Job Overview:

Our client is seeking a Senior DevOps Engineer to provide a 1 year contingent engagement supporting our High Performance Computing (HPC) and Electronic Design Automation (EDA) infrastructure team. This role will work directly within the IT Datacenter (ITDC) organization and is expected to operate independently at a senior level with minimal ramp-up time. The ideal candidate brings strong hands-on experience with Linux HPC environments, infrastructure automation, SLURM workload management, datacenter migration execution, and enterprise identity integration.

Key Responsibilities:

HPC / EDA Platform Operations:

• Support and administer SLURM-based HPC compute environments, including partition configuration and migration planning

• Plan and execute HPC/EDA compute and storage infrastructure migrations across datacenters

• Develop migration strategies and evaluate implementation options, risks, dependencies, and operational tradeoffs

• Author formal Method of Procedure (MOP) documents and runbooks for infrastructure changes and service cutovers

• Coordinate cross-functionally with EDA/SPE teams, storage teams, and IDAM to deliver coordinated platform changes

• Verify storage volumes, application access, and service continuity following migrations or infrastructure changes

• Define HPC storage service tiers and gather performance and capacity requirements for EDA workloads

Linux Systems Engineering & OS Deployment:

• Administer SUSE Linux Enterprise Server (SLES) 12 and SLES 15 systems in a production HPC environment

• Build and maintain custom Linux OS images and installation media using Kiwi NG and related tooling

• Enable and maintain bare-metal provisioning workflows via RackN / Digital Rebar Provision for SLES and ESXi deployments

• Provision and configure VMware vSphere virtual machines for HPC service workloads

• Troubleshoot production issues in Linux HPC operational scripts, services, and system daemons

SLURM > SLES > RackN

Automation & Infrastructure as Code:

• Develop, maintain, and extend Ansible playbooks and roles for Linux system setup, authentication, and platform configuration

• Ensure multi-version Ansible playbook compatibility across SLES 12 and SLES 15

• Contribute GitHub pull requests, conduct code reviews, and manage inner-source infrastructure repositories

• Drive production environment changes through change management workflows using ServiceNow

Identity & Access Management:

• Integrate and configure enterprise identity systems including Okta, Active Directory, LDAP, NIS, VAS, and SSSD for Linux/HPC environments

◦ Currently using NIS and VAS, but experience with any are OK

• Audit and reconcile Linux user and group identity data (UID/GID) across multiple directory and authentication domains

• Validate authentication methods and access behavior across HPC compute and storage environments

• Extend SSSD-based corporate authentication to new compute environments and author corresponding Ansible automation

Monitoring, Logging & Operational Readiness:

• Assess and implement log management strategies, including evaluation of Splunk integration for HPC system logs

• Investigate and remediate operational issues in production Linux services (VNC, NIS, AutoFS, Zabbix, etc.)
