Job description
As Senior Backend Developer, you will take the lead on our backend systems, designing and building the APIs and services that power our applications.
Your tasks will involve a combination of the following:
- Designing and developing scalable backend services using server-side JavaScript/TypeScript (e.g., Node.js), relational databases (e.g., PostgreSQL), caching (e.g., Redis), and message queues (e.g., RabbitMQ).
- Building performance-critical services using systems programming languages (e.g., Rust) where speed and reliability matter most.
- Architecting robust backend services that handle high throughput while meeting strict healthcare compliance requirements (e.g., TI-Konnektor integrations, gematik certifications).
- Working with modern cloud infrastructure: containerization and orchestration (e.g., Docker, Kubernetes) on cloud platforms (e.g., GCP, AWS).
- Working on greenfield projects as well as evolving existing systems.
- Contributing to open source projects, or collaborating with the team building fun projects during our Open Fridays (usually on a Wednesday) :)
Requirements
Our primary requirement is a genuine passion for creating exceptional backend systems, writing clean, efficient code, and an eagerness to collaborate on innovative projects.
Coupled with at least 4-5 years of hands-on backend development experience , you're the kind of seasoned professional we're excited to invite for a coffee chat!
What we're looking for:
- Strong experience with server-side JavaScript/TypeScript (e.g., Node.js, Express)
- Experience with systems programming languages for performance-critical services (e.g., Rust)
- Solid understanding of relational databases and query optimization (e.g., PostgreSQL)
- Familiarity with caching and message queues (e.g., Redis, RabbitMQ)
- Experience with API design (e.g., REST)
- Experience building and operating distributed systems
- Familiarity with containerization and orchestration (e.g., Docker, Kubernetes)
- Experience with cloud platforms (e.g., GCP, AWS)
We embrace AI tools to improve our workflows - and we're looking for someone who shares that mindset.
As a senior, you should be a great communicator who can explain complex technical ideas to different audiences. You're self-directed, collaborative, and able to navigate complex problems with pragmatic solutions.
Fluency in English is crucial for our international team. And if you can sprinkle in some German, that's a delightful bonus we appreciate.
Benefits & conditions
- A competitive salary
- Flexible working hours and hybrid work (mainly from home, with one office day per week in Berlin or Cologne)
- Learning budget for conferences, courses, and books
- Choose the gear you like
- Relocation support if you're moving to Berlin or Cologne
- Minimal meetings: we take planning seriously and spend our time coding, not in meetings
Backend systems don't build themselves, so we make sure to keep the office stocked with coffee, fruits, Club Mate & snacks. We hold regular team events - dinners, game nights, chess evenings, and board games at the office, plus seasonal whole-company events like go-kart racing and escape rooms.
