Senior Embedded Software Engineer

Integrated Solutions for Systems, Inc. is hiring a Senior Embedded Software Engineer in Dayton, OH (onsite) to support the R-EGI program, focused on resilient PNT for military aircraft. In this role, you will develop, integrate, and test embedded C/C++ software that processes navigation inputs and helps qualify system performance through hands-on engineering and verification activities.

This position emphasizes practical embedded Linux development, sensor and interface integration, and system-level troubleshooting, alongside collaboration with navigation engineers to evaluate sensor fusion and estimation. You will also contribute to testing strategy, code quality through reviews and releases, and technical milestones tied to formal program reviews and qualification.

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, including work with device drivers, operating system services, and hardware interfaces.
• Integrate GPS/GNSS receivers, IMUs, and other navigation inputs; collaborate with navigation engineers on 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 performance evaluation 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.

Requirements

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a closely related technical field.
• 8+ years of embedded software engineering experience.
• Strong proficiency in C and C++ for embedded or real-time applications.
• Hands-on experience developing, integrating, and debugging software on embedded Linux systems.
• Experience working with hardware interfaces, device drivers, or low-level software, including 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.

Technologies

• C, C++, embedded Linux, GPS/GNSS, IMUs, Git, cross-compilation toolchains, oscilloscopes, logic analyzers, debuggers

Benefits

Preferred Qualifications

• Experience with military aviation PNT systems, GPS/GNSS receivers, IMUs, inertial navigation systems, or integrated GPS/INS solutions.
• Experience with navigation estimation, Kalman filtering, sensor fusion, or operation in GPS-degraded and GPS-denied environments.
• Experience with aircraft avionics interfaces such as MIL-STD-1553 or ARINC 429.
• Experience developing and integrating systems using modern embedded processing platforms, such as the AMD/Xilinx Zynq UltraScale+ MPSoC.
• Experience with real-time Linux, VxWorks, INTEGRITY, or another real-time operating system.
• Experience with software-in-the-loop or hardware-in-the-loop testing and system integration labs.
• Proficiency in Python for test automation, data analysis, or diagnostic tools.
• Ability to read electrical schematics, interface diagrams, and hardware documentation.
• Experience supporting formal software qualification or airworthiness activities.
• Active DoD Secret clearance or higher.
