Senior Full Stack Software Engineer - AI, React, Node.js & TypeScript

• Build production-grade applications with React, Next.js, TypeScript and Node.js - from UI to APIs and services.
• Design AI-native experiences: conversational UIs, agent-driven workflows and natural-language interactions.
• Use AI as an engineering multiplier. Explore, prototype, implement, debug and test faster - while staying firmly in control of architecture, quality and the final result.
• Understand the customer, the business and the problem before deciding what to build.
• Challenge assumptions, simplify complexity and turn ambiguity into products people actually use.
• Shape scalable architectures, APIs and data structures across the stack.
• Collaborate with Product, UX/UI and Engineering to make better decisions together.
• Raise the bar for testing, performance, maintainability and engineering quality.

You’re not here to turn tickets into components. You’re here to decide what should be built - and then build it., * High standards, low ego: We take our work seriously, but not ourselves. Direct feedback, honest collaboration, no drama.

• Stay sharp: Hackathons, conferences, community - we invest in your growth and keep you at the cutting edge.
• And yes - the fundamentals are covered too: 30 days of vacation + Dec 24 & 31 off, Smart Fridays (4 days week possible), mobility (Germany ticket & JobRad), sports & health offerings, mental health support, corporate benefits, RTL+ access, and more.

• Think and work AI-native. You already use AI as part of your engineering workflow and have developed your own approach to getting from idea to production-ready code.
• Bring 5+ years of hands-on full-stack JavaScript experience and a strong track record of shipping real applications.
• Bonus: AWS, Jenkins, Grafana, Graylog, Confluence, Jira, shell scripting.
• Master React, Next.js, TypeScript and Node.js and understand modern web architectures.
• Make confident technical decisions around architecture, performance, scalability and maintainability.
• Build and test production-grade software. Hands-on experience with Jest, Vitest or Node.js testing is essential.
• Work confidently with APIs and data: REST, database design and SQL; GraphQL is a plus.
• Think beyond the code. You’re curious about customers, products and the business and use that context to make better technical decisions.
• Take ownership of outcomes, not just implementation.
• Stay curious about what’s next. Experience with AI-first interfaces, agent workflows or natural-language products is a plus.

Remote in our day-to-day work. On-site when it matters. We work remote by default - focused, efficient, and with full ownership. For larger features, architectural decisions, and real brainstorming sessions, we come together in Berlin - fast, hands-on, and without unnecessary meeting overhead.

We use AI to accelerate - not to replace thinking. We design the system, steer the output, and take responsibility for what we ship. Fast where it makes sense. Careful where it matters.
