Government engineering services firm specializing in systems integration and automation

Software Development Fulton, MD 11–50 employees Founded 2019 Partnership

Set of X is an 11–50 person engineering services firm selling directly to U.S. Government customers. The tech stack is operationally mature—Python, Java, Kubernetes, AWS, monitoring (Prometheus/Grafana), testing (JUnit, Cucumber, k6)—and the project list reveals heavy lifting: kernel modules, CI/CD automation, network integration, and data analysis in classified environments. Hiring is accelerating with a 4:1 engineer-to-other-roles ratio and 85% senior/lead positions, indicating customer contracts are pulling in experienced individual contributors rather than team-building or management scales.
