Sr Unix Engineer information

What does a Sr Unix Engineer do?

A Sr Unix Engineer is responsible for designing, implementing, and maintaining Unix-based systems within an organization. Their duties include installing and configuring servers, monitoring system performance, troubleshooting issues, and ensuring security and reliability. They also manage system upgrades, automate administrative tasks, and provide technical support to other teams. Senior engineers typically have several years of experience and play a key role in planning and optimizing Unix infrastructure.

What are the key skills and qualifications needed to thrive as a Sr Unix Engineer?

To thrive as a Sr Unix Engineer, you need deep expertise in Unix/Linux systems administration, scripting (such as Shell, Python, or Perl), and a relevant degree or equivalent experience. Familiarity with configuration management tools (like Ansible or Puppet), virtualization platforms, and certifications such as Red Hat Certified Engineer (RHCE) are often expected. Analytical thinking, strong problem-solving abilities, and effective communication help you excel in troubleshooting and collaborating with cross-functional teams. These skills are essential to maintain system reliability, implement efficient solutions, and ensure seamless IT operations in complex enterprise environments.

What are the typical challenges a Sr Unix Engineer faces when supporting large-scale enterprise systems?

As a Sr Unix Engineer, you may frequently encounter challenges such as managing complex server environments with minimal downtime, troubleshooting performance bottlenecks, and ensuring robust system security. Working in large enterprises often involves coordinating with cross-functional teams, handling critical incidents quickly, and implementing automation to streamline system management. Staying updated with evolving technologies and best practices is also essential to maintain high availability and efficiency within the Unix environment.

What is the difference between Sr Unix Engineer vs Unix System Administrator?

AspectSr Unix EngineerUnix System Administrator

Employer & Industry UsageTech companies, data centers, enterprise ITIT departments, hosting providers, enterprise organizations

While both roles require similar certifications and work in Unix environments, Sr Unix Engineers focus on system design and development, whereas Unix System Administrators handle daily maintenance and troubleshooting. The roles complement each other within IT teams, with the engineer often guiding system architecture and the administrator ensuring operational stability.

Job description

Location: Remote (U.S.) or Arvada, CO (Hybrid/On-Site Available)
Job Type: Full-Time

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
Required Qualifications Commercial UNIX Experience

Candidates must have strong hands‑on production experience with at least two of the following platforms:

  • IBM AIX
  • HP-UX
  • Oracle Solaris

Experience supporting all three platforms is highly preferred.

Technical Expertise

Qualified candidates should demonstrate experience with many of the following:

  • Enterprise UNIX administration and troubleshooting
  • Logical Volume Manager (LVM)
  • Filesystem administration (JFS/JFS2, ZFS, VxVM, SVM)
  • High Availability clustering (PowerHA/HACMP, Serviceguard)
  • Shell scripting (ksh, sh, bash)
  • Performance tuning and diagnostics
  • Enterprise storage (SAN, Fibre Channel, multipathing)
  • NFS and SMB/CIFS administration
  • TCP/IP networking and troubleshooting
  • LDAP, Active Directory integration, PAM, and Kerberos
  • Patch management and security hardening
  • Operating system installation, upgrades, and disaster recovery
  • Boot process troubleshooting across enterprise UNIX platforms
Preferred Qualifications

Experience with any of the following is a plus:

  • PowerHA / HACMP
  • Serviceguard
  • Solaris Zones or Logical Domains (LDOMs)
  • NIM or Ignite‑UX
  • Veritas Volume Manager
  • SPARC systems
  • IBM Power Systems
  • NetApp, EMC, Ceph, GPFS, or Lustre storage
  • Python, Perl, or Ruby automation
  • Legacy UNIX platforms such as Tru64 or IRIX
What We're Looking For

We're looking for a senior‑level engineer who:

  • Has extensive production experience supporting enterprise UNIX environments
  • Can independently troubleshoot highly complex technical issues
  • Enjoys solving difficult infrastructure problems
  • Is comfortable working directly with customers
  • Thrives in a collaborative, highly technical team

This position is not intended for Linux administrators with limited exposure to AIX, Solaris, or HP‑UX. Candidates should have substantial experience administering commercial UNIX operating systems in production environments.

Why Join Us?
  • Work alongside a team of highly experienced UNIX professionals
  • Support mission‑critical enterprise environments
  • Access to a dedicated multi‑platform UNIX lab
  • Remote flexibility within the United States
  • Opportunities to continue expanding your UNIX expertise
  • High‑impact work with a wide variety of enterprise customers
Benefits
  • Medical, Dental & Vision Insurance
  • Health Savings Account (HSA) with employer contributions
  • Employer‑funded Life Insurance
  • 401(k) with employer contributions
  • Employee Ownership Program
  • Unlimited Paid Time Off
  • Paid Company Holidays
  • Flexible work environment (Remote, Hybrid, or On‑Site)
