What will you do as a VP, Unix Engineer?

Unix Engineering and Operations

• Manage and support enterprise Unix environments (AIX, RHEL) across production, DR, and non production systems.
• Design, implement, and maintain secure, standardised Unix configurations aligned with CIS Benchmarks and internal security policies.
• Lead large scale patching operations, ensuring minimal downtime and full compliance with vulnerability management requirements.
• Perform deep dive troubleshooting (L3) for complex incidents, root cause analysis, and permanent remediation.
• Participate in internal and external project meetings as the Unix representative, ensuring infrastructure readiness and alignment with enterprise standards.

Ansible Automation and Infrastructure as Code (IaC)

• Develop, maintain, and optimise Ansible playbooks and roles for configuration management, patching, provisioning, and compliance enforcement.
• Lead the conversion of existing Puppet manifests into Ansible based Infrastructure as Code, ensuring consistency and reusability.
• Collaborate with the Ansible Automation Platform (AAP) team to design scalable automation pipelines, define access controls, and integrate with enterprise authentication systems.
• Design automation dashboards and reporting mechanisms for visibility into configuration drift, patch compliance, and deployment success rates.
• Mentor junior engineers on Ansible best practices, coding standards, and version control workflows (Git).

ServiceNow Integration and Process Automation

• Design and implement ServiceNow integrations to enable automated Unix service catalogues (e.g., user provisioning, access requests, patch scheduling).
  
• Develop workflows and APIs that connect Unix automation tools (Ansible, BigFix) with ServiceNow for end to end request fulfilment.
  
• Work with the Enterprise Service Management (ESM) team to define SLAs, approval flows, and compliance checkpoints within automated processes.
• Ensure all automation workflows are auditable, secure, and aligned with ITIL and change management practices.
• Drive continuous improvement of Unix service delivery through automation metrics and feedback loops.

Patching Design and Vulnerability Management

• Architect and maintain a comprehensive patching framework for Unix systems, integrating with tools such as BigFix, Ansible, and ServiceNow.
• Define patching cycles, rollback strategies, and validation procedures to ensure operational stability.
• Automate pre- and post-patching validation, vulnerability reconciliation, and compliance reporting.
• Collaborate with the Cybersecurity team to ensure patching processes meet internal and external audit requirements.
• Continuously evaluate new patching technologies and methodologies to improve efficiency and reduce manual effort.

Compliance, Standards, and Audit Readiness

• Implement and maintain Unix security baselines in alignment with CIS, NIST, and internal security frameworks.
• Automate and conduct regular attestations for Files/Directories, firewall rules, and system access.
• Partner with the Cybersecurity Architecture and Defence (CSAD) team to roll out new compliance initiatives across Unix platforms.
• Track and close audit findings within agreed timelines, ensuring sustainable control implementation.

Continuous Improvement and Technology Evaluation

• Evaluate emerging technologies such as Kubernetes, containerisation, and next generation Unix OS versions for potential adoption.
• Conduct proof of concepts (POCs) and provide recommendations for platform modernisation.
• Contribute to the Unix roadmap by identifying opportunities for automation, standardisation, and performance optimisation.

What qualifications or skills should you possess in this role?

• Bachelor’s degree in Computer Science, Information Technology, or related discipline (or equivalent practical experience)
• Minimum 5–8 years of hands on experience in Unix system administration (AIX and RHEL).
• Proven track record in automation and configuration management using Ansible or similar tools.
• Experience designing and managing large scale patching and vulnerability remediation frameworks.
• Familiarity with ServiceNow, BigFix, and ITIL based operational processes.
• Strong understanding of Unix security hardening and compliance frameworks (CIS, NIST, ISO 27001).
• Exposure to Kubernetes, Terraform, or cloud native infrastructure is advantageous

Technical Skills

• Operating Systems: AIX, RHEL, Solaris (for decommissioning/migration).
• Automation Tools: Ansible, Ansible Automation Platform, Puppet (legacy), Terraform (preferred).
• Patching & Compliance: BigFix, Satellite, or equivalent patch management tools.

• Security & Compliance: CIS Benchmarking, vulnerability scanning, audit remediation.
• Scripting: Shell, Python, or YAML for automation and orchestration.

Preferred Certifications

• Red Hat Certified Engineer (RHCE) or equivalent.
• IBM Certified AIX Administrator.
• Red Hat Ansible Automation Certification.
• ITIL Foundation or equivalent service management certification.
