  • Collaborate with HPC engineers to ensure consistent identity resolution and caching behavior across all HPC login and compute nodes.
  • Support the standardization of the installation, configuration, and hardening of SSSD/IdM client configurations for reliable user and group resolution, RBAC rules, sudo policies, and automount on HPC nodes on Linux Rocky 9 and associated infrastructure.
• Support & Troubleshooting:
  • Monitor for and troubleshooting Kerberos, SSSD, cross-forest referral issues, as well as Azure connectivity problems.
  • Work with external collaborators (Entra ID teams) on trust implementations, maintenance, selective authentication adjustments, and incident resolution.
  • Ensure high availability and disaster recovery for IdM trust controllers and related components.
• Security & Compliance:
  • Implement least-privilege principles, selective authentication, and auditing for cross-forest access.
  • Participate in security reviews, audits, and compliance activities related to the identity infrastructure, including Entra ID-side controls.
• Collaboration:
  • Work closely with external partners’ Entra ID and IAM teams for trust configuration, network connectivity, and ongoing coordination.
  • Collaborate with TGen HPC system engineers managing storage/NFS configuration on PowerScale and VAST, as well as external partners accessing these HPC file systems on edge devices.
  • Coordinate with TGen information security team as needed to establish Entra and AD configuration policies that meet TGen requirements

Required Qualifications

• Bachelor’s degree in Computer Science, Information Technology, or related field (or equivalent experience).
• 5+ years of hands-on experience in enterprise Identity and Access Management, with strong focus on hybrid Windows-Linux and cloud/on-premises environments.
• Deep expertise in Entra ID, On-Prem AD (creating and managing forest/domain trusts, selective authentication, Kerberos, DNS integration, Entra Domain Services forest trusts).
• Track record of clearly documenting architectures, procedures, and runbooks.

Preferred Skills & Experience

• Proven ability to own the end-to-end creation and delivery of the on-premises trust and identity infrastructure while balancing operational support.
• Solid understanding of POSIX UID/GID management, SID-to-POSIX algorithmic mapping, and ensuring consistency for shared filesystem access.
• Proficiency with automation tools (Ansible, PowerShell, Azure CLI).
• Knowledge of Microsoft Entra ID hybrid scenarios, including Entra Domain Services forest trusts.
• Relevant certifications: Microsoft Certified: Identity and Access Administrator Associate (or Entra ID equivalent), or Azure Network Engineer.
• Strong troubleshooting expertise using Microsoft Entra ID tools (Sign-in Logs, Audit Logs, Provisioning Logs, and the Diagnose and Solve Problems blade), Kerberos commands (klist, nltest), packet analysis (Wireshark), Azure connectivity diagnostics (Azure Network Watcher), and Linux identity tools (sssctl, journalctl, SSSD debug logging).
• Practical experience with Rocky Linux 9 / RHEL 9, preferably in cluster environments and large-scale Linux deployments.
• Familiarity with or experience in HPC or scientific computing environments, particularly with identity challenges on login/compute nodes.

Personal Attributes
