Job description

NPD Intern — BESS (Battery Energy Storage System)

0-1

Full-Time

Greetings from Frigate Engineering Services Pvt Ltd ,Trichy

As an intern you will directly report to Founder & CEO

Frigate is a manufacturing execution platform connecting global buyers with Indian manufacturers, across machining, sheet metal, casting, and electronics. This role is a new build, not a slot in an existing team.

About the role

Frigate is developing a containerized BESS product from the ground up, and you'll own the New Product Development work on it end to end, working directly with the Founder & CEO. This isn't a shadow internship. You're responsible for real deliverables — mechanical layout, vendor coordination, BOM, and prototype build — on a live product, not a training exercise.

What you'll work on

• Container/enclosure design: structural layout, weatherproofing, thermal management, rack mounting for battery modules
• Electrical systems integration: battery rack layout, BMS/PCS coordination, cabling and switchgear specification
• Thermal and fire safety: cooling system specification and safety-standard research (IEC/UL/BIS/CEA as applicable) — for a product category where getting this wrong isn't an option
• Vendor coordination: work directly with Frigate's fabrication, sheet metal, and electrical vendor network to source components and sub-assemblies
• BOM and costing: build and maintain a full bill of materials with vendor quotes
• Documentation: technical specs, design-review notes, DFM considerations
• Prototype build coordination and test planning

What we need

• Final-year student or recent graduate — Mechanical, Electrical, Electronics, or Energy Engineering
• Basic grounding in electrical/power systems, or the ability to pick it up fast
• Comfortable owning ambiguity and driving a workstream between check-ins — this is a 0-to-1 build, not a task list
• Based in or willing to relocate to Trichy
• Prior exposure to battery systems, EV powertrains, or renewable energy (academic projects, EV competitions like SAE/Formula Student, prior internships)
• Any hands-on fabrication, prototyping, or vendor-facing experience

What you get

• Direct, regular working access to the Founder & CEO, not a manager three levels down
• Ownership of a real product from concept, not observation
• Exposure to Frigate's full vendor network across machining, sheet metal, casting, and electrical — a view very few interns get this early
• Strong performers will be considered for a full-time NPM role
