Job description

Hi there!

At Data4Life, we develop secure, standards-compliant digital health solutions that empower researchers and public health institutions to advance evidence-based medicine. As a nonprofit supported by the Hasso Plattner Foundation, we build scalable research infrastructures — supporting international standards such as FHIR and OMOP — and collaborate with some of the world's leading clinical institutions.

As a Senior Full-Stack Engineer, you will work on a medical image annotation application built in collaboration with Mount Sinai Health System in New York, one of the largest and most respected academic medical centers in the United States. Your code will support clinical researchers working with real patient data at scale.

Tasks

Your future role

  • Design, build, and ship high-quality frontend and backend features — writing

    accessible, performant, maintainable, and well-tested code.
  • Contribute to software design and architecture decisions, and take part in code reviews across the full stack.
  • Work closely with designers, QA, and product management as part of an

    integrated team to deliver well-crafted, user-centered software.
  • Engage directly with customers and users — joining feedback sessions and user

    research to build a deep, end-to-end understanding of the product and

    the problems it solves.
  • Design with security at the core — shaping authorization concepts and data protection architecture from the ground up, including the documentation that supports review and sign-off by our clinical partners.

Requirements

What you need to succeed

  • A university degree (M.Sc.) in Computer Science, Software Engineering, or a related discipline.
  • 3+ years of professional experience as a software engineer or full-stack developer, or equivalent experience.
  • Strong frontend skills: deep fluency in HTML, CSS, and JavaScript/TypeScript, with hands-on experience in React or equivalent.
  • Solid backend experience: proficiency in Go (Golang), Kubernetes, and Docker, or equivalent.
  • Experience with relational databases; we use PostgreSQL.
  • Professional written and spoken English, German language skills a plus.

Benefits

Why you will love working with us

  • High level of personal responsibility and creative freedom
  • Work on socially impactful projects in the healthcare sector
  • Collaboration with leading partners from research, technology, and healthcare
  • A diverse, interdisciplinary, and international team working across three locations (Potsdam, Berlin, and Singapore)
  • Flexible working models with the option to work from home
  • Permanent employment contract with 30 days of vacation
  • Attractive employee benefits, e.g. private supplementary health insurance, public transport ticket

We particularly welcome applications from members of the LGBTQI+ community, individuals with a migration background, people of color, and people with disabilities or chronic illnesses.
