About The Position

About the Team: The Vehicle Software team develops the safety-critical software that runs on Terran R. The work spans a distributed, real-time control system operating under extreme conditions like Mach 5 atmospheric flight, with a deployment pace that allows you to see your code run on rocket engines daily. The team is building new system architecture from the ground up and just as importantly, testing, releasing, and deploying it. You don't need an aerospace background: what matters is experience with high-reliability software for complex systems. This is a rare opportunity to shape the foundation of Terran R's software stack while directly influencing performance, reliability, and flight success. About the Role: We are seeking an experience Embedded Software Engineer with deep expertise in motor control system development. This engineer will help integrate and tune the motor-control library within our application framework, ensuring reliable performance of high-speed motors used in rocket applications. The ideal candidate combines strong theoretical background in motor control principles with practical, hands-on experience implementing and validating control algorithms on real hardware.

Requirements

  • 5+ years of experience in embedded systems with a focus on motor control
  • Strong proficiency in C/C++ and familiarity with FreeRTOS or similar RTOS environments
  • Expert knowledge of PMSM/BLDC motor control principles and applications, including current, velocity, and position control loops, and advanced techniques such as FOC
  • Experience with basic debugging tools: oscilloscope, logic analyzer, power analyzer

Nice To Haves

  • Prior experience with Field Oriented Control (FOC)
  • Prior work experience in aerospace industry
  • Strong understanding of PWM generation strategies, resolver/encoder interfaces, and ADC synchronization and timing for precise control feedback
  • Familiarity with network stack implementation, socket-level programming, and transport protocols such as UDP, TCP/IP, and multicast data distribution
  • Experience with firmware development in RTOS environment (preferably FreeRTOS)
  • Familiarity with hardware in the loop testing (HITL) and CI/CD pipelines for embedded systems
