• Work Policy: : Hybrid; fully remote possible for exceptional candidates
• Work Experience: +5 years experience
• Language Requirement: English B2

• 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.

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.
