Lead Hardware Engineer — Powerwall

About Arkahub:Arkahub is a full-stack home energy company building consumer-grade energy products designed specifically for Indian households. We believe the Indian home deserves energy solutions engineered for how Indian grids actually behave not adapted from hardware designed for stable European or American infrastructure. Our platform enables households to generate, store, and intelligently manage power through a single system: one that handles the complexity of unreliable grids, volatile tariffs, and rising appliance loads so the homeowner doesnt have to. Over time, this intelligence compounds homes that run on Arkahub can automatically optimise electricity costs as time-of-day pricing expands, protect appliances from the voltage swings that damage modern electronics, and participate in emerging energy networks that turn every connected home into a node in a smarter, cleaner grid. Were building the platform that turns residential energy from a grudge purchase into a product you trust for 25 years. Backed by KAE Capital, Sparrow Capital, and Antler.

What Youll Own

Own the technical direction of Arkahubs core power conversion hardware from topology selection through to production-ready schematics, working directly with the founding team

Design the grid-tied inverter stage: multi-level power conversion, output filter, and grid interface circuits engineered for Indian voltage and frequency conditions

Architect the seamless backup and power conditioning system that lets households ride through outages and voltage events without noticing

Define subsystem interface specifications and work with external design partners on isolated DC-DC and solar input stages; review and validate partner deliverables

Own the thermal architecture: ensure the product operates reliably at Indian rooftop ambient temperatures across a 15-year service life

Design the protection and safety architecture: overcurrent, overvoltage, ground fault detection, surge protection, and anti-islanding all compliant with Indian standards

Drive the product through BIS certification and pre-compliance, coordinating with test labs and regulatory bodies

Engage semiconductor vendor FAE teams to optimise component selection and power stage performance
