Our engineering group is split into roughly 60 product teams, each owning its services end to end, with on-call shared across time zones. Headquartered in Berlin since 2000, the company now sells in 40 countries and supports customers in 11 languages. We keep recurring meetings to Tuesdays and Thursdays where we can.

Job summary

We're looking for a Backend Developer to join our team. This is a remote role. Backend role focused on API design, data modelling and making slow things fast. You'll work mostly on server-side code: services, queues, databases and the glue between them. Little to no frontend work. This role is fully remote within Germany. You will need a reliable internet connection and a quiet place to work.

Main duties

• Secure endpoints with OAuth 2.0, JWT validation and proper input checks
• Design and build REST and gRPC APIs in Go, Java or Python
• Containerize services with Docker and deploy them to Kubernetes or ECS
• Coordinate with frontend and mobile engineers on API contracts and versioning
• Write integration and contract tests so API changes don't break consumers
• Instrument services with metrics, structured logs and OpenTelemetry traces
• Document APIs in OpenAPI and keep the docs current
• Add caching with Redis where it actually helps, and remove it where it doesn't

Qualifications

• 2-4 years of backend development experience in a production environment
• Familiarity with Docker and CI/CD pipelines
• Working knowledge of message queues or streaming platforms
• Experience designing and versioning HTTP APIs
• Hands-on experience with AWS, GCP or Azure services
• Comfort reading logs, metrics and traces to debug problems in production
• Clear written communication, including design docs

Preferred

• NoSQL stores such as MongoDB, Cassandra or DynamoDB
• Terraform or Pulumi
• Elasticsearch or OpenSearch

Compensation and benefits

• Company pension scheme
• Holiday pay
• Childcare allowance
• Christmas bonus
• Urban Sports Club membership
