Fullstack / Product Engineer (f/m/d) for Flutter & Node.js (100% Homeoffice)

About This RoleAI processing…

Key Responsibilities

• 1
  Frontend: Evolve our Flutter app (iOS & Android) with a strong focus on accessibility and usability for people aged 50+
• 2
  Backend: Design and build our Node.js APIs and services for new feature-development
• 3
  Product: Work closely with medical and product colleagues – your voice matters in what we build and how
• 4
  Quality: Establish code review practices, testing strategy, and engineering standards that hold up in a regulated medical-software environment
• 5
  As an add-on: If you're interested in DevOps, you can help shape our cloud infrastructure, CI/CD pipelines, and deployment processes – but that’s not the core of the job

Requirements

• 3-5+ years of professional software engineering experience, including relevant mobile and backend work
• Strong Flutter/Dart skills, or a proven ability to ramp up quickly (e.g. coming from React Native or native mobile development)
• You're comfortable working from underspecified problems. As a small company, we can't hand you full upfront designs and implementation plans – you'll need to ask the right questions, propose solutions, and make calls. In return, you have creative freedom
• A self-directed, structured way of working – you thrive in a small team with lots of ownership
• Dedication: we don't do inhumane startup hours, but when it matters – a release, a deadline, a critical fix – we count on you to go the extra mile
• Fluent English; German is a plus, but not required
• Experience working in a startup or consultancy environment
• Interest or experience in software security – our product has passed an intense BSI security audit, and we intend to keep that bar high
• The ambition to grow into a leadership role as the team scales
• Experience with accessibility or building for older users
• DevOps experience (CI/CD, cloud infrastructure)
• Experience with DiGA, medical devices, or other regulated environments
• 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 will come later – you'll help hire them.
• You're looking for greenfield-only work. A big part of the job is improving an existing, live product with real users and real constraints
• You see your scope as highly specialized. Technical solutions are also needed for internal tooling here and there. If touching a HubSpot integration feels beneath you or out of scope, this isn't the right place.
• You consider yourself primarily an "AI orchestrator." We use AI tools too, but we're looking for someone who values learning, deep thinking, and actually understanding the systems they build.
