Pune, Maharashtra, India Kalbhorz Full time ₹ 12,00,000 - ₹ 36,00,000 per year


Hiring: Thermal Simulation Engineer – Electric Motors & Drives


Location:
Pune/Pimpri-Chinchwad, India (On-site)


Experience:
3–7 Years


Industry:
Electric Vehicles, Powertrains, Mobility Tech


About Us

At
Kalbhorz
, we're building next-generation
axial flux electric motors
and
integrated motor-drive systems
for high-performance mobility—ranging from electric two-wheelers and drones to EVs and marine applications. As we scale, we're seeking a driven
Thermal Simulation Engineer
to optimize our motor and drive platforms for high efficiency, reliability, and compactness.


Job Description

As a
Thermal Simulation Engineer
, you will be responsible for developing and validating detailed thermal models for electric motors, inverters, and motor controllers. You'll collaborate closely with design, hardware, and testing teams to simulate heat dissipation, cooling strategies, and thermal stress across real-world drive cycles.


Key Responsibilities

  • Develop thermal models of electric motors (axial flux, BLDC, SRM) and inverters using
    Ansys, COMSOL, or equivalent tools
    .
  • Simulate
    heat flow, cooling (liquid/air/natural convection)
    , and temperature rise in motor windings, cores, and power electronics.
  • Optimize
    thermal management strategies
    , including material selection and passive/active cooling methods.
  • Work with the mechanical team to integrate simulation results into
    enclosure/casing design
    .
  • Correlate thermal simulations with
    physical test results
    and iterate for accuracy.
  • Generate detailed
    thermal performance reports
    , design guidelines, and risk mitigation strategies.
  • Collaborate with cross-functional teams (electromagnetic, mechanical, PCB, controls) to co-develop robust systems.


Job Requirements

  • Bachelor's or Master's in Mechanical, Electrical, Thermal Engineering, or related fields.
  • 3–7 years of experience
    in thermal simulation and analysis, preferably in the
    EV, eMobility, or powertrain sector
    .
  • Proficiency in
    thermal FEA/CFD tools
    like
    Ansys Icepak, Fluent, COMSOL, FloTHERM, or Star CCM+
    .
  • Strong understanding of
    electric motor design
    , losses (copper, core, switching), and
    cooling systems
    .
  • Knowledge of
    power electronics packaging
    and thermal behavior of MOSFETs, IGBTs, SiC modules is a strong plus.
  • Ability to interpret drive cycles, duty loads, and usage scenarios into real-time simulation cases.
  • Hands-on experience with thermal testing and sensor integration is preferred.
  • Strong communication, documentation, and cross-team collaboration skills.


Nice to Have

  • Experience with
    Electric Motor
  • Exposure to
    automotive standards
    for thermal reliability and validation
  • Familiarity with
    system-level simulation tools
    (e.g., Simulink, Matlab, GT-Suite)
  • Previous work with
    liquid cooling loop design
    for compact electric drivetrains


What We Offer

  • Work on cutting-edge thermal challenges in
    next-gen EV powertrains
  • A high-impact role in a rapidly growing startup
  • Access to state-of-the-art labs, tools, and simulation resources
  • Competitive salary + ESOP + performance-linked bonus
  • Flat hierarchy, innovation-driven culture
