• Find systemic gaps with security and IT, then ship platform and deployment changes that reduce risk.
• Deliver solutions that are scalable, repeatable, maintainable, and secure.
• Coordinate with information security, IT, software, and other partners.

BASIC QUALIFICATIONS:

• Bachelor's degree in computer science or another STEM discipline; OR 2+ years of professional experience operating production infrastructure and high school diploma or equivalency certificate in lieu of a degree.
• 5+ years of experience operating on-premises Kubernetes in a production environment.

PREFERRED SKILLS AND EXPERIENCE:

• Python or Go for platform tooling and automation.
• Linux internals and troubleshooting.
• Observability, alerting, and operational readiness for production platforms.
• CI/CD or GitOps-style delivery onto Kubernetes.

• TCP/IP at the level needed to build and debug cluster networking.
• Root-cause debugging under time pressure.

ADDITIONAL REQUIREMENTS:

• Must be willing to work extended hours and/or weekends as needed.
• This role requires you to be onsite. Hybrid or remote work will not be considered.
• Must have a valid driver's license.
• Ability to pass Air Force background check for Cape Canaveral.

How to prepare and behave

This is editorial guidance, not information from the employer.

• Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
• Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
• Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
• Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
• Be honest about gaps; say what you did to learn and how fast you can close them.
• Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
• When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
• Send a short thank-you message within a day, mentioning one thing you discussed.
• Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.
