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-efficient with every iteration.

What You’ll Own
- Mechanical architecture of Cosy’s farming units
- 3D modelling, assemblies and production drawings in SolidWorks




- 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
