  • Execute approved standard changes such as service restarts, configuration updates, and agent reinstalls. 
  • Perform health checks and first-level troubleshooting for GPFS, LSF, OpenShift, and RStudio environments. 
  • Use Ansible Tower and Red Hat Satellite for patching and configuration management.  
  • Maintain and improve automation scripts and reporting tools for recurring operational tasks.
  • Collaborate with the on-site team and L3 SMEs for escalated or hardware-dependent incidents. 
  • Participate in the on-call rotation approximately once per month, providing after-hours support for high-priority incidents. 
  • Escalate and coordinate tasks with L3 Support Engineers.
  • Ensure ServiceNow tickets and incident bridges are properly updated during off-hours events. 
 

What we expect:

  • Strong experience supporting RHEL 6–9 and Ubuntu 20/22/24 in production environments, including patching, monitoring, and incident response.  
  • Hands-on experience with VMware ESX, GPFS, and LSF, and working knowledge of OpenShift and RStudio services.  
  • Strong understanding of Ansible Tower, Red Hat Satellite, Puppet, and shell scripting. 
  • Experience with ServiceNow, TrueSight, and PATROL for monitoring and ITSM processes. 
  • Solid grasp of Linux networking and remote troubleshooting practices in large enterprise environments. 
  • 3–5 years of experience in Linux/Unix support within enterprise environments. 
  • RHCSA and/or ITIL v4 Foundation certification.
  • Ability to work independently and effectively within remote, structured support operations.
  • Excellent problem-solving, documentation, and communication skills.
  • EST availability
 

Nice to have:

  • Familiarity with AIX and other Unix platforms (HP-UX, Solaris).

We offer:

  • Competitive compensation
  • Remote or office work
  • Flexible working hours
  • Healthcare benefits: medical insurance and paid sick leave
  • Continuous education, mentoring, and professional development programs
  • A team with an excellent tech expertise
  • Certifications paid by the company
