Fullstack Developer (f/m/x)

About the role

As a Junior Fullstack Engineer (Freelance), you'll work alongside our engineering team to build features across our platform, from React components and UI to API endpoints and backend logic. You'll get exposure to a modern stack with deep AI integration, learn fast from experienced engineers, and contribute to a product with real users and real impact.

What to expect

• You implement product features end-to-end under the guidance of senior engineers, from React components and UI to API endpoints and backend logic.
• You participate in technical discussions and code reviews, first as a learner, increasingly as a contributor.
• You contribute to our AI-powered features: implementing LLM integrations, working with embeddings, and helping build out RAG patterns.
• You write clean, tested, and well-documented code, and you take ownership of what you ship.
• You work closely with our CTO and senior engineers, take feedback well, and ramp up fast.
• You work with the latest AI tools (e.g. Cursor, Claude Code) and our modern stack.

Where you'll work

This is a fully remote freelance role, open internationally. We hire based on skills and fit, not geography. We do ask for meaningful overlap with our Berlin team's working hours (at least 4 hours per day with CET) so we can actually collaborate.

What you bring

• Relevant experience as a Engineer. We're looking for profiles with a real track record, not fresh graduates. We don't filter by a rigid number of years; we look at your individual experience.
• You know our stack. Required: TypeScript, Next.js, Node.js, React.js, Tailwind CSS. Nice to have: Prisma ORM, Vercel AI SDK, prompt engineering, and experience with vector storage technologies (e.g. Pinecone, Weaviate).
• Strong judgment in design and architecture. You recognize when "good enough" really is good enough, and when a decision will come back to bite you in two years.
• You know your way around AI. Fuxam is AI-native, and that goes double for this role. You work with AI tools when coding every day (Cursor, Claude Code, Copilot, or similar), and you build AI features into the product.
• Quality mindset. You review your own work because you want to deliver your best, not because a task definition tells you to. You document because your future self will thank you. You take code reviews seriously.
• Drive, team fit, and performance. Lots of people can code these days, that alone isn't enough for us. We're looking for people who genuinely want to move things forward, bring their own ideas, take ownership, and deliver results, not just code. You work independently, communicate directly and clearly, give honest technical feedback, and take it the same way.
• Languages: Excellent English; German is a plus but not a must.
• Bonus: Experience with multi-tenancy, SSO/OIDC, accessibility (WCAG/BFSG), or software in the education sector.

What we offer

• Work with substance. Fuxam changes how educational institutions work. Not as a marketing promise, but as concrete relief for the people whose job it is to educate others. Universities, vocational schools, and academies are stuck in a real modernization backlog; what you build has direct impact on the daily lives of teachers, administration, and students.
• A team you can take seriously. Experienced, professionally strong colleagues who support each other without falling into manufactured team spirit. Direct communication, honest feedback, mutual respect. We have a dedicated team-building budget for joint workshops and team events, because personal collaboration also has impact outside of the everyday work.
• We embrace Culture & Growth: Do you want to take responsibility, love challenges, and want to grow with us? Perfect! It's important to us to continuously improve how we work together and to make sure everyone on the team gets to shape it.
