  • Develop or review critical software components and guide engineering teams on quality, cost, speed, and maintainability trade-offs.
  • Build production AI systems using agentic applications, retrieval-augmented generation, MCP, function and tool calling, structured outputs, and multi-agent workflows.
  • Engineer production AI platforms covering inference architecture, model routing, caching, semantic retrieval, vector databases, evaluation pipelines, observability, and cost optimization.
  • Define evaluation criteria, test sets, observability, and feedback loops for accuracy, reliability, safety, latency, cost, and business impact.
  • Implement responsible AI guardrails, human oversight, access controls, privacy, security, risk, legal, and auditability practices.
  • Partner with product owners, business leaders, architects, data specialists, and delivery teams to create achievable roadmaps.
  • Mentor engineers, develop reusable patterns and reference implementations, and improve AI engineering practices.

  • Experience leading technical work across multidisciplinary teams, mentoring engineers, and influencing architecture or engineering standards without relying solely on formal authority.
  • Clear communication, commercial judgment, and ability to translate ambiguous business needs into feasible technical approaches and delivery plans.
  • Preferred experience includes consulting or professional services, client-facing technology delivery, regulated industries, enterprise risk, compliance, governance, AI application frameworks, model platforms, Kubernetes, and infrastructure as code.
