Flutter & Node.js Fullstack Engineer (f/m/d) - Fully Remote

Beyond the core product we're building new and adjacent products, including ones with AI capabilities. If working with LLMs excites you, there's real room to shape that. If it doesn't, that's fine too.

How the role works

You won't get finished designs and implementation specs to execute. You'll get problems, context, and user needs and the freedom to figure out the best solution. That's deliberate: it's where the creativity and the ownership live. It also means the job asks you to think about what to build, not only how .

Today our CTO is hands-on in the codebase, supported by a part-time engineer. You'd join as the next full-time engineer on a small team where your decisions carry real weight.

Day to day

• Frontend: evolve our Flutter app (iOS & Android), with a strong focus on good UX and usability for people aged 50+
• Backend: design and build our Node.js APIs and services for new features
• Product: work closely with our medical and product colleagues: your voice matters in what we build and how
• Quality: help us keep code review, testing, and engineering standards at the level a regulated medical product demands
• Optional: if DevOps interests you, there's room to shape our cloud infrastructure, CI/CD, and deployment but it isn't the core of the job

Requirements

What you bring

• 3+ years of professional software engineering experience, and we care far more about what you've actually shipped than about the number. Show us something you built
• Flutter/Dart skills, or a proven ability to ramp up fast (e.g. coming from React Native or native mobile)
• Working knowledge of Node.js and building APIs, you don't have to be equally strong on both ends, but you can't be mobile-only
• You work well remotely and asynchronously. This is a distributed role on a tiny team. You write clearly, you post updates without being asked, you unblock yourself, and you don't go quiet for two days
• At least four hours of daily overlap with 09:00–17:00 Berlin time (CET/CEST)
• You're comfortable working from underspecified problems. As a small company we can't hand you full designs and implementation plans — you'll need to ask the right questions, propose solutions, and make calls. In return, you get creative freedom
• A self-directed, structured way of working, you thrive with a lot of ownership and little supervision
• Dedication: we don't do inhumane startup hours, but when it matters - a release, a deadline, a critical fix
• Fluent English, written and spoken. German is a plus, not a requirement

Nice to have, not required

• Interest or experience in software security, our product passed an intense security audit and we intend to keep that bar high
• Experience with accessibility, or with building for older users
• Experience with DiGA, medical devices, or other regulated environments
• Startup or consultancy background
• DevOps experience (CI/CD, cloud infrastructure)

You are probably not right if

• You need a large team around you. For now it's you, a hands-on CTO, and a part-time engineer. Specialists to hand things off to come later, you'll help hire them
• You're looking for greenfield-only work. A big part of this job is improving a live product with real users and real constraints
• You need someone to hand you tickets, or a manager checking in daily. Remote and self-directed is the whole shape of this role
• You see your scope as highly specialised. We need technical solutions for internal tooling here and there too. If touching a HubSpot integration feels beneath you, this isn't the right place

Benefits

What we offer

• Purpose: your code measurably helps people — clinically proven, prescribed by doctors, reimbursed by statutory health insurance
• Real ownership: as the next full-time engineer, you'll own features end to end and have a direct say in how we build
• Stability with startup energy: 5+ years on the market, revenue from reimbursement partners
• Genuinely remote, genuinely worldwide: work from wherever you're based, with flexible hours around a light overlap window. Our office in Potsdam is there if you ever want it
• Your choice of setup: employment or freelance, whichever suits you
• No office politics: a small, focused team where the energy goes into the product, not into positioning
• Straight talk: you've just read our salary range and a list of reasons not to apply. That's how we operate internally too

If you have any questions, please don't hestitate to reach out :)

The initial phase will be a short questionnaire, followed by a small project and 1-2 live interview rounds.
