• Implement real‑time control and monitoring algorithms for power processing and propulsion systems
• Integrate software with digital hardware (PPU/APU and related avionics systems)
• Support hardware‑in‑the‑loop (HIL) testing, debugging, and system validation
• Develop and maintain low‑level communication interfaces (SPI, I2C, CAN, UART, custom protocols)
• Collaborate with electrical engineers on system architecture and integration
• Transition embedded software responsibilities from external subcontractors to internal ownership
• Ensure compliance with aerospace, reliability, and DoD cybersecurity/CUI requirements

• BS in Electrical Engineering, Computer Engineering, or related field (MS preferred)
• Strong proficiency in C/C++ for embedded systems
• Experience with microcontrollers and real‑time embedded development
• Familiarity with hardware/software integration and debugging

• Experience with RTOS‑based systems
• Background in aerospace, defense, robotics, or power electronics applications
• Experience with FPGA‑integrated embedded systems
• Knowledge of control systems or spacecraft subsystems
• Experience supporting flight or mission‑critical software development

Due to the nature of work performed under U.S. government contracts and applicable security and contractual requirements, this position is limited to U.S. citizens.
