Frontend Engineer — React & Geospatial Applications (m/f/d)

**Build web applications that make complex satellite and geospatial data actionable for political, strategic, and tactical decision\-making** At TerraLens, a bootstrapped and profitable spin\-off of the German Aerospace Center (DLR), you will work on modern React applications for satellite imagery, geospatial data visualization, and human\-in\-the\-loop analysis workflows. You will help build the user\-facing software that allows analysts and decision\-makers to search, process, visualize, and understand complex Earth observation data. This is a hands\-on frontend engineering role for someone who enjoys building substantial client\-side applications, designing clean component APIs, working with maps and geospatial visualization, and turning complex workflows into reliable and intuitive user interfaces. **Role Highlights** * **Location:** Germany; Munich area preferred, remote work possible * **Type:** Full\-time * **Seniority:** Mid to senior level; ideally 3\+ years of relevant frontend engineering experience * **Language:** Excellent English required; good German highly valued * **Compensation:** Competitive salary package, tailored to experience and impact **About TerraLens** TerraLens is a fast\-growing spin\-off of the German Aerospace Center (DLR). We build software that transforms large volumes of Earth observation data into actionable intelligence to support political, strategic, and tactical decision\-making. Our team brings over 20 years of experience in the analysis of Synthetic Aperture Radar (SAR) satellite data, and we are expanding TerraLens to integrate additional data sources and make complex geospatial information easier to search, process, visualize, and analyze. Our software is used operationally in the user segment of SAR satellite missions, supporting human\-in\-the\-loop analysis workflows that require reliability, high\-throughput data processing, and controlled operation in demanding on\-premise and air\-gapped environments. We are bootstrapped, profitable, and growing organically, allowing us to focus on long\-term product quality, real customer value, and sustainable engineering. **The Role** In this role, you will help build and maintain the web applications and frontend libraries that make complex satellite and geospatial data usable for analysts and decision\-makers. This is not a marketing website or generic dashboard role: you will work on data\-heavy, map\-based applications used in operational environments. You will build modern client\-side React and TypeScript applications, develop reusable UI and visualization components, integrate typed APIs, and collaborate closely with backend, geospatial, AI/ML, and domain experts to turn complex analysis workflows into reliable software. Depending on your experience and interests, the role can grow into broader ownership of frontend architecture, shared UI libraries, geospatial visualization components, and technical leadership of user\-facing product development. **What You Will Work On** **Frontend applications for operational geospatial workflows** * Build and maintain modern client\-side React and TypeScript applications for satellite imagery and geospatial analysis * Develop data\-heavy user interfaces for search, visualization, analysis, and human\-in\-the\-loop workflows * Build map\-based interfaces involving raster and vector layers, large imagery, 3D model overlays, and other geospatial visualization components **Turning complex data workflows into usable software** * Collaborate with domain experts and backend, geospatial, AI/ML, and SAR engineers to turn complex operational workflows into intuitive user\-facing applications * Contribute to frontend architecture, reusable UI components, usability, and long\-term maintainability * Improve frontend performance and support deployment in on\-premise and customer\-hosted environments **What We Are Looking For** **Must Have** * 3\+ years of professional frontend engineering experience * Strong experience building production React and TypeScript applications * Good understanding of component architecture, hooks, state management, and API integration * Experience building complex, data\-heavy user interfaces * Solid CSS skills and attention to layout, usability, and interaction details * Experience with modern frontend tooling, build workflows, and TypeScript\-based development * Able to build maintainable, high\-performance frontend code and debug issues across browser, API, and build workflows * Excellent written and spoken English **Nice To Have** * Experience with geospatial, map\-based, or data visualization applications, including tools or concepts such as deck.gl, WebGL, raster/vector layers, GeoJSON, large images, or 3D views * Experience with frontend state and server\-state management libraries such as Zustand, TanStack Query, or similar * Experience writing and maintaining frontend tests with tools such as Vitest, Playwright, or similar * Experience building reusable UI components, internal component libraries, or production\-quality UI from Figma designs * Experience generating TypeScript API clients from OpenAPI specs, for example with Orval * Familiarity with user authentication flows, Docker\-based frontend deployment, or GitLab CI/CD * Familiarity with satellite imagery, GIS, remote sensing, or other geospatial data workflows * Good German language skills * Based in or near Munich, or willing to travel to Munich occasionally **Why Join TerraLens?** * Work on mission\-critical software that turns satellite imagery into actionable intelligence for supporting political, strategic, and tactical decision\-making * Join a bootstrapped, profitable company growing through real customer demand * Build user\-facing applications for complex satellite imagery, geospatial data, and operational analysis workflows * Take real ownership of web applications, UI libraries, map visualization, and frontend architecture * Collaborate across SAR and other Earth observation data, AI/ML, backend systems, and geospatial software * Work in a small, experienced team with room for broader technical ownership as we grow **Compensation \& Benefits** We offer a competitive compensation package tailored to experience and impact, including a benefits program with offers such as Wellpass membership and Deutschlandticket. **How To Apply** Please send your CV, LinkedIn or GitHub profile, and a short note about frontend applications you have built or maintained. We are especially interested in examples involving React and TypeScript, complex user interfaces, map\-based or geospatial applications, data visualization, API\-heavy applications, design systems, testing, frontend deployment workflows, or user\-facing software for technical or operational domains.
