Job summary

IS4S is seeking a Senior Embedded Software Engineer to develop, integrate, and test software for the R-EGI program, which combines GPS/GNSS and inertial sensors to support resilient PNT for military aircraft. The role requires hands-on embedded Linux work, hardware bring-up, and collaboration across systems, navigation, hardware, and test teams.

Applicants should have strong C/C++ skills, experience with device drivers, and the ability to diagnose hardware/software integration issues.

Qualifications

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a closely related technical field.
• 8 or more years of embedded software engineering experience.
• Strong C and C++ proficiency for embedded or real-time applications.
• Hands-on experience developing, integrating, and debugging software on embedded Linux systems.
• Experience with hardware interfaces, device drivers, or low-level software and diagnosing hardware/software integration issues.
• Experience using laboratory tools such as oscilloscopes, logic analyzers, or debuggers to troubleshoot embedded systems.
• Experience with software requirements, interface definitions, verification, and configuration management.
• Experience with Git, cross-compilation toolchains, and automated builds.
• Ability to obtain and maintain a DoD Secret security clearance.

Responsibilities

• Design, develop, test, and maintain embedded C/C++ software for navigation processing, device interfaces, middleware, and system control.
• Develop and debug software on embedded Linux platforms, including interactions with device drivers, operating system services, and hardware interfaces.
• Integrate GPS/GNSS receivers, IMUs, and other navigation inputs; work with navigation engineers to implement and evaluate sensor-fusion and estimation functions.
• Diagnose system-level issues involving software timing, sensor data, electrical interfaces, and hardware behavior.
• Support hardware bring-up and software integration in laboratory and system integration lab environments.
• Develop automated tests, diagnostic tools, and scripts that improve software integration, regression testing, and troubleshooting.
• Support simulation, software-in-the-loop, and hardware-in-the-loop testing, including evaluation of performance when GPS is degraded or unavailable.
• Translate system and interface requirements into software designs, test procedures, and verification evidence.
• Participate in code reviews, configuration management, defect resolution, and software releases.
• Support technical reviews and program milestones, including PDR, CDR, TRR, and qualification activities.
• Mentor less experienced engineers and help the team resolve complex embedded software issues.
