Περιγραφή θέσης εργασίας
Senior Full Stack Engineer (Python stack)
You'll lead the design and delivery of distributed applications powering international and EU-funded projects — owning systems from architecture to UX.
What you'll do
- Architect microservices: define bounded contexts, sync (REST/gRPC) and async communication, API gateway patterns, service mesh, and clear data ownership per service.
- Build backend services in Python with FastAPI or Django REST Framework — production-grade async APIs with Pydantic models, OpenAPI/Swagger contracts, versioning, and contract testing.
- Design data layers: PostgreSQL with SQLAlchemy 2.0 (async) and Alembic migrations, MongoDB via Motor/Beanie, Redis for caching and queues, and vector stores (pgvector, Qdrant, Weaviate, Pinecone). Own indexing, partitioning, and event-driven consistency patterns using transactional messaging.
- Ship AI features: integrate LLMs (Anthropic, OpenAI, vLLM, Ollama), build RAG pipelines with LangChain/LlamaIndex or custom orchestration, write preprocessing/embedding scripts. Manage prompts and operationalize inference with batching, streaming, caching, and cost monitoring.
- Collaborate with frontend & design: define API contracts via auto-generated OpenAPI schemas, generate typed clients for the frontend, and contribute to UI work when needed.
- Own DevOps & reliability: CI/CD (GitHub Actions), Docker, Kubernetes, plus observability with OpenTelemetry, Prometheus/Grafana, and Sentry.
- Work cross-functionally with design, marketing, research, and EU consortium partners — translating research prototypes into production-grade services.
- Stay current with emerging tooling (AI agents, MCP, edge inference, async Python ecosystem, PEP-driven language evolution) and evaluate it pragmatically.
