Job Description: Mechanical Design Engineer – Power Electronics Systems
Company: Autodata Technologies Pvt. Ltd., Navi Mumbai Location: Navi Mumbai
(TTC Industrial Area) Experience: 3–8 years Qualification: B.E. / Diploma (Mechanical Engineering)
Role Overview
You will be responsible for the mechanical design, enclosure engineering, and
thermal management of high-power industrial electronic assemblies including IGBT
three-phase stacks, IGBT-based inverters (100–200 kW), and SMPS power supplies
for the electroplating and surface treatment industry.
Key Responsibilities
∙Mechanical design and 3D modelling of power electronics enclosures,
busbars, heatsink assemblies, and mounting structures using "Autocad, Solid Works, Krycad"
∙Thermal analysis and heat removal design — heatsink selection, forced air
cooling (fans, ducting), liquid cooling plates, and thermal interface material
(TIM) specification
∙Design of IGBT three-phase stack assemblies including clamping pressure,
isolation, busbar geometry, and creepage/clearance compliance per IEC
60664
∙Mechanical packaging of SMPS units for industrial environments — DIN rail,
19" rack, or custom enclosures
∙BOM preparation, vendor coordination for sheet metal fabrication, extrusions,
and machined parts
∙Review of manufacturing drawings, GD&T, and tolerance stack-up analysis
∙Coordination with electrical/electronics team for PCB mounting, connector
layouts, and cable management
∙Prototype build support and design iteration based on thermal test results
ust-Have Skills
∙Proficiency in Kryad mechanical design software (or KiCad for PCB
mechanical integration)
∙Demonstrated experience with thermal management — heatsink design,
CFD awareness, junction-to-ambient thermal resistance calculations
∙Experience with IGBT module mounting — torque specs, thermal compound
application, isolation pads (e.g., Keratherm, Bergquist)
∙Sheet metal design for fabrication (bending, punching, powder coating)
∙Familiarity with IP ratings (IP20 to IP54), EMC enclosure requirements, and
cable gland sizing
Good-to-Have
∙Exposure to electroplating rectifiers, CED paint shop equipment, or industrial
UPS/inverter systems
∙Knowledge of IEC 61439 (switchgear enclosure standard)
∙Experience with busbar design software or manual calculation of current
density and temperature rise
∙SolidWorks Simulation / ANSYS for basic thermal FEA
