Job Description

Python, rapid API with AI

- API & System Architecture: Design, build, and optimize scalable, asynchronous REST APIs utilizing FastAPI, Pydantic, and SQLModel / SQLAlchemy to serve high-throughput AI features.

- AI Integration & Engineering: Build production-grade workflows around LLMs and multi-agent frameworks. Architect intelligent systems implementing prompt invocation, agentic logic, and token streaming.

- Data Pipelines & RAG: Develop and maintain semantic search, Vector Database structures (e.g., Pinecone, Milvus, pgvector), and advanced Retrieval-Augmented Generation (RAG) systems.

- Production Guardrails: Implement robust system defenses for AI interactions, including request time-limits, fallbacks, exception handling, cost control boundaries, and rate limiting.

- Collaboration: Partner closely with data scientists, ML architects, and horizontal product teams to seamlessly translate raw AI models into responsive user-facing components.

- Engineering Excellence: Champion clean code practices by maintaining excellent CI/CD pipelines, comprehensive testing habits via pytest, and detailed observability/telemetry (logging, tracing LLM calls).

Required Qualifications

- Experience:



7+ years of active software engineering experience with a heavy emphasis on backend production development.

- Python Mastery: Expert-level proficiency in Python, deeply understanding asyncio, data validation via Pydantic, and advanced framework patterns.

- FastAPI Expertise: Proven track record of shipping production-ready FastAPI backends that natively leverage asynchronous workers to manage slow upstream LLM or retrieval calls.

- AI Productionization: Practical experience taking LLM features into real-world production enviornments. Understanding of streaming mechanics (Server-Sent Events/WebSockets), cost optimization, and token limitations.

- Database Design: High proficiency in relational data modeling (SQL/PostgreSQL) combined with experience in at least one NoSQL store or Vector Database.

- Cloud Infrastructure: Hands-on experience with cloud platforms (Azure preferred),
