Embedded Software Engineer; Missiles & UAS

• Employee Type Exempt FT
• Required Degree 4 Year Degree

IS4S is seeking a motivated and disciplined embedded software engineer with a minimum of 3 years of professional experience to support the development of flight software and mission logic for advanced defense platforms. This role focuses on the implementation, debugging, and testing of real‑time software in C and C++ for missile systems and Unmanned Aircraft Systems (UAS).

The ideal candidate possesses a strong foundational knowledge of embedded systems and a "hands‑on" approach to integrating software with complex aerospace hardware.

• Software Implementation: Develop and maintain modular code in C and C++ for embedded processors and Real‑Time Operating Systems (RTOS), ensuring adherence to project‑specific coding standards.
• Debugging & Troubleshooting: Conduct board‑level debugging and software troubleshooting using JTAG debuggers, oscilloscopes, and logic analyzers to identify and resolve timing or peripheral interface issues.
• Hardware Integration: Support hardware‑software integration and "bring‑up" activities for new circuit card assemblies and flight controllers.
• Verification & Testing: Develop and execute unit tests, integration tests, and Hardware‑in‑the‑Loop (HITL) simulations to verify software performance against mission requirements.
• Technical Documentation: Contribute to the generation of technical artifacts, including software design descriptions, interface control documents (ICDs), and test reports.
• Peer Participation: Actively participate in peer code reviews and formal technical reviews (e.g., PDR, CDR) to ensure software quality and design consistency.
• GNC Support: Assist in the implementation of Guidance, Navigation, and Control (GNC) algorithms on embedded targets, focusing on optimization and execution efficiency.

• Education: Bachelor of Science in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field.
• Experience: 3+ years of experience in embedded software development, preferably within the defense or aerospace industry.
• Programming
  
  Skills:
  
  Proficiency in C and C++ with an understanding of object‑oriented design and memory management in resource‑constrained environments.
• Embedded Fundamentals: Familiarity with microcontrollers (e.g., ARM Cortex‑M/R/A), interrupt handling, and common communication protocols (SPI, I2C, UART, CAN).
• Development Tools: Experience with version control systems (Git), IDEs (e.g., VS Code, Eclipse), and cross‑compilation tool chains.
• RTOS Knowledge: Exposure to real‑time operating systems such as FreeRTOS, VxWorks, or similar deterministic environments.
• Security: Ability to obtain and maintain a DoD Secret Security Clearance.
