What are the responsibilities and job description for the Senior DevSecOps Engineer position at Trabus Technologies?
Position: Senior DevSecOps Engineer
Full-time
Location: San Diego, CA
Clearance Level: Secret
Trabus Technologies (TRABUS) is a minority-owned, service-disabled veteran-owned small business (SDVOSB) headquartered in San Diego, California. Since 2010, TRABUS has delivered cutting-edge solutions in wireless technologies, cybersecurity, artificial intelligence, and space systems engineering to federal and private sector clients.
We take pride in supporting the nation’s most critical missions with a focus on innovation, agility, and mission assurance.
SUMMARY: TRABUS has an opportunity for a Senior DevSecOps Engineer to take complete ownership of our mission-critical project infrastructure. This role requires hands-on management of the entire on-premise technology stack, from physical hardware and the virtualization layer (VMware) to the Linux OS and the CI/CD pipelines. This individual will be responsible for all on-premise systems, which exist in both connected and fully air-gapped network zones. A key responsibility will be managing a dual-toolchain environment, leveraging a GovCloud-hosted GitLab instance for the connected network and a dedicated Jenkins server within the air-gapped lab. This is a lead role with the opportunity to drive the evolution of our infrastructure by proposing and implementing new technologies.
Work Arrangement: This is a hybrid role. The position requires a minimum of two days per week on-site at the lab. The remainder of the week can be worked remotely. Flexibility for additional on-site presence is mandatory to support hands-on infrastructure tasks (e.g., hardware installations, troubleshooting) as they arise.
