• 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.
