You’re enthusiastic, collaborative, and comfortable working with teammates across a range of technical backgrounds. You also meet the following qualifications:

• Bachelor’s degree in Engineering, Computer Science, Systems Engineering, or related field (or equivalent experience) with 8+ years of relevant experience; 6+ years with a Master’s
• Active TS/SCI clearance and ability to obtain/maintain a TS/SCI with Polygraph
• Strong Linux proficiency
• Hands‑on experience with containers and Kubernetes
• Experience with CI/CD orchestration and GitLab
• Familiarity with Elasticsearch, Logstash, and Kibana
• Demonstrated success working in cross‑functional engineering environments

Bonus Points

You’ll Stand Out Even More If You Bring

• Experience operating systems at scale
• Knowledge of Agile methodologies
• Development experience (Bash, PowerShell, SALT, Python, Groovy, Java, etc.)
• Experience supporting enterprise or production systems
• Familiarity with:
