Backend Engineer - Tech Lead

Our client is a European MedTech software and R&D company developing advanced technologies across medical imaging, robotics, and Software as a Medical Device (SaMD). Their platforms are used by medical device companies and research groups to accelerate innovation in image-guided interventions, AI-powered imaging workflows, and next-generation clinical applications.

The role

In this position, you will join the company as a Senior Fullstack Developer with a strong backend focus, taking ownership of the architecture and technical direction of cloud-based web applications built on top of an established medical imaging platform. Acting as a hands-on Tech Lead, you will drive backend services, APIs, and cloud infrastructure while mentoring developers, defining engineering standards, and contributing to key architectural decisions across the stack.

This is a highly impactful role for someone who enjoys balancing technical leadership with hands-on engineering, helping shape scalable software systems that support advanced medical technologies used by clinicians, researchers, and device manufacturers globally.

Key responsibilities

• Lead technical direction across backend architecture, APIs, cloud infrastructure, and deployment strategy.
• Design, build, and maintain scalable backend services and RESTful APIs.
• Collaborate closely with frontend engineers to develop end-to-end cloud-based web applications.
• Own cloud deployment, monitoring, operational reliability, and DevOps best practices.
• Drive code quality through reviews, testing strategies, documentation, and engineering standards.
• Mentor developers and contribute to technical leadership within the team.
• Work cross-functionally with product, R&D, and engineering teams to shape product roadmap and platform capabilities.

Required experience and qualifications

• Minimum 5 years of professional experience in backend or fullstack software engineering.
• Strong backend development experience in Python, ideally with FastAPI; experience with Java, Node.js, Go, or C# is also valued.
• Proven experience designing and building scalable REST APIs and distributed backend systems.
• Strong understanding of relational databases and data modelling, ideally PostgreSQL.
• Hands-on experience with cloud platforms such as AWS, GCP, or Azure, including Infrastructure as Code tools like Terraform.
• Experience with containerisation and CI/CD workflows using Docker, GitHub Actions, GitLab CI, or similar technologies.
• Strong communication skills and ability to operate effectively within distributed or remote engineering teams.
• Previous experience mentoring engineers or acting as a technical lead is highly desirable.
• Nice-to-have experience includes Kubernetes, authentication and identity workflows (OAuth2, OIDC, SAML, Keycloak), monitoring and observability tooling, WebSockets/real-time systems, and frontend technologies such as React and TypeScript.

Why this role?

• Join a highly technical and mission-driven engineering environment working on software that directly contributes to medical innovation and improved patient outcomes.
• Take ownership of architecture and technical direction while remaining hands-on in development.
• Work alongside experts in medical imaging, AI, robotics, and computer vision within an international engineering team.
• Enjoy the agility and influence of a fast-moving environment combined with the stability of an established company.
• Flexible remote/hybrid working options within Germany and parts of the EU.
• Competitive compensation alongside benefits including sports programs, bike leasing, team events, and flexible working arrangements.
