Motor Control Firmware Engineer (Chennai)

Who Are We Raptee Energy is a full- stack electric motorcycle startup with a very solid technical moat, founded in 2019 by four engineers from Chennai (Ex Tesla, Wipro), working on bringing a no-compromise upgrade motorcycle to an otherwise scooter- only EV market. Raptee is incubated at CIIC & ARAI. Role Overview You will own the design, implementation, and validation of real-time motor control firmware for PMSM/IPMSM drives in EV power-train systems. Working across the full stack from control algorithm to hardware bring-up you will collaborate with controls, power electronics, and vehicle integration teams to deliver production-quality embedded software. What Youll Do - Develop and tune FOC algorithms: current regulation, MTPA, field weakening, and regenerative braking. - Implement SVM, PWM generation, and voltage limiting logic in embedded C for ARM Cortex-M targets. - Build and validate motor control models in MATLAB/Simulink; generate and verify production C code. - Integrate ADC-based current sensing, handle phase reconstruction, and calibrate sensor offsets. - Characterize and validate drive behavior across the full operating envelope on bench and motor Dyno. - Collaborate with hardware teams on inverter bring-up, gate driver integration, and fault protection. - Support vehicle-level integration: torque arbitration, state machine design, and diagnostics. Who Can Apply - 35+ years of hands-on motor control firmware experience with PMSM or BLDC drives. - Deep knowledge of FOC: Clarke/Park transforms, synchronous-frame PI control, and SVM. - Strong embedded C skills on ARM Cortex-M; comfortable with interrupt-driven, real-time architectures. - Experience with MATLAB/Simulink model-based design and embedded code generation. - Familiarity with ADC current sensing, real-time filtering, and signal conditioning. - Hands-on with oscilloscopes, runtime monitoring tools, and systematic firmware debugging. - B.E. / B.Tech or higher in Electrical, Electronics, or a related engineering discipline. Good To Haves - Experience with IPMSM saliency, reluctance torque exploitation, or MTPV operation. - Prior work on field weakening or regenerative braking in a production or near-production context. - Exposure to ISO 26262, MISRA-C, or automotive software quality processes. - Knowledge of EV power-train architecture, HIL simulation, or AUTOSAR.
