Senior AI Enabled Product Engineer — Frontend Focus (fmd)

You will own the part of that neighbors actually see and touch. 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. You will work with React and TypeScript on the frontend. Ruby on Rails on the backend PostgreSQL and AWS.

Concretely you will:

• 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 wont move the metric its meant to move say so early.

• 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 clientserver boundary. Shape the APIs your screens depend on; make deliberate choices about data fetching caching loading and error states; and understand whats happening on the network.

• 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.

• 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.

• Strong React in production: component design state management rendering behaviour
• A real grasp of clientserver 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

• Hybrid work model combining office and remote days
• A meaningful job were 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 foundation
• Responsibility and great opportunities to actively contribute
• Your SpenditCard youll 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.
