About the Role
We're seeking an experienced Senior UNIX Systems Administrator with deep expertise in commercial UNIX environments, specifically AIX, HP-UX, and Solaris.
This is not a Linux administration position with occasional UNIX work. We're looking for a true UNIX expert who enjoys solving complex production issues, supporting enterprise customers, and working with technologies that many organizations still rely on for mission-critical operations.
You'll work directly with customers to troubleshoot, diagnose, and resolve challenging infrastructure issues involving operating systems, storage, clustering, networking, virtualization, and performance optimization.
If you're passionate about enterprise UNIX and enjoy tackling problems others can't solve, we'd love to hear from you.
Responsibilities
- Resolve advanced UNIX infrastructure and operating system issues for enterprise customers
- Troubleshoot complex storage, networking, performance, boot, and clustering problems
- Support production environments running AIX, HP-UX, and Solaris
- Implement solutions remotely and occasionally on-site
- Participate in a low-frequency on-call rotation for critical customer escalations
- Maintain and expand internal UNIX lab environments for testing and validation
- Share technical expertise through quarterly webinars and knowledge sharing
- Continuously learn and develop expertise across supported UNIX platforms
