Junior Software Engineer

KBR • Beavercreek, OH

2d • $80,000 - $100,000

About The Position

KBR is seeking a Junior Software Engineer to be mentored and developed in support of software development, integration, and evaluation for RF systems across operational and signal environments. The role supports the control, modeling, simulation, and testing of operationally relevant systems on research and applied DoD programs.

The position calls for a strong software foundation, an interest in RF system fundamentals, and the ability to work across system, algorithm, and integration boundaries with guidance from senior engineers. The engineer will work closely with systems engineers and, at times, under the direction of systems and hardware teams to implement, test, and analyze position, navigation, and timing (PNT) capabilities in constructive, laboratory, and field environments.

KBR's Mission Technology Solutions business is planned to spin off as the independent company Trinzic, expected in January 2027. Employees who join the business before the spin-off will transition to Trinzic when the separation is complete and will not need to reapply.

• Implement algorithms and models under guidance, including measurement modeling, error characterization, and estimator behavior under non-ideal conditions.
• Implement and integrate algorithms within software frameworks.
• Integrate software with hardware-in-the-loop (HITL), software-in-the-loop (SITL), and digital twin environments.
• Develop interfaces between software components and external systems.
• Support test planning, execution, and analysis for PNT-focused experiments, demonstrations, and evaluations.
• Collaborate with systems engineers to align system requirements with software designs and implementations.
• Document software implementations, interfaces, and test results to support technical reviews and deliverables.
• Participate in team technical interchange meetings to describe technical activities, progress, issues, and improvements.
