This senior field engineering role serves as the primary escalation point for federal customers, bridging the gap between on-site support teams and product engineering. The position requires hands-on troubleshooting across the full infrastructure stack, including bare metal, hypervisors, Kubernetes, Linux, and networking, to diagnose live production issues and drive permanent fixes. Key responsibilities involve translating vague field symptoms into structured defect reports, validating patches in customer environments, and enabling field teams through runbooks and training. The role also focuses on maintaining federal compliance through DISA STIG hardening and audit readiness. This opportunity appeals to engineers seeking deep technical impact within a collaborative culture that values mentorship and continuous improvement. The position is hybrid onsite, located in Oklahoma City, Dallas, Houston, or Montgomery, and requires an active Secret clearance and U.S. citizenship.
