Darum lohnt es sich

This is a frontend-focused role on a full-stack product team: your depth is in the browser and on mobile web, and you follow a feature all the way through the API and into production.

Your profile • Strong React in production: component design, state management, rendering behaviour • A real grasp of client–server architecture: how the browser and the backend actually talk, what that costs, and how it fails • Craft in the fundamentals: modern CSS and layout, semantic HTML, accessibility, web performance, responsive and mobile-first work • Solid command of TypeScript • Experience building or maintaining a design system, or at least a clear opinion about what makes one work • Comfortable owning outcomes, working day to day with non-engineers • Uses AI deliberately as leverage: directs and reviews generated code to production quality • A maker: ships, validates, then refines on what the evidence shows • Cares that the thing works for the person using it, on their phone, on their network • A plus: enough backend familiarity (Ruby, or any server-side language) to change an endpoint yourself • A plus: data-informed product work, with decisions grounded in data • English skills for working in our international team; German is a plus What we offer • Hybrid work model combining office and remote days • A meaningful job – we’re creating a great product with real added value for the community • Work in a cheerful and experienced team that exchanges ideas and learns from each other • Insights into the entire work process of our social startup and the nebenan.de foundation • Responsibility and great opportunities to actively contribute • Your nebenan.de SpenditCard – you’ll receive an additional income of 35 Euros per month, which you can use for things of your choice • 30 days of vacation per year – we also offer the possibility of workation models and a sabbatical • A workplace in Berlin-Kreuzberg and regular events like yoga or Lunch & Learn sessions.

You will work with React and TypeScript on the frontend. Ruby on Rails on the backend, PostgreSQL, and AWS. Concretely, you will: Own your product area • Own a product area end to end. From prototype through production to iteration, mobile-first.

You decide from usage data what to improve next and keep the area healthy on an ongoing basis. • Run what you build. Set and meet performance and reliability targets for your area, instrument before shipping, and handle incidents in your own work. • Challenge the plan.

You work with a product lead who owns the outcome and a product analyst who designs and validates experiments. If a piece of work won't move the metric it's meant to move, say so early. Build the interface • Build React features are accessible, fast, and consistent with our design system. • Own and extend the design system.

Components, tokens, and patterns that other engineers reuse. You push generic work into shared components early. • Work across the client–server boundary. Shape the APIs your screens depend on; make deliberate choices about data fetching, caching, loading, and error states; and understand what's happening on the network.

Work with AI and evidence • Direct AI and be accountable for what it writes. You set intent, review what comes back, and own everything that ships under your name. • Replace manual QA with evidence. Automated tests, visual regression, and instrumentation ground your confidence in data. What this role is not • Not a ticket taker.

You own working software in production, not merged pull requests. • Not pixel-pushing behind a designer. Design and validation of the experience sit with product and design; building it into production software and pushing back on it are yours. • Not frontend-only in practice. Depth in the frontend, contribution across the stack.
