Full Stack Engineer

• Own features end to end, by yourself - from the problem through architecture, implementation, release and the fixes that follow, frontend, backend and everything in between; nobody hands you a finished spec and nobody finishes your work for you
• Make the technical decisions, from choosing a library to architecting a new feature, and defend the decision when it is questioned
• Integrate AI into the product, working with our AI services to build dependable systems around probabilistic output
• Build real-time features with WebSocket-based live capabilities where latency is visible to the user
• Ship on desktop and mobile, working on our Electron app (main and renderer architecture, native OS integration, auto-update, offline-first behaviour) and React Native app
• Iterate fast with continuous deployment and short cycles, ensuring design controls and traceable test evidence on the surfaces that fall under EU MDR
• Take initiative creating tickets and implementing them end-to-end

• Genuinely full-stack. Strong React and TypeScript on the front end, and real backend work behind it: API design, data modelling, relational databases, async and background processing. You have built and operated both halves of a feature, not consumed an API someone else wrote
• You have shipped software that real users depend on, and you supported it afterwards. You know what breaks in production and why
• Debugging strength across the whole stack. When something is wrong you find it rather than guess at it
• Real autonomy. You identify what needs doing, decide, and ship. No standup is what keeps you moving
• Empathy for the people who use what you build. Our users are therapists under time pressure, and you are curious enough about their work to build something they actually love
• Clear written English and comfort working async
• React, TypeScript, API design
• Data modelling
• Relational databases
• Async processing, * German. Our users, their documents and our support conversations are in German
• Excellence and Drive are required. But typically > 5 years
• Strong autonomy, very ambitious and driven, curious about the domain

• Technical Skills Required: Full Stack Development, TypeScript, React Native, LLMs, API design, Electron
• Industry: HealthTech/Software-as-a-Service (SaaS)
• Positions Available: 1

Company Mission

They relieve psychotherapists of administrative burdens through intelligent AI assistance, giving them more time for what matters most: working with patients and providing high-quality therapy.

Core Values

Empathy: They develop for people who help others. That’s why they listen and build solutions that make everyday practice noticeably easier instead of complicating it.

Trust: Trust is their foundation. They work uncompromisingly securely, transparently, and reliably-both with their data and within their team., * High degree of creative freedom: End-to-end responsibility for features and architectural decisions in direct collaboration with the CTO and founders.

• Broad technical scope ranging from React/TypeScript to Electron & React Native to LLM integration with real-time WebSocket functionality.
• Practical AI engineering tasks in production systems rather than demo projects, including cost and latency optimization in compliance with the EU MDR.
• Tangible social impact: The software frees up hours each week for therapists, thereby improving psychotherapeutic care.
• A dynamic, fast-growing scale-up that is already the market leader in the DACH region and is pursuing ambitious product roadmaps.
• An attractive package including a copetitive salary, a substantial equity stake, 28 days of vacation, and a flexible hybrid or remote work setup in Berlin-Mitte.

Why Work WIth Them

• Own entire features in a bootstrapped, market-leading HealthTech scale-up-no layers, direct CTO access.
• Ship real AI solutions that save therapists hours weekly-your code impacts mental-health care immediately.
• Competitive salary plus meaningful equity; high autonomy to choose tools & architecture.
• Hybrid Berlin or remote for exceptional engineers; flexible hours & latest equipment.
