Senior Software Engineer

Overview

Trinzic is the future independent company being formed through the planned spin-off of KBR's Mission Technology Solutions business, expected in January 2027. Trinzic will launch as a global organization with more than 18,000 employees supporting customers worldwide. This role supports research and applied DoD programs, including modeling, simulation, and operationally relevant systems, with a primary focus on position, navigation, and timing (PNT) systems.

For candidates who join the KBR Mission Technology Solutions business before the spin-off, employment will transition to Trinzic after separation without the need to reapply.
