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.
Quality: They deliver professional precision instead of gimmicks. Their AI has to stand up to everyday therapeutic use, which is why they focus on technical excellence with real added value.
Tasks
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
Requirements
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
Debugging
LLM application engineering: evaluation, prompt pipelines, agent tooling, latency and cost optimisation
Electron or another desktop platform, including distribution, code signing and auto-update
React Native, and experience publishing to the App Store and Play Store
Audio processing, transcription or other real-time media
Healthcare, GDPR-heavy or other regulated environments
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
Benefits
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.
