AI Systems Engineer - Secure Execution - Senior

About the role

We are seeking AI Systems Engineers to own the security and trust fabric of EY’s AI-native platform. This role is crucial for ensuring that EY’s AI workloads are deployable in highly regulated environments.

Responsibilities

• Own workload identity and secrets management: SPIRE/ODIS, Keycloak/Entra ID (IAM), OpenBao (secrets store), cert-manager (X.509 lifecycle), PKI issuers/roots, and transit encryption.
• Build confidential compute environments: TEE (TDX/SEV-SNP/SGX/TrustZone/CCA/NVIDIA CC), Intel TXT boot security, and secure DPU architecture (DOCA).
• Establish the platform-wide identity model so every workload, agent, and service carries a verifiable, propagated identity.
• Own the cryptographic lifecycle: issuance, rotation, revocation, and expiry of certificates, keys, and roots.
• Enforce attestation policy: trust at boot and runtime, and capture attestation evidence for audit.
• Partner on a dotted-line basis with Enterprise Security / Cloud Platform / SRE to ensure independent review, alignment to enterprise trust standards, and audit readiness in regulated client contexts.

Requirements

• Deep expertise in workload identity, secrets management, PKI, and cryptographic lifecycle at production scale across multiple environments.
• Strong understanding of confidential compute, trusted execution environments, hardware roots of trust, and remote attestation.
• Security-first mindset: thinking in terms of provable trust, blast radius, least privilege, and cryptographic attribution.
• Comfortable operating across cloud, on-prem, edge, and air-gapped environments with consistent identity and trust mechanisms.
• Strong communicator able to explain trust, identity, and attestation tradeoffs to engineers, architects, auditors, and leadership.
• Orientation toward auditability and evidence: able to translate regulatory expectations into technical controls and demonstrable proof.

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.
