Technical Co-founder

Technical Co-Founder (Generator & Electric Machine Design, Wind)

Company: Recharga Chargine Pvt. Ltd. — Jaipur, Rajasthan (DPIIT-recognised deep-tech clean-energy startup)

Role: Technical Co-Founder / Chief Technical Officer

Commitment: Full-time, long-term. Equity-first with co-inventor IP credit.

About us

We're building the RADAX™ Generator — a patent-pending modular hybrid axial-radial flux permanent-magnet direct-drive architecture for wind turbines. Our business is B2B IP licensing to wind turbine OEMs worldwide, with later expansion into hydro generation and hybrid-vehicle alternators. We're at working-prototype design stage, moving from simulation toward a physical prototype.

The role

You will own and lead the entire technical side of the company — architecture, electromagnetic and mechanical design, simulation, prototyping, and the technical roadmap through to OEM validation. This is the single most senior engineering seat in the company. You set technical direction; you are not asked to carry any commercial, fundraising, or business-development load — that stays with the founding/commercial team. Your job is to make the machine real and make it best-in-class.

You'll be responsible for

• Owning the full generator design: electromagnetic (PM machine) design plus the mechanical/structural design of a direct-drive architecture.
• Leading FEA/simulation work (ANSYS Maxwell / Motor-CAD) and resolving hard multi-physics problems — including electromagnetic cross-coupling and BEMF behaviour in a combined axial-radial topology.
• Driving the path from TRL 5 toward a validated prototype (TRL 7).
• Building and leading a small engineering team over time.
• Being a named co-inventor and technical authority in OEM and investor conversations.

Must-haves

• Deep, demonstrable expertise in both electrical machine design (permanent-magnet synchronous generators; axial and/or radial flux) and mechanical/structural engineering of rotating machines.
• Hands-on generator design experience — not adjacent motor/EV work only.
• Working knowledge of the wind turbine market, drivetrains, and what OEMs actually specify and buy.
• Fluency with EM simulation tools (ANSYS Maxwell, Motor-CAD, or equivalent) and structural FEA.
• A track record of taking a design from concept to physical hardware.

Nice-to-haves

• Direct-drive PMSG experience specifically.
• Patents / published IP as inventor.
• Exposure to manufacturability and OEM qualification processes.

What we offer

• Founding-level equity and named co-inventor status on core IP.
• Full ownership and autonomy over the technical domain.
• A genuine deep-tech problem with global licensing upside.
• (Cash compensation is limited pre-funding and scales after our seed/pre-Series A round — we're upfront about that.)

This role is NOT for you if

You're optimising for near-term salary, a stable corporate seat, or a short engagement. We want a builder who's in it for years and thinks in terms of what RADAX becomes, not this quarter.
