Responsibilities

• Develop and maintain high-performance REST APIs using FastAPI.
• Work with PostgreSQL and participate in the migration to a serverless database architecture.
• Integrate and optimize vector data workflows (embeddings, similarity search, vector queries).
• Write clean, typed asynchronous Python code (AsyncIO, Pydantic).
• Build and maintain models/migrations with SQLAlchemy + Alembic.
• Integrate backend modules with external services and APIs.
• Participate in architectural discussions and propose improvements.

Requirements

• Minimum 1 year of commercial experience in backend development.
• Strong experience with Python 3.10+ and asynchronous programming.
• Proficiency with FastAPI.
• Experience with SQLAlchemy 2.x and Alembic.
• Solid understanding of PostgreSQL.

• Experience with vector databases or vector extensions

  (pgvector, Qdrant, Pinecone, Weaviate, etc.).

• Understanding of embeddings, cosine distance, similarity search.
• Familiarity with serverless database concepts.

Nice to Have

• Experience with modular backend architectures.
• Background job scheduling / async workers.
• Experience integrating cloud-based APIs.
