Senior Linux Engineer

We are seeking a highly skilled Linux Engineer to lead the design, standardization, automation, and optimization of enterprise-wide Linux platforms. This role is a hands-on engineering position focused on creating reusable solutions and capabilities for Linux Operations and Infrastructure teams, rather than routine system administration tasks. The ideal candidate will bring deep expertise in Linux environments and a strong engineering mindset to drive platform improvements and operational excellence.

Key Responsibilities

- Design and maintain enterprise-wide Linux platform standards and automated build solutions.
- Develop standardized OS and container golden images for bare-metal, VMware, OpenShift, and cloud environments.
- Manage and enhance Red Hat Satellite, Kickstart, PXE, DHCP, and Redfish for automated provisioning.
- Engineer and optimize RHEL platforms, focusing on kernel, CPU, memory, I/O, and network/TCP performance.
- Define and implement Linux security, hardening, configuration, and compliance standards.
- Develop monitoring and observability solutions for Linux OS and Dell/HPE server infrastructure, integrating with tools such as Splunk, ELK, SIEM, and AppDynamics.
- Automate patching, firmware updates, configuration management, monitoring, and compliance using Ansible, Bash, and Python.
- Develop AI-driven solutions to improve Linux engineering and business-as-usual operations.
- Support Linux platforms across OpenShift, VMware, Kubernetes, and cloud environments.
- Serve as a Level 3 escalation point for critical incidents and lead root cause analysis efforts.
- Collaborate with Infrastructure, DevOps, Security, Enterprise Architecture, and BAU teams to establish future-state Linux standards.
- Work closely with technology vendors and service partners to drive platform improvements and roadmap initiatives.
- Participate in a 24x7 on-call rotation to respond to critical incidents.

Required Qualifications

- Bachelor’s degree in Computer Science, IT, Engineering, or a related field, or equivalent experience.
- Over 12 years of experience in Enterprise Linux environments, including at least 5 years in Senior Linux Administration and 5 years in Linux Engineering roles.
- Strong hands-on expertise with RHEL versions 6 and onwards.
- Extensive experience with Red Hat Satellite Server, preferably including Kickstart.
- In-depth knowledge of PXE, DHCP, Redfish, and automated OS provisioning.
- Proven ability to create standardized OS and container images across on-premises, VMware, OpenShift, and cloud platforms.
- Strong expertise in Red Hat OpenShift and practical experience with Kubernetes in cloud environments.
- Proficiency in automation and scripting tools such as Ansible, Bash, Python, Packer, and familiarity with CI/CD and DevOps technologies.
- Solid understanding of network and infrastructure protocols including DNS, NFS, NTP, SNMP, SMTP, Active Directory, TCP/IP, and Ethernet.
- Excellent Linux troubleshooting skills, including kernel analysis, performance tuning, and optimization.
- Experience working with enterprise monitoring, logging, and SIEM solutions.
- Comprehensive knowledge of Linux security hardening and configuration management.
- RHCE certification is required; RHCA certification is a plus.

Preferred Qualifications and Benefits

- AWS and Azure certifications are advantageous and will be considered a strong asset.

This role offers the opportunity to work at the forefront of Linux engineering within a dynamic enterprise environment, collaborating with diverse teams and driving innovation through automation and AI-driven solutions. Candidates should be prepared to engage in critical incident response and contribute to the continuous improvement of Linux platforms at scale.
