Develop, maintain, test, and document software for systems, simulations, and performance analysis environments
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- and software-in-the-loop (HITL and 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
Required Qualifications
Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related technical discipline
0–2 years of professional experience developing software for technical systems (experience can include internships, co-ops, or academic projects)
Programming experience in C#/C or Python
Experience developing software on Linux and Windows based systems
Familiarity with PNT concepts (e.g., Global Navigation Satellite Systems (GNSSs), inertial navigation, timing, sensor fusion)
Experience integrating software with complex systems, simulations, or external hardware components
Ability to obtain and maintain a U.S. DoD security clearance
Participate in team technical interchange meetings to describe technical activities, progress, issues, improvements, and more
Desired Qualifications
Academic or project experience with GPS/GNSS signal processing, navigation algorithms, or timing systems
Strong verbal and written communications skills
Experience with modeling, simulation, or digital twin environments
Familiarity with real-time or embedded systems
Experience with HITL/SITL test architectures or laboratory integration
Experience supporting DoD programs, laboratory R&D, or operational prototyping efforts
Basic Compensation: $80,000 - $100,000 (For Beavercreek, OH Only)
