Mecwin Group is a high-growth Indian motor and motion systems company supplying BLDC, PMSM, and induction motors across industrial, EV, and defence sectors. As motor technology at Mecwin advances, in-house drive development has become a strategic imperative — our motors deserve drives that are engineered by people who understand both the machine and the power electronics that runs it.

We are building our drives capability from the ground up and we need someone who has done exactly this before. This is not a role for a candidate who has only designed sub-systems or worked in support roles. We need a practitioner who has conceived, designed, verified, and shipped complete motor drive products.

You will own end-to-end development of motor drive systems for BLDC, PMSM, and Induction motors across a power range of 50 W to 50 kW (with a roadmap to higher power). This spans gate-driver and inverter hardware, DSP/microcontroller firmware, control algorithms, protection logic, thermal management, EMC/EMI compliance, and customer-level application tuning. You will simultaneously lead a small engineering team and be hands-on on the bench and in the lab.

•      Design three-phase and single-phase inverter stages using IGBTs, MOSFETs (SiC/GaN considered) for 50 W to 50 kW power levels

•      Design gate driver circuits, isolated power supplies, bootstrap circuits, and snubbers

•      Design DC bus capacitor banks, EMI filters, inrush limiters, and pre-charge circuits

•      Develop PCB layouts optimised for low stray inductance, thermal management, and creepage / clearance compliance (IEC 60664, UL standards)

•      Specify, evaluate, and qualify power semiconductors, magnetics, and passive components from vendors

•      Perform loss calculations, thermal modelling, and heatsink / cold-plate design for continuous and peak power ratings

•      Implement Field Oriented Control (FOC) for PMSM and BLDC; V/Hz, Direct Torque Control (DTC) for induction motors

•      Write production-grade embedded C firmware on DSPs (TI C2000 series preferred) and ARM Cortex-M MCUs (STM32, NXP)

•      Develop motor parameter estimation routines (offline and online) — Rs, Ld, Lq, flux linkage, rotor time constant

•      Implement sensorless control (back-EMF, MRAS, HF injection) as well as encoder/resolver/Hall-sensor-based position feedback

•      Tune current PI loops, speed loops, position loops for fast dynamic response and stability across load and temperature

•      Develop active protection algorithms — overcurrent, overvoltage, undervoltage, thermal derating, short-circuit, motor stall, and ground fault

•      Implement CAN, CANopen, Modbus RTU/TCP, RS485, and customer-specified communication protocols

•      Use real-time operating systems (FreeRTOS, SAFERTOS) and bare-metal architectures as required

•      Develop DVP (Design Verification Plan) and drive test procedures covering full load, overload, temperature, and fault injection

•      Conduct EMC pre-compliance testing (conducted emissions, radiated emissions, ESD, burst/surge) and coordinate with accredited labs for formal certification (CE, BIS, MIL-STD-461 as applicable)

•      Perform HIL (Hardware-in-the-Loop) and dynamometer testing for automotive and industrial applications

•      Support DFMEA, design reviews, and root cause analysis of field failures

•      Industrial: pumps, fans, compressors, conveyors, servo positioning systems — targeting IEC / CE compliance

•      Automotive / EV: traction drives, auxiliary drives (EPS, HVAC compressor, oil pump) — targeting AEC-Q100/Q200, IATF 16949 environment

•      Defence: brushless servo drives and actuator drives — targeting MIL-STD-810, MIL-STD-461 and ruggedised enclosure requirements

•      Lead and mentor a team of 3–8 hardware, firmware, and validation engineers

•      Own drive project plans, technical milestones, BOM cost targets, and prototype-to-production timelines

•      Interface with motor design, mechanical, and sales teams to align drive specifications with motor and application requirements

•      Manage sub-contractors, test houses, and component vendors

Competency Area

What We Expect to See

Power Topology

Voltage source inverters, active front end, Z-source; experience with SiC or GaN a strong plus

Motor Types

Demonstrated hardware + firmware delivery for BLDC, PMSM, and induction motors — all three

Control Theory

Solid grounding in state-space, frequency domain, and discrete control; able to tune without relying solely on auto-tune tools

PCB Design

4–6 layer mixed-signal PCBs; high-current power planes; differential pair routing; IPC-2221 familiarity

DSP / MCU

TI C2000 (F28x series) or equivalent; clock management, ADC synchronisation, PWM deadtime programming

Simulation Tools

MATLAB/Simulink (PLECS, SPS), LTspice or PSIM for circuit-level simulation; Altium or KiCad for PCB

Standards

IEC 61800, ISO 26262 (awareness), MIL-STD awareness; EMC CISPR 11/32, IEC 61000 series

Measurement & Debug

Oscilloscope, power analyser, current probe, LCR meter, dynamometer; JTAG/SWD debugging

This is a practitioner role. We are not hiring a theorist or a system architect who delegates all bench work. The right candidate will tick most of the following:

•      8–10 years of hands-on motor drive development experience (not system-level project management alone)

•      Has personally designed and built at least 2–3 complete motor drive products — from blank schematic to production release

•      Has worked across at least two of the three sectors: industrial, automotive, or defence — understands the different quality, certification, and documentation expectations of each

•      Has delivered drives across a wide power range — not just low power (sub-1 kW) and not just high power; breadth matters

•      Has personally written and debugged FOC firmware — not just integrated a library

•      Has experience handling real application problems: motor hunting, resonance, de-tuning at temperature, regenerative braking, inrush on start-up

•      Track record of on-time delivery and design-to-cost discipline

•      Can write clear technical documentation — specifications, test reports, application notes — to a professional standard

To protect the time of both parties, please do not apply if:

•      Your experience is limited to evaluation boards, university projects, or technology demonstrations that never reached production

•      You have only worked on drives above 100 kW (utility / large industrial) and have no experience with the sub-10 kW range

•      Your firmware experience is limited to configuring vendor stacks without understanding the underlying control algorithms

•      You have not worked on hardware yourself — purely firmware or purely hardware profiles are not suitable for this role

•      You are a fresh graduate or have fewer than 6 years of direct drive experience

•      Experience with ISO 26262 functional safety for automotive drives

•      Familiarity with AUTOSAR or automotive ECU development environments

•      Experience with resolver interface ICs and multi-turn absolute encoders

•      Knowledge of battery management systems and bidirectional DC-DC converters

•      Exposure to regenerative braking and active front-end rectifiers

•      Prior experience at a motor manufacturer or a drive OEM (not just a system integrator)

•      Patent filings or published technical papers in power electronics or motor control

•      Ownership of a full product line — you will not be a cog in a large engineering department

•      Well-equipped lab: dynamometers, power analysers, HIL rig, thermal chamber, EMC pre-compliance setup

•      Access to Mecwin's motor range for integrated testing — you work directly with the machine you are controlling

•      Cross-sector exposure: industrial, EV, and defence projects running simultaneously

•      Direct visibility with company leadership and influence on product roadmap

•      Competitive salary benchmarked to market; performance-linked variable component

•      Health insurance, gratuity, and statutory benefits as per applicable law

•      Relocation support for outstation candidates joining from outside Bengaluru
