Job summary

EY seeks an AI Systems Engineer to own the security and trust fabric of EY’s AI-native platform, spanning identity, secrets, cryptography, and attestation across cloud, on‑prem, edge, and air‑gapped environments.

You will enforce identity and cryptographic controls, drive auditability, and partner with security and platform teams to ensure compliant, scalable trust across multi‑tenant deployments. The role emphasizes security‑first principles and regulated environments.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Security, or related technical field, or equivalent experience.
• 8+ years in security engineering, identity/PKI, or trust infrastructure, with hands‑on production ownership.
• Deep, hands‑on expertise with workload identity (SPIRE/SPIFFE), IAM (Keycloak/Entra ID), and secrets management (OpenBao/Vault).
• Strong grounding in PKI, X.509 certificate lifecycle (cert‑manager), key management, and transit encryption.
• Working experience with confidential compute and hardware attestation (TDX, SEV‑SNP, SGX, NVIDIA CC, or equivalents) and secure boot (Intel TXT).
• Experience delivering identity and secrets consistently across multi‑tenant, multi‑environment (cloud/on‑prem/edge/air‑gapped) platforms.
• Proven track record operating under compliance, security, or regulatory constraints with audit‑grade evidence requirements.
• Ability to define clean ownership boundaries and consumption contracts with platform, data, and runtime teams.

Responsibilities

• Own workload identity and secrets management across environments (SPIRE/ODIS, Keycloak/Entra ID, OpenBao, cert-manager).
• Build confidential compute environments (TEE, boot security, secure DPU architecture) that are isolated and audit-ready.
• Establish a platform‑wide identity model to propagate identity end‑to‑end through telemetry and policy enforcement.
• Own the cryptographic lifecycle: issuance, rotation, revocation, expiry of certificates and keys with minimal secret sprawl.
• Enforce attestation policy across nodes, enclaves, and workloads with evidence for audit.
• Collaborate with Enterprise Security / Cloud Platform / SRE for alignment to standards and audit readiness.
