Job Description
KBR is seeking an experienced Principal Software Engineer to support the MSEIT contract at Space Systems Command (SSC). This role combines hands-on software development, technical leadership, and architecture support across multiple mission-focused software teams supporting U.S. Space Force capabilities. Unlike engineers dedicated to a single application or team, this position operates across multiple development efforts, helping solve complex technical challenges, accelerate delivery, improve architectural consistency, and support integration across mission systems. The successful candidate will be equally comfortable writing production code, reviewing architectural decisions, mentoring development teams, and collaborating with systems engineers, product owners, and mission stakeholders. This role serves as a technical force multiplier across the program and helps ensure consistency in engineering practices, architectural approaches, and software quality. The program is built around modern software engineering practices, event-driven architectures, cloud-native technologies, DevSecOps, and CI/CD-oriented delivery approaches.
