The Role:

We are looking for a Senior Python Developer specializing in FastAPI on behalf of one of our high-growth clients to architect, build, and scale their core cloud-native backend services. In this role, you will take ownership of developing high-throughput, low-latency asynchronous APIs that power data-intensive platform features.You are a perfect candidate if you are growth-oriented, you love what you do, and you enjoy working on new ideas to develop exciting products.

What we’re looking for:

* 3+ years of dedicated, hands-on production experience building high-performance asynchronous web services with FastAPI and modern Python (3.10+). Deep mastery of Python's asyncio ecosystem, dependency injection, and Pydantic v2 data validation.

* 5+ years of total software engineering experience designing, deploying, and maintaining production-grade distributed systems and RESTful APIs.

* Solid proficiency with relational databases (PostgreSQL), writing optimized raw SQL or leveraging ORMs like SQLAlchemy and Alembic for schema migrations and query tuning. Caching layer experience with Redis is essential.

* Practical experience building decoupled services using message queues and event streaming platforms (e.g., RabbitMQ, Celery, or Apache Kafka).

* Strong daily proficiency with Docker, Kubernetes or AWS container services (ECS/EKS), and setting up CI/CD deployment pipelines (GitHub Actions, GitLab CI).

* Strict adherence to software design patterns, clean code principles, and comprehensive automated testing using pytest.

* Located in the CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones.

Nice-to-Have

* Experience with GraphQL or WebSocket integrations alongside standard REST protocols.

* Familiarity with vector databases (Pinecone, Milvus, Qdrant) or AI/LLM orchestration frameworks (LangChain, LlamaIndex) for AI-integrated backends.

* Experience migrating legacy Django or Flask monolithic architectures to decoupled FastAPI microservices.

Responsibilities:

* Design, build, and document secure, high-concurrency microservices and RESTful endpoints using FastAPI and OpenAPI/Swagger standards.

* Profile asynchronous bottlenecks, manage event loops, optimize database queries, and scale caching layers to maintain sub-millisecond response times under peak load.

* Build robust communication channels between internal services and external partner APIs using webhooks, message brokers, and background workers (e.g., Celery).

* Lead technical design discussions, establish testing benchmarks, and conduct thorough peer code reviews to ensure system reliability and security compliance.

* Collaborate closely with DevOps teams to containerize applications, monitor cloud health metrics, and streamline automated release cycles.
