Project focus

An established employee benefits platform needs to scale ahead of a large customer migration.

You’ll also own the backend REST API for a self-service customer portal, integrate with third-party HR systems and extend the existing transactional platform. The work is roughly 90% backend and 10% frontend.

• 5+ years of commercial Python on large, complex codebases
• Hands-on REST API development with FastAPI, Django or Flask
• Strong AWS experience, including Kubernetes (EKS) and PostgreSQL (RDS)
• Solid relational database skills, including SQL query optimisation
• Building and maintaining CI/CD pipelines (GitHub Actions, CircleCI or GitLab CI)
• A strong testing habit with pytest or similar
• Ownership from design through to delivery, including architectural decisions
• Enough React to pick up light frontend work
• Fluent English and confidence working directly with non-technical teams such as finance and customer success
• Based in Europe within CET ±2 hours and available to start by 1 December
• Desirable: fintech, payments or ledger experience, data migrations, async queues (Celery, SQS, RabbitMQ), third-party HR API integrations, Dutch
