What You Will Be Doing
- You design and develop RESTful(-ish) APIs with Python (FastAPI) and implement best practices in terms of performance and security.

- You implement and optimise asynchronous workflows (e.g. with Celery and asyncio) to process large amounts of data efficiently.
- You design database architectures (Google Datastore, PostgreSQL) and take care of migration processes (e.g. Alembic) and caching mechanisms (Redis).
- You will actively participate in code reviews and help shape our development processes (CI/CD, testing).
- You will work closely with our operations team to automate talent workflows and continuously improve our platform.
- You will ensure that your projects are clearly documented so that the team can access all relevant information at all times.
