Role Overview
As the Controls Engineer, you will serve as the technical leader for our power electronics control systems. Joining our multi-disciplinary engineering team, you will drive the modeling, development, and validation of advanced embedded controls for high-power solid-state converters and inverters. Your expertise will directly impact the reliability and efficiency of our medium-duty EV platform's charging and drivetrain systems.
Key Responsibilities
-
Lead the development and implementation of advanced control algorithms for high-power electronics, including AC-DC, DC-DC, AFE, and multi-level inverters.
-
Design model-based embedded control architectures using MATLAB/Simulink and validate them utilizing Typhoon HIL and real-time platforms.
-
Manage and oversee the firmware engineering lifecycle for power electronics, from C/C++ development to hardware-software integration.
-
Drive system reliability and quality improvements across solid-state converter designs utilizing Design for Six Sigma (DFSS) methodologies.
-
Collaborate with battery and integration teams to implement fast DC charging protocols (e.g., CCS, NACS) and ensure seamless BMS integration.
Required Skills & Experience
-
10+ years of experience in power electronics, solid-state converters, and embedded control systems.
-
Proficiency in model-based design (MATLAB/Simulink), HIL validation (Typhoon), and microcontroller programming (C/C++, TI C2000).
-
Strong understanding of high-power converter topologies (DAB, resonant converters) and advanced inverter control strategies.
-
Excellent technical leadership skills with a proven history of managing complex R&D projects and multi-disciplinary teams.
-
Master's or Ph.D. in Electrical Engineering, Power Electronics, or equivalent practical experience.
Preferred Qualifications
-
Experience working with megawatt-scale EV charging infrastructure and energy storage control systems.
-
