Drive Innovation with AWS AI/ML Tooling:

Leverage and extend services like SageMaker, Bedrock, Lambda, and Step Functions to deliver reliable, performant, and secure AI workflows.

Collaborate Cross-Functionally:

Partner with data scientists, ML engineers, product managers, and business stakeholders to align AI initiatives with product and user needs. Translate complex research into scalable production systems.

Mentor Through Influence:

Though not a people manager, you’ll mentor engineers through your example, peer support, and technical insights. You’re energized by helping others get better and driving collective technical excellence.

Evaluate and Integrate Emerging AI Tech:

Stay on the bleeding edge of LLMs, embeddings, retrieval-augmented generation (RAG), vector databases, prompt engineering, and evaluation techniques. You’ll help decide which tools we adopt — and when to build our own.

Own Quality, Testing, and Documentation:

Ensure AI models are transparent, validated, and reproducible. Design evaluation protocols, bias detection methods, and documentation practices that make our work trustworthy and maintainable.
