Product Design Engineer - Mechanical
Location: Mumbai, Goregoan East
Type: Full-time
Experience: 4–8 years
The Role
Cosy is building modular indoor farms designed to grow fresh produce directly where it is consumed.
We're looking for a Product Design Engineer who can take our current farm system and engineer its next generation - not simply make drawings.
You will own the mechanical evolution of the product from concept → CAD → prototype → testing → manufacturing → field feedback → redesign.
Your objective is straightforward but difficult:
Your mandate is to turn our current farm into a world-class, production-ready product - engineered for reliability, manufacturability, serviceability and scale, while achieving an aggressive cost structure suited to the Indian market.
The goal isn't simply to make the product work. It's to make it simpler, smarter, more robust and dramatically more cost-effective with every iteration.
What You'll Own
Mechanical architecture of Cosy's farming units
3 D modelling, assemblies and production drawings in Solid Works




Design for manufacturing and assembly (DFM/DFA)
Sheet-metal, fabricated structures, plastics, insulation/enclosures and other manufacturing processes
Mechanical integration of HVAC/cooling, water systems, pumps, tanks, lighting and electronics
Material selection, tolerances, fits and component specification
Prototype development and engineering validation
Design testing, failure analysis and iterative improvement
BOM simplification and aggressive cost engineering
Designing for reliability, cleaning, maintenance and serviceability
Technical coordination with fabricators and component vendors
Reviewing manufactured components against engineering drawings and specifications
Supporting installations and field troubleshooting when engineering involvement is required
Maintaining organised CAD, drawings, revisions and engineering documentation
What Good Looks Like
You don't just ask:
"Does it work?"
You ask:
Can it have fewer part
