Integrated Solutions for Systems, Inc. is seeking a Senior Embedded Software Engineer for onsite work in Dayton, OH. In the R-EGI program, the role focuses on resilient PNT capabilities for military aircraft, with hands-on embedded development spanning software design, integration, and qualification.
This position centers on embedded C/C++ work for navigation processing and device interfaces, alongside deep debugging and test support across embedded Linux, hardware bring-up, and sensor integration. You will collaborate with navigation engineers to implement and evaluate estimation and sensor-fusion functions, and help drive verification evidence through testing, reviews, and program milestones.
Role Overview
Develop, integrate, and test embedded software for navigation processing, interfaces, middleware, and system control. Support lab and system integration activities from early bring-up through qualification, including simulation and hardware-in-the-loop evaluation when GPS is degraded or unavailable.
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 interactions with device drivers, OS services, and hardware interfaces.
- Integrate GPS/GNSS receivers, IMUs, and other navigation inputs; work 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 to improve software integration, regression testing, and troubleshooting.
- Support simulation, software-in-the-loop, and hardware-in-the-loop testing, including performance evaluation under GPS-degraded or GPS-denied conditions.
- 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 milestones including PDR, CDR, TRR, and qualification activities.
- Mentor less experienced engineers and help the team resolve complex embedded software issues.
Required Qualifications
- Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a closely related technical field.
- 8+ years of embedded software engineering experience.
- Strong C and C++ proficiency for embedded or real-time applications.
- Hands-on experience developing, integrating, and debugging on embedded Linux systems.
- Experience working with hardware interfaces, device drivers, or low-level software, plus diagnosing hardware/software integration issues.
- Experience using laboratory tools such as oscilloscopes, logic analyzers, or debuggers.
- 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.
