Fullstack Product Engineer (fmd) for Flutter & (100 Homeoffice)

About memodio

memodio is a digital health application (DiGA) fighting forgetfulness and dementia . Our app is prescribed by doctors fully reimbursed by German statutory health insurance and recommended by leading medical a clinical trial with 140 participants we demonstrated that our app measurably improves memory performance everyday independence and quality of life. More than 10000 people already trust memodio. Weve been on the market for over five years so while we have the speed and ownership culture of a startup were past the chaotic early days. We have a validated product and paying reimbursement partners. Now were growing and were growing our engineering team with us.

What were building

Our core product is live and helping thousands of users but its far from finished. A major part of this role is evolving the existing app to better fit the needs of our users: people aged 50 often dealing with early-stage cognitive decline. That means every improvement by you has a direct visible impact on someones daily life. Beyond the core product were building new and adjacent products including ones with AI capabilities. If working with LLMs and AI-powered features excites you theres real room here to shape that from the start. If it doesnt thats fine as well.

Your role

We call this a Product Engineer role on purpose: you wont receive finished designs and implementation specs to execute. Youll get problems context and user needs and the freedom to figure out the best solution. Thats a feature not a bug: it gives you room for creativity and ownership over what ships. Today our CTO is hands-on in the codebase supported by a part-time engineer. Youll join as the next full-time engineer in a small team where your decisions carry real weight. Over the next few years we plan to grow the engineering team and we want this role to grow with it. Although not a must: If you are keen to grow into technical leadership we would love to enable this for you.

What youll do

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

What you bring

• 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)
• Youre comfortable working from underspecified problems. As a small company we cant hand you full upfront designs and implementation plans youll need to ask the right questions propose solutions and make return you have creative freedom
• A self-directed structured way of working you thrive in a small team with lots of ownership
• Dedication: we dont 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

Nice to have 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 are probably not right if

• You need a large team around you. For now its you a hands-on CTO and a part-time engineer. Specialists to hand things off to will come later youll help hire them.
• Youre 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 isnt the right place.
• You consider yourself primarily an AI orchestrator. We use AI tools too but were looking for someone who values learning deep thinking and actually understanding the systems they build.

What we offer

• Purpose: Your code measurably helps people clinically proven prescribed by doctors
• Impact: As the next full-time engineer youll shape architecture processes and culture from the ground ups
• Stability with startup energy: 5 years on the market reimbursed by statutory health insurance
• Flexibility: Work from wherever you like in Germany. We can offer you our office in Potsdam or your home its simply up to you. Flexible working hours included.
• No office politics: A small focused team where energy goes into the product not into positioning
