Jobbeschreibung

We build digital products people love to use: mobile apps, websites and the automations that power them. AI is changing both how these products are built and what they can do. We're looking for an engineer who builds with care, and sees projects through from the first client conversation to production. Sound like you? Then we'd love to meet you!

What you'll do

• Consult our clients in person. Meet them in Berlin, understand their business, and turn their ideas into concrete technical concepts

• Shape projects from the start. Scope and estimate work, contribute to proposals, and build pitch MVPs that show what's possible

• Own the architecture. Design solutions that fit each client

• Build products people love to use. Develop mobile apps and websites with a high bar for UX, performance and accessibility

• Build AI into real products. Ship LLM-powered features, RAG-based knowledge systems and agentic workflows into production apps

• Run what you build. Deploy, monitor and maintain the systems you deliver

• Work AI-natively every day. Use AI coding agents like Claude Code or GitHub Copilot as a natural part of how you deliver

• Share what you learn. Pass on practices and lessons learned to the team

• Get certified with us. Become a Claude Certified Architect – Foundations as part of our Claude Partner Network membership

What we're looking for

• A university degree in Computer Science, Software Engineering, or a related field

• 3+ years of professional experience in software development, ideally including client or agency work

• Solid TypeScript experience with React Native (Expo) or React (Next.js) and Node.js

• First experience shipping LLM-powered features with AI frameworks such as Vercel AI SDK or Claude Agent SDK

• Experience deploying and running applications in production

• Ideally working knowledge of how the GDPR and the EU AI Act shape the design of AI features, such as data handling, consent, transparency and risk classification

• Product thinking: you think in user problems and business outcomes, not tickets. You question whether a feature is worth building before you build it.

• A sharp eye for quality: you spot UX inconsistencies, performance bottlenecks and accessibility issues before users do, and you know how to fix them

• Strong communication skills: you can explain technical trade-offs clearly to clients and non-technical stakeholders

• Organized and reliable, with an eye for detail and a sense of ownership

• Fluent in English (written and spoken) and German (at least B2)

• Based in or near Berlin and able to meet clients and the team on-site whenever projects need it

What we're offering

• A dynamic, motivated and international team. Our company language is English!

• Flexible working hours and hybrid work: from home or in our modern office in Berlin Schöneberg, on-site whenever client meetings call for it

• Monthly benefits such as a subsidized membership at Urban Sports Club, a monthly shopping voucher or JobRad

• Flat hierarchies and daily opportunities to learn, grow and develop

• Freely usable budget for your home office equipment

• Vibrant team culture with regular events like our summer and winter party

• An inviting and structured onboarding process on‑site in Berlin with a delicious team lunch
