Power Electronics Controls Engineer

About the role

Rivian is looking for an enthusiastic Power Electronics Controls Engineer to help design, simulate and implement digital control algorithms for power converters (AC-DC, DC-DC, DC-AC). You will work closely with senior engineers to turn control theory into working firmware and test it on real hardware in the lab.

Key responsibilities

• Build converter models in MATLAB/Simulink or PLECS to analyse corner cases, transient performance and power losses.
• Develop and tune digital feedback loops (PI/PID) and PWM schemes (carrier-based, SVM) using embedded C on real-time microcontrollers.
• Assist in bringing up prototypes and debug hardware/software interactions with oscilloscopes, power analyzers and dynamic loads.
• Implement and validate digital protection mechanisms (over-current, over-voltage, thermal shutdown, fault clearing).
• Take part in design reviews and help troubleshoot electrical or timing anomalies during bench validation.
• Record simulation results, test reports and bench validation data.

Required profile

• Bachelor's degree in Electrical Engineering, or a Master's degree with 2+ years of relevant industry experience in power electronics or control systems.
• Solid understanding of classical and digital control theory, including discrete-time analysis (z-domain), digital filtering and sampling/computational delays.
• Hands-on experience developing real-time embedded C for power conversion, including direct peripheral configuration (PWM, ADC, interrupts, timers).
• Demonstrated ability to bring up converter hardware on the bench and debug with standard lab equipment.

Required skills

• Strong proficiency in MATLAB/Simulink and PLECS.
• Working knowledge of switching topologies (active PFC, LLC/DAB, 3-phase inverters) and modulation techniques.
• Preferred: TI C2000 or Sitara processors, HIL environments (Typhoon HIL, PLECS RT Box), and SiC/GaN semiconductor experience.
