Senior Software Engineer

About the Role

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

In this role, you will lead the development, integration, and evaluation of software solutions for systems that operate in varied environments. The work supports modeling, simulation, and operationally relevant systems across research and applied DoD programs, with a focus on position, navigation, and timing (PNT) systems.

Key Responsibilities

• Design, develop, and maintain software for systems, simulations, and performance analysis environments
• Lead algorithm development and implementation rooted in first principles physics, including measurement modeling, error characterization, and estimator behavior under non-ideal conditions
• Architect and integrate capabilities within software frameworks supporting simulation, analysis, and test
• Integrate software with hardware-in-the-loop and software-in-the-loop (HITL&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 work, mentor, and provide technical guidance to junior and mid-level engineers
• Document software designs, algorithms, and test results to support technical reviews and customer deliverables
• Participate in team technical interchange meetings to communicate technical activities, progress, issues, and improvements

Required Qualifications

• Bachelor’s degree in Computer Engineering, Electrical Engineering, or Aerospace Engineering
• Strong verbal and written communication skills
• 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, including Global Navigation Satellite Systems (GNSSs), inertial navigation, timing, and sensor fusion, as well as 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

Desired Qualifications

• 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
