Senior Infrastructure Engineer – AIX & Linux – hybrid | Revel IT

OUR GOAL: Treat our consultants and clients the way we would like others to treat us! Interested in joining our team? Check out the opportunity below and apply today!

Senior Infrastructure Engineer – AIX & Linux Our Columbus, Ohio client is growing their infrastructure team and has a contract-to-hire opportunity for a Senior Infrastructure Engineer – AIX & Linux who is hungry to own their platform and drive real change. As the Senior Infrastructure Engineer for AIX and Linux, you’ll set the direction for UNIX/Linux compute at enterprise scale, build automation that genuinely eliminates toil, and bring hybrid cloud instincts to a team that’s actively modernizing.

On-site expectations are on-site Monday through Thursday and remote on Fridays.

You’ll own reliability, security, and performance across AIX, Linux, VMware, storage, and DR—partnering closely with Security, App Dev, Data, and Networking. If you love deep‑dive performance troubleshooting, have strong opinions about platform standards, and get excited about what modern tooling can do for infrastructure operations, this role was built for you.

• Lead lifecycle management for AIX (LPARs, VIO, NIM) and Linux (RHEL/SLES/Ubuntu): provisioning, patching, kernel updates, tuning, and OS hardening.
• Maintain platform standards: golden images, baselines, and configuration drift detection.
• Tune OS and kernel parameters, multipathing, and I/O stacks for latency‑sensitive workloads.

• Administer and optimize VMware vSphere (ESXi, vCenter, DRS/HA, vMotion), HMC, and shared storage patterns including vSAN or enterprise arrays.
• Operate hybrid IaaS/PaaS workloads in AWS/Azure: compute, storage, networking, identity integrations; apply landing zones and guardrails.
• Enforce configuration management with Ansible, Terraform, and Git‑based pipelines for repeatable deployments.

• Analyze utilization and recommend rightsizing, reservations or savings plans, storage tiering, and archival strategies.
• Automate to eliminate toil: scheduled automation, self‑healing playbooks, autoscaling where appropriate.
• Track and report cloud spend and data center TCO; propose optimizations and lifecycle retirements.
• Standardize images and baselines to reduce variance and operational overhead.

• Apply CIS benchmarks and vendor hardening guides for AIX, Linux, VMware, and cloud workloads; meet patch and vulnerability SLAs.
• Integrate IAM and RBAC patterns across on‑premises and cloud; enforce MFA, least privilege, and key rotation.
• Implement encryption in transit and at rest, certificate lifecycle, and secrets management (for example Hashi Corp Vault, cloud KMS).
• Design, test, and exercise BC/DR runbooks including multi‑site failover and restore validation.

• Provide architectural guidance on AIX/Linux modernization, VMware consolidation, storage rationalization, and cloud adoption.
• Evaluate new tools through pilots and structured production onboarding.
• Build observability across metrics, logs, and traces (for example Prometheus, Grafana, Splunk, Solar Winds).
• Forecast compute, memory, network, and storage growth; drive procurement and expansion planning.

• Maintain architectural diagrams, runbooks, service catalogs, and CMDB or asset records.
• Produce operational health, capacity, and cost dashboards; communicate risk registers and remediation.
• Document incidents, RCAs, lessons learned, and onboarding guides.
• Partner with Security, App Dev, Data, and Networking; coordinate vendors and MSPs to SLOs.
• Champion AIX-to-Linux modernization and cloud migration pathways; own the platform rationalization roadmap and drive lifecycle retirements proactively. Champion reliability, automation, and continuous improvement as cultural defaults, not afterthoughts.

Dense OS logs, long Ansible/Terraform modules, and repetitive incident patterns are exactly where AI earns its keep. We use enterprise‑approved tooling…
