Senior Application Engineer - AI (Python, FastAPI & LLM)

5-8+ years of software engineering experience, with a strong focus on backend or full-stack production development.

Expert-level skills in Python and the surrounding production ecosystem (async, FastAPI, Pydantic, pytest).

Experience with Java or TypeScript is useful, though Python is strongly preferred.

Strong REST API design experience, database modeling (SQL and at least one NoSQL store), and event-driven patterns.

Working knowledge of frontend frameworks (React or equivalent) sufficient to wire UI components into your APIs.

Working understanding of LLM APIs and how AI features are integrated — prompt invocation, streaming, retries, fallbacks.

End-to-End Feature Delivery:

Own the dev work on a Strike Team — REST APIs, frontend wiring, feature logic, and integration with AI components — for one high-complexity or strategic AI productization project at a time.

Technical Execution:

Make day-to-day implementation calls, contribute to design reviews, and make sound trade-off decisions on your features; escalate cross-cutting concerns to the Engineering Manager.

Partner with your AI Engineer to bring LLM-based components into production paths — prompt invocation, response handling, fallbacks, observability — running on AWS Bedrock.

You'll shape how these components are integrated, collaborate on the design decisions that affect the product, and bring the AI Architect in on the deeper algorithmic calls.
