About the role

Key responsibilities & impact

Own end-to-end engineering delivery of the agentic AI platform
Set technical vision and architecture direction for a multi-tenant agentic platform built on AWS Bedrock AgentCore, Strands Agents SDK, and Cedar/AVP authorization
Recruit, hire, and develop pillar leads and senior engineers across Identity & Access, Agent Runtime, Observability & FinOps, Catalog & Registry, and Evals & Testing
Drive platform security posture — threat modeling for agent delegation chains, prompt injection defence, cross-tenant isolation, and regulatory compliance (SOC2, OCC, FFIEC)
Establish engineering standards — ADRs, SDK architecture patterns, code review culture
Build and operate the agent onboarding pipeline — enabling adjacent business teams to build, certify, and deploy agents on the platform
Define SLOs, operational readiness criteria, and incident response processes for a banking-grade production platform
Manage cross-pillar dependencies and technical risk — credential flows, MCP Gateway governance, audit pipeline completeness, and multi-tenant data isolation
Partner with Security to establish pre-GA sign-off gates including penetration testing, SAST/DAST integration, and compliance certification
Drive FinOps discipline — per-tenant cost attribution, LLM usage optimization, and infrastructure right-sizing
