Solid judgment on core AI challenges: grounding, retrieval, context design, memory, cost, latency, and safety.
Ability to identify and implement reusable patterns in agent architecture.
Strong Python programming skills.
Proficiency in APIs, cloud platforms, and infrastructure-as-code (Terraform).
Track record of setting technical direction and mentoring other engineers.
Ability to explain complex technical trade-offs to non-technical stakeholders.
