KBR is seeking a Senior Software Engineer to lead the development, integration, and evaluation of software solutions for various systems operating under various environments. This role supports modeling, simulation, and operationally relevant systems across research and applied DoD programs. These programs primarily involve, but not always, position, navigation, and timing (PNT) systems.

This position requires deep technical expertise in software development and PNT fundamentals, with the ability to design and perform algorithm implementation, guide technical execution, and work across system, algorithm, and integration boundaries. The developer will work closely with systems engineers and hardware teams to design, analyze, and mature PNT capabilities in laboratory and field environments.

Key Responsibilities

• Design, develop, and maintain software supporting 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 within software frameworks supporting simulation, analysis, and test
• Integrate software with hardware- 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, 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 describe technical activities, progress, issues, improvements, and more

Required Qualifications

• Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related technical discipline
• Strong verbal and written communications 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 (e.g., Global Navigation Satellite Systems (GNSSs),, inertial navigation, timing, 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

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

Basic Compensation:$150,000 - $200,000 (For Beavercreek, OH Only)
The offered rate will be based on the selected candidate's knowledge, skills, abilities and/or experience and in consideration of internal parity.
