The Senior IDAM Services Engineer will be responsible to support AIDA / ReAI and enterprise workloads that require secure machine-to-machine identity, secrets, certificates and automated access controls. The role will engineer secure integration patterns across applications, CI/CD pipelines, vaults, certificate lifecycle services and identity governance platforms.

Make an Impact by:

• Engineer and operate enterprise secrets-management patterns for AIDA / ReAI applications, AI agents, workloads, service identities and automation accounts.

  Integrate applications and CI/CD pipelines with approved vault and secrets-management services so credentials are retrieved at runtime and are not hard-coded in source code, scripts or configuration files.

• Implement automated secret rotation, credential expiry, revocation and recovery patterns, including application validation after rotation.
• Design vault integration patterns using APIs, workload identity, just-in-time retrieval and least-privilege access, with clear separation between human and non-human identities.
• Engineer certificate lifecycle automation covering request, issuance, deployment, renewal, replacement, revocation and expiry monitoring for supported application and workload certificates.
• Integrate applications with the enterprise Certificate Lifecycle Management platform and approved certificate authorities, eliminating manual certificate handling wherever technically feasible.
• Implement proactive monitoring and alerting for certificate expiry, failed renewal, failed deployment, secret-rotation failures and vault integration health to prevent service outages.
• Define audit logging requirements for secrets, certificates and non-human identities, and forward relevant security and operational events to enterprise SIEM/monitoring platforms.
• Support agentic AI identity governance by establishing unique identity, ownership, purpose, privilege, credential, lifecycle and traceability requirements for AI agents and autonomous workloads.
• Design and implement SailPoint integration models for agentic AI and non-human identities, including authoritative ownership, account correlation, access governance, certification/review, provisioning/deprovisioning and evidence reporting where appropriate.
• Develop governance patterns that distinguish employee/contractor identity lifecycle from machine, workload and AI-agent identity lifecycle while maintaining consistent enterprise control outcomes.
• Integrate identity and secrets controls with cloud platforms, APIs, DevSecOps tooling and enterprise applications using REST APIs, web services, connectors and automation scripts.
• Perform security and operational readiness validation before production deployment, including failure scenarios, rollback/recovery, monitoring, support ownership and runbook readiness.
• Maintain architecture diagrams, integration specifications, SOPs, support runbooks, credential/certificate ownership records and audit evidence required for operational handover.
• Support incident investigation and root-cause analysis for secret exposure, authentication failures, certificate expiry, failed rotations and non-human identity access issues.
• Drive continuous improvement by identifying manual processes and recurring operational risks and replacing them with scalable, system-enforced automation.
• Work with Cyber Security, Data Governance, PKI, PAM, IDAM/SailPoint, Cloud and application teams to ensure solutions comply with Singtel security, audit and operational standards.
• Transfer knowledge to BAU teams and ensure new integrations are supportable before the end of the contract engagement.

Skills for Success:

• Degree or diploma in Computer Science, Cybersecurity, Information Technology, Engineering or equivalent practical experience.
• Minimally 8 years of hands-on engineering experience in two or more of: secrets management/PAM, PKI/certificate lifecycle, IAM/IGA, DevSecOps automation, cloud security or application security.
• Hands-on experience integrating applications or pipelines with enterprise vaults and automating credential retrieval/rotation.
• Practical PKI knowledge including CSR, certificate chains, TLS, issuance, renewal, revocation and automated deployment.
• Experience with REST APIs, scripting/automation and CI/CD integration.
• Experience implementing monitoring, audit logging and security-event forwarding for production services.
• Working knowledge of identity lifecycle, least privilege, RBAC and non-human/service identity controls.
• Secrets management and vault integration
• PKI and certificate lifecycle automation
• SailPoint / IGA integration and lifecycle governance
• REST API, Python/PowerShell or equivalent automation
• CI/CD and DevSecOps integration
• Monitoring, logging and operational readiness
• Strong problem solving and ownership; clear written and verbal communication; able to work across security, infrastructure, application and product teams; disciplined documentation and production-readiness mindset.
• Understanding of agentic AI security concepts, non-human identity governance, credentialless/workload identity patterns, certificate automation and audit evidence requirements.

Good to have:

• Relevant certifications in CyberArk, SailPoint, cloud security, PKI, DevSecOps or identity security.
• CyberArk Privilege Cloud / CCP / Conjur / Secrets Hub and CyberArk Certificate Lifecycle Management.
• SailPoint IdentityIQ or Identity Security Cloud integration experience.
• Azure/Entra ID, AWS or GCP workload identity and managed identity patterns.
• Experience governing AI agents, service principals, API identities or machine identities.
• Experience with AI/agent platforms, workload identity federation, SIEM integration and infrastructure-as-code.
• Able to explain complex identity/security risks in simple business terms and influence teams toward automation rather than manual controls.
• Familiarity with AI governance frameworks and secure-by-design patterns for autonomous agents and tool/API access.
