Senior Software Engineer
About The Position
KBR is seeking a Senior Software Engineer to lead the development, integration, and evaluation of software solutions for systems operating in varied environments. The role supports modeling, simulation, and operationally relevant systems across research and applied Department of Defense programs, primarily involving position, navigation, and timing (PNT) systems. The position requires deep expertise in software development and PNT fundamentals, including designing and implementing algorithms, guiding technical execution, and working across system, algorithm, and integration boundaries. The engineer will collaborate with systems engineers and hardware teams to design, analyze, and mature PNT capabilities in laboratory and field environments. Candidates joining KBR's Mission Technology Solutions business before its planned spin-off are expected to transition to Trinzic when the separation is complete without needing to reapply.
Requirements
- Bachelor’s degree in Computer Engineering, Electrical Engineering, or Aerospace Engineering.
- Strong verbal and written communication skills.
- At least 8 years of professional experience developing software for technical systems.
- Proficiency in C/C++ or Python, with experience owning complex software components or frameworks.
- Experience developing software on Linux- and Windows-based systems.
- Strong understanding of PNT concepts, such as GNSS, inertial navigation, timing, and sensor fusion, and associated error sources.
- Experience integrating software with complex systems, simulations, or external hardware components.
- Ability to obtain and maintain a U.S. DoD security clearance.
Nice To Haves
- Advanced experience with GPS/GNSS signal processing, navigation algorithms, or timing systems.
- Experience developing or evaluating alternative or resilient PNT approaches.
- Experience with modeling, simulation, or digital twin environments supporting PNT analysis.
- Familiarity with real-time or embedded systems.
- Experience with HIL/SIL test architectures, laboratory integration, or field testing.
- Experience supporting DoD programs, laboratory R&D, or operational prototyping efforts.
Responsibilities
- Design, develop, and maintain software for systems, simulations, and performance analysis environments.
- Lead development and implementation of algorithms grounded in first-principles physics, including measurement modeling, error characterization, and estimator behavior under non-ideal conditions.
- Architect and integrate software frameworks for simulation, analysis, and testing.
- Integrate software with hardware-in-the-loop (HITL), software-in-the-loop (SITL), and digital twin environments.
- Define and develop interfaces between software components and external systems.
- Lead and support test planning, execution, and analysis for PNT-focused experiments, demonstrations, and evaluations.
- Collaborate with systems engineers to align system requirements, hardware constraints, and software designs.
- Review, mentor, and provide technical guidance to junior and mid-level engineers.
- Document software designs, algorithms, and test results for technical reviews and customer deliverables.
- Participate in technical interchange meetings to communicate technical activities, progress, issues, and improvements.
