-- EN --

Join Probatix Health GmbH and help shape the future of laboratory diagnostics!

We’re looking for a motivated Backend Developer who doesn’t just build our platform but owns it—end to end, from architecture to operations. If you live ownership, find pragmatic solutions, and want real impact in digital health, you’ll feel at home here.

• Develop & Optimize: Backend with PHP 8,
  Symfony 7, and API Platform
  .
• Integrations & Data Flows: e.g.
  Mirth Connect
  , HL7
  , FHIR
  —robust, secure interfaces.
• API Design: Build and evolve internal and external APIs (versioning, auth, rate limiting).
• Collaboration: Work closely with Frontend (React) and Product; clean interfaces and clear handovers.
• Performance & Scale: Profiling, caching strategies, queuing,
  nginx tuning.
• Quality: Unit/integration tests, code reviews, clean code, security best practices.
• Dev Ops & Infra Ownership: CI/CD, containerization (
  Docker
  ), orchestration (e.g.
  Kubernetes
  ), cloud (
  AWS/GCP
  ), IaC, observability (logs, metrics, tracing), alerting & incident handling.

• 2+ years as a backend developer in production (ideally digital health or other regulated domains).
• Strong skills in PHP 8,
  Symfony 7, and modern API development.
• Experience with system integrations and healthcare standards (
  HL7, FHIR
  ) plus the web stack (
  nginx
  ).
• Hands-on with CI/CD
  , Docker/K8s
  , cloud infra,
  IaC
  , monitoring/alerting.
• Ownership mindset: you take responsibility, create clarity, and deliver reliably.
• Open, constructive, high quality bar—and the drive to move things forward.

• A key role in a self-funded company with a clear mission and short time-to-impact.
• Ownership over micromanagement: real decision‑making power and direct influence on architecture, roadmap, and operations.
• Modern setup in Berlin (hybrid possible), focused collaboration, minimal bureaucracy.
• Room to shape standards: help define coding guidelines and infrastructure blueprints.
