Job summary

EY is seeking AI Systems Engineers to own the security and trust fabric of EY’s AI-native platform, spanning identity, secrets, cryptographic and attestation layers across cloud, on‑prem, edge, and air‑gapped environments.

You will architect and enforce platform‑wide identity models, manage cryptographic lifecycles, and drive attestation policies to support auditable, regulated workloads with strong governance across multi‑tenant deployments.

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, PKI).
• Build confidential compute environments (TEE, secure boot, secure DPU architecture) for attestable, audit‑ready workloads.
• Establish platform‑wide identity models for verifiable identity across telemetry, cost attribution, and policy enforcement.
• Own issuance, rotation, revocation, and expiry of certificates, keys, and roots with no long‑lived secret sprawl.
• Enforce attestation policy for nodes, enclaves, and workloads and capture evidence for audit.
• Collaborate with Enterprise Security / Cloud Platform / SRE to ensure compliance and audit readiness for regulated clients.
