This role sits within a collaborative, forward-thinking team that values innovation, resilience, and proactive problem-solving. You’ll work closely with project managers, technical leads, and third-party suppliers, all while shaping solutions that are secure by design and aligned to strict compliance requirements.

What you'll be doing:

• Designing, deploying, and maintaining RHEL systems across multiple environments.
• Leading automation and hardening efforts to ensure secure, resilient infrastructure.
• Collaborating with internal teams and third-party suppliers to resolve complex issues.
• Supporting integration of RHEL systems with a range of other services and applications.
• Producing and maintaining documentation and procedures for both operational teams and end-users.
• Providing input into disaster recovery, monitoring, and security planning processes.

What you’ll bring:

• Active SC Clearance and eligible for DV Clearance.
• Proven expertise in Red Hat Enterprise Linux (RHEL) administration and design.
• Strong understanding of security controls, including host firewalls, SELinux, and intrusion detection.
• Knowledge of networking fundamentals, especially from a security perspective.
• Experience working in highly governed environments with tight SLAs.
• Skilled in patch management and system update procedures.

It would be great if you had:

• Experience with secure environments and familiarity with JSP 440 and SCIDA requirements.
• Proficiency in scripting (e.g., Bash, Python) for secure automation.
• Familiarity with vulnerability management tools such as OpenSCAP and Nessus.
• Exposure to Red Hat deployment tools and secure system state management.
