Responsibilities
- Set the technical direction for AI engineering, evolving the technical vision, architecture, and roadmap for AI powered products and capabilities.
- Lead by example through hands-on engineering, establishing best practices and guiding teams towards scalable, reliable, and maintainable solutions.
- Lead complex AI delivery from concept to production, taking end-to-end accountability for significant technical and architectural decisions.
- Navigate trade-offs across capability, quality, speed, cost, latency, risk, and scalability.
- Act as the go-to technical authority for complex AI challenges, unblocking teams through architectural guidance, rapid prototyping, and hands-on intervention.
- Drive the design, development, and deployment of LLM-powered applications, including RAG, vector search, tool calling, agentic workflows, and context management.
- Establish robust approaches to evaluation, observability, tracing, monitoring, fallback mechanisms, rate limiting, and graceful degradation.
- Embed security, safety, and governance throughout the AI development lifecycle.
- Establish appropriate controls for prompt injection, PII, output guardrails, human-in-the-loop oversight, and auditability.
- Partner with InfoSec, Data Privacy, Legal, and AI Governance teams to meet regulatory requirements, protect customer data, and deliver trustworthy AI experiences.
- Work closely with engineering managers, product leaders, and other technical stakeholders to shape AI development and deployment strategies.
