About

Mechanical Design Engineer with 9 years of experience spanning metal casting, machining, tooling (die/mold design), special-purpose machine (SPM) design, sheet-metal enclosures, and structural systems. Combines hands-on fabrication and manufacturing knowledge with CAD automation (iLogic, configurators) and simulation (MAGMASOFT casting simulation, Inventor-based FEA validation) to take designs from concept through commissioning. Independently designed and built a working 3D printer from scratch.

Experience

Mechanical Design Engineer II Hubbell India Pvt Ltd · Full-time Apr 2022 – Present 4 yrs 4 mos Chennai, TN, India Own end-to-end engineering for network/server cabinets, wall-mount enclosures, cable organizers, and commercial-grade cabinets across 5 product lines, maintaining full UL testing compliance. Ran full-cycle product development (scope, concept design, DFMA, FEA validation, prototyping, documentation, deployment), including simulating UL wall-mount cabinet load tests in Autodesk Inventor at 2x rated load. Rebuilt legacy CAD assets as configurable Inventor iParts/iLogic models, cutting new-variant turnaround from weeks to a single day and supporting 100+ active configurations. Redesigned next-gen residential plugs, connectors, and receptacles, cutting part count from 13 to 6 and insertion force by half while passing all UL load testing. Modeled injection-molded components with verified assembly ahead of tooling release. Adapted platforms into bespoke cabinet solutions across 30 key customer requirements and managed sustaining Engineering Change (EC) activity.
Assistant Engineer I Evoqua Water Technologies LLC · Full-time Mar 2021 – Apr 2022 1 yrs 1 mos Chennai, TN, India Produced detailed 2D General Arrangement (GA) drawings for Bio Process systems, holding 95% first-pass accuracy against spec. Designed structural components (piers, cages, trusses, platforms, tank weldment assemblies) for circular process tanks spanning 60-150 ft diameter, building a configurator model with parametric drawings that auto-update from the 3D model to automate custom truss/scraper sizing. Built parent configurator models (sketch parameters + iLogic) that standardized structural assembly design, cutting model turnaround to roughly a third of the previous baseline. Generated preliminary BOMs from 2D GAs for early-stage cost estimation. Cross-checked civil drawings and spec sheets against preliminary layouts, catching missing or ambiguous dimensions. Implemented ECNs/DCNs, rebuilding non-parametric legacy 2D drawings and STEP files into parametric CAD models.
Mechanical Design Engineer Autotech Industries India Pvt Ltd · Full-time Feb 2018 – Mar 2021 3 yrs 1 mos Chennai, TN, India Casting, Tooling & Machining Development: Directed full-cycle technical work (pattern design, CNC programming, casting machining, precision fixture development, SPM engineering). Programmed casting patterns in Mastercam for VMC machining, selecting tooling and feed/speed sequences. Insourced mold and die tooling development, leading a 3-member CNC team, cutting mold/die costs by 50% and design-to-production turnaround from a month to 2 weeks. Applied MAGMASOFT casting simulation to eliminate shrinkage, porosity, pinhole, and misrun defects, improving first-pass yield by 50%. Conceptualized, designed, and commissioned SPMs for multi-head spindle drilling and valve guide lapping, doubling production capacity. Engine & Power Systems Development: Engineered 5kVA/7.5kVA genset enclosures, reducing noise from 90 dB to 72 dB. Designed diesel-engine speed governors for agricultural pumps. Converted a 5HP air-cooled engine into a 7.5HP water-cooled genset engine, validated through 200 hours of full-load endurance testing, extending service life by 25%. Developed NVH mitigation systems cutting operational noise and vibration by 25%.
