We're looking for a Senior UNIX Engineer who brings traditional platform depth along with modern engineering practices.

You'll help lead the design, deployment, and lifecycle of mission-critical UNIX platforms and services, while contributing to DevOps tooling, Git-driven workflows, hybrid cloud strategies with an automation mindset.

This is a key role in a high-trust team that powers secure, compliant infrastructure for a global financial institution.

Key responsibilities include :

Core UNIX Engineering & Support

• Design, secure, build, and maintain resilient UNIX environments
• Own OS lifecycle strategy: patching, upgrades, security baselines, and hardware refresh planning.
• Maintain solutions and performance-tuned enterprise systems.

DevOps, SRE & Automation

• Embrace an SRE mindset: treat infrastructure as code, prioritize availability and observability, and automate toil.
• Automate provisioning, compliance checks, and config enforcement
• Use GitHub for source control, peer-reviewed automation pipelines, change tracking, and documentation versioning.
• Contribute to CI/CD workflows for infrastructure as code deployments, and integrate with enterprise tools like ServiceNow, Jenkins, or GitHub Actions.

Security

• Ensure UNIX systems are hardened and compliant with security frameworks.
• Manage OS-level security policies including firewall rules, kernel parameters, selinux policies and secure configurations.
• Integrate systems for identity and privileged access management.
• Support audit, forensic, and security event investigations in coordination with InfoSec teams.
• Regularly review and remediate security vulnerabilities identified by Qualys, Nessus, or other scanning tools.
• Contribute to incident response planning, patching SLAs, and compliance reporting.
• Design and maintain logging, audit trails, and syslog/SIEM integrations
• Authentication, Authorization, and Directory Services
• Integrate UNIX systems with enterprise identity management platforms
• Implement and enforce secure access controls, sudo policies, and RBAC schemes.
• Collaborate with IAM and InfoSec teams on audit readiness, access provisioning, and PAM integrations.

Monitoring, Reliability & Incident Response

• Integrate systems with monitoring tools like Dynatrace, vROps, and custom health scripts.
• Support alerting, auto-remediation, and telemetry for performance and availability.
• Participate in on-call rotations, DR testing, and RCA for high-impact incidents.

Hybrid Cloud & Platform Modernization

• Support UNIX workloads running on VMware and prepare platforms for future cloud integration.
• Assist with cloud-readiness assessments, infrastructure modernization efforts, and immutable infrastructure adoption.
• Collaborate with Cloud, DevOps, and Cybersecurity teams on secure hybrid operating models.

Documentation & Governance

• Maintain robust documentation
• Ensure all platforms and automation meet compliance standards.
• Lead or contribute to engineering design reviews, change boards, and audit remediation efforts.

The ideal candidate should have a fair amount of the following skills & experience

• Proven ability to handle deep technical challenges, that have high visibility.
• Prior experience and exposure to UNIX engineering with deep expertise in large enterprise environments.
• Strong understanding of centralized authentication/authorization.
• Proficiency in shell scripting (bash, ksh, sh); strong familiarity with Python, and Ansible.
• Proven experience with infrastructure-as-code principles, Git-driven config management, and CI/CD pipelines leveraging GitHub Actions and Ansible / AWX
• Familiarity with automated validation, monitoring, logging, and alerting frameworks.
• Passion for automating operations tasks, reducing technical debt, and building sustainable systems.
• Proactive, detail-oriented, and comfortable in fast-moving, audit-heavy environments
• Diligent with ability to cross check / robust validation of outcomes and results
• Excellent communication, documentation, and cross-team collaboration and contribution skills
• Experience in financial services or other highly regulated sectors
• Exposure to hybrid cloud operations, containerization (e.g., Podman, Docker, Tanzu), or cloud-native UNIX alternatives.
• Familiarity with enterprise CI/CD tooling (Jenkins, GitHub Actions, ServiceNow integration).
• Relevant certifications (preferred but not required).
