• Engineer secure deployment workflows with strong attention to credential handling, certificate management, secrets isolation, and deployment guardrails
• Collaborate across engineering teams to improve platform reliability, deployment consistency, and operational efficiency
• Troubleshoot complex issues spanning applications, containers, clusters, hosts, networking, storage, and artifact distribution systems
• Mentor junior engineers and help establish engineering best practices across platform and release operations
• Continuously improve engineering workflows through automation, AI-assisted tooling, and operational best practices

• Strong understanding of:
• Platform engineering
• Release engineering
• PaaS/SaaS delivery models
• Operator-focused tooling and workflows
• Must be eligible to obtain a DOD Security Clearance

Preferred Qualifications

• Experience supporting government, defense, intelligence community (IC), or similarly regulated environments
• Strong Linux systems engineering experience, particularly in:
• RHEL/Rocky Linux environments
• Docker/container runtimes
• RKE2
• Networking and storage systems
• Host provisioning and preparation
• Security-minded engineering approach that balances automation, maintainability, auditability, and operational constraints
• Strong troubleshooting and root-cause analysis skills across:
• Application layers
• Kubernetes clusters
• Host systems
• Networking
• Artifact repositories
• Authentication and credential systems
• Demonstrated ability to mentor engineers and clearly communicate complex platform concepts to technical and non-technical stakeholders

What Success Looks Like

• Reliable, repeatable, and secure platform deployments across connected and disconnected environments
