Job Description
Job description
Who Are We
Raptee.HV is a full-stack electric motorcycle startup with a strong technical foundation. Founded in 2019 by four engineers from Chennai (with backgrounds at Tesla and Wipro), Raptee Energy aims to revolutionize the EV market by offering a high-performance motorcycle alternative to the existing scooter-dominated options. The company is incubated at CIIC & ARAI.
Why Join Us?
As a Hardware Engineer, you will own the schematic design, MCU selection, control analysis, and debugging of our PMSM motor controllers. From deriving PI gains mathematically, to designing circuits, to validating MTPA and field-weakening strategies on dyno, your work will directly shape the efficiency, drivability, and reliability of our motorcycles.
This role offers a unique chance to bridge theory and practice — combining advanced control mathematics, hardware design, and real-world validation — with your designs powering vehicles on the road.
Key Responsibilities
• Power Electronics & High-Voltage Hardware
• Design inverter stages, gate driver circuits, protection circuits, and sensing hardware for PMSM controllers.
• Select and validate semiconductors (MOSFETs, IGBTs, drivers, sensors) with attention to thermal and EMI/EMC constraints.
• Support EMI/EMC compliance and reliability engineering.
• Low-Voltage & Schematic-Level Design
• Create schematics for microcontroller circuits, decoupling, RC filters, and signal conditioning.
• Define best practices for analog vs digital ground separation, noise mitigation, and mixed-signal design.
• Provide clean schematic packages for PCB design engineers and review their implementation.
• Control Systems & Plant Modeling
• Develop mathematical plant models of inverter–motor systems using Laplace transforms and transfer functions.
• Perform stability analysis and analytically calculate PI/PID gains before dyno validation.
• Simulate and validate control loops in MATLAB/Simulink.
• Advanced PMSM Control Strategies
• Apply advanced PMSM/IPM control methods such as MTPA, MTPV/field weakening, and deep field weakening.
• Understand differences in strategy between surface PMSM and interior PMSM.
• Implement and validate smooth transitions between torque control, MTPA, and flux-weakening regions.
