Position Summary

We are seeking a Senior Systems Engineer with deep expertise in UNIX, and Linux platforms to lead and deliver infrastructure and platform implementation projects supporting mission-critical environments.

This role is heavily focused on design, build, migration, modernization, and integration initiatives, rather than day-to-day operations. The ideal candidate will have a strong background in deploying enterprise systems, leading technical implementations, and driving infrastructure transformation efforts, particularly in hybrid UNIX/Linux ecosystems.

Key Responsibilities

• Lead and execute end-to-end infrastructure implementations, including system builds, migrations, upgrades, and decommissioning activities
• Design and deploy UNIX and Linux environments aligned with enterprise architecture standards
• Drive platform modernization initiatives, including OS upgrades, consolidation, and automation adoption
• Implement and integrate application server platforms (e.g., WebSphere, WebLogic) within high-availability architectures
• Perform environment build-outs for new applications, ensuring scalability, resilience, and performance requirements are met
• Collaborate with cross-functional teams (application, network, storage, security) to support project delivery and system integration
• Develop and execute deployment plans, runbooks, and cutover strategies for production releases
• Automate system provisioning and configuration using Ansible, shell scripting, or similar tools
• Conduct performance validation, tuning, and capacity planning during and after implementation
• Implement security controls, system hardening, and compliance requirements as part of build processes
• Support data center migrations, cloud/hybrid transitions, and platform transformations
• Produce and maintain engineering documentation, including build standards, architecture diagrams, and implementation guides
• Provide post-implementation knowledge transfer to operations teams and limited escalation support

You will be successful in this role if you have:

• Experience with application server deployment and configuration (e.g., WebSphere, WebLogic)
• Demonstrated ability to execute system migrations, upgrades, and large-scale rollouts
• Experience with automation and Infrastructure as Code practices (Ansible, shell scripting, or similar)
• Solid understanding of system performance tuning, validation, and troubleshooting during project delivery
• Familiarity with enterprise security standards and implementation of hardened builds
• Experience working in regulated or highly controlled enterprise environments
• Knowledge of virtualization platforms (e.g., VMware) and enterprise storage solutions
