigorously interpret A/B testing data, distinguishing genuine impact from vanity metrics. Fluency with AI tooling: Practical experience integrating AI tools into modern design, prototyping, and design system workflows, along with a clear view of where conversational AI adds real interface value. User research expertise: Demonstrated experience designing, running, and analyzing qualitative usability sessions directly with end users. Strong product reasoning: Excellent communication skills in English (C1 level or above), with the ability to articulate the strategic and behavioral rationale behind design decisions. Nice-to-haves: Experience designing production-grade AI or assistant-driven interfaces. Experience contributing directly to code at the component or token level. Background in e-commerce, quick-commerce, online grocery, or last-mile delivery. First-hand familiarity with how German customers shop. Fluency in German or Czech. What’s in it for you Fair pay, transparent, stable compensation A strong fixed salary with clear rules. No bonus politics. Great work is rewarded openly and fairly. Good food options, fresh, every day Enjoy subsidised meals/fresh food options in the office and regular refreshments like drinks, fruit, and snacks that keep you energized. Life beyond work, hybrid work & real flexibility Three days in the office and the rest where it works best for you. Take time off when you need it with paid vacation days above statutory and flexible scheduling. Grow with Knuspr every day - we move fast, and so can you. Learn, experiment, and take ownership from day one. Every challenge is a chance to grow. Recognition & community - Your impact is seen and appreciated. You can celebrate colleagues through Bonusly peer-recognition credits and feel supported by a team that works hard and wins together. Health & wellbeing - Access to our UNIQA private insurance option and supportive wellbeing culture, keeping you healthy inside and outside of work.

Design Engineer, Product (Senior/Staff) (d/f/m)

From $500/yr

Personio's intelligent HR platform helps small and medium-sized organizations unlock the power of people by making complicated, time-consuming tasks simple and efficient. Our team of 1,500 Personios is building user-friendly products that delight our 15,000+ customers and their 1.5 million employees. Ready to make an impact from day one? This role requires 2 days per week in the office and is based in Munich/Berlin/London. As a Design Engineer at Personio, you will sit at the intersection of design craft and technical execution, bridging the gap between how we imagine our product and how it gets built. You will be a key force in elevating the quality, consistency, and velocity of our product experiences, working as part of our Design Infrastructure team, while also working across product teams on highest-priority initiatives. You will build the UI components, infrastructure and systems that empowers designers to work closer to code with consistency, contribute to high-priority product experiences that touch every customer, and help create AI-powered tooling that automates repetitive front-end work. As an early member of a newly-formalized discipline at Personio, you will help define what great Design Engineering looks like — and set the bar for those who follow. What You'll Do * Steward and improve the design system by building and maintaining high-quality, accessible, and performant components and patterns that are used consistently across Personio’s product surfaces. * Uplevel cohesion in the product by spotting gaps in consistency across the product, connecting disparate projects, and building reusable patterns and frameworks that scale. * Contribute to high-priority product features by embedding with product teams to deliver UX features and systems that benefit a wide reach of customers. * Collaborate across disciplines — maintaining a close relationship with both design and engineering to stay aligned on platform priorities, developer experience, and the evolving standards that govern design–engineering handoff. * Contribute to our Product \& Technology culture by bringing technical perspective into design conversations, and design perspective to engineering, mentoring designers on front-end concepts, and helping the org think more fluently about code and design together. * Build AI-powered design tooling and workflows that move designers closer to code through high fidelity prototyping and live production edits. * Help define and evolve the Design Engineering discipline at Personio — contributing to career expectations, playbooks, and processes as this practice matures. What You Need To Succeed * Technical proficiency in front-end development (React, Typescript, CSS) combined with strong UX sensibility and product instincts. Should have familiarity with NextJs, monorepos, UI testing, performance considerations and accessibility. Preference for experience with Vercel, Microfrontends and Motion. * Hands-on experience with design systems, including building and scaling component libraries, tokens, and patterns adopted by multiple teams. * Comfort with AI-assisted design and prototyping tools (e.g., Cursor, Claude), and a track record of using these to accelerate design-to-code workflows. Preference for familiarity of the Claude ecosystem and agentic development workflows. * Experience creating reusable frameworks, tooling, or processes that improve how design and engineering teams work together and that are adopted beyond their original context. * Demonstrated ability to collaborate across functions — working fluidly with designers, product managers, and engineers, and communicating at the intersection of both disciplines. * An eye for craft and consistency, with the drive to proactively identify quality gaps and take initiative to address them across the product. * Comfort operating in ambiguity, with the self-direction to define your own scope, navigate undefined spaces, and bring clarity to cross-functional challenges. * AI Fluency: You have hands-on experience using AI to improve your workflow, and the sound judgment to know exactly when to rely on it and when to step in yourself. Why Personio Personio is an equal opportunities employer, committed to building an integrative culture where everyone feels welcomed and supported. We embrace uniqueness and understand that our diverse, values-driven culture makes us stronger. We are proud to have an inclusive workplace environment that will foster your development no matter your gender, civil status, family status, sexual orientation, religion, age, disability, education level, or race. At Personio, we value in-person collaboration while also offering flexibility. This role is office-based, with 2 days per week required in your contracted office location. The remaining days can be worked from home or in the office if you prefer. In addition, you’ll have 20 Flex Days per year to work remotely from other locations. Aside from our people, culture, and mission, check out some of the other benefits that make Personio a great place to work: * Receive a competitive reward package – reevaluated each year – that includes salary, benefits, and pre-IPO equity * Enjoy 28 days of paid vacation, plus an additional day after 2 and 4 years * Make an impact on the environment and society with 1 (fully paid) Impact Day * Receive generous family leave, child support, mental health support (including 24 sessions per year with Oli for yourself and 10 sessions for a significant other), and sabbatical opportunities * We enjoy gathering for meals, cultural initiatives, and events like local Summer Sessions and year-end celebrations. There's also healthy snacks, drinks, and a weekly catered lunch.
