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 doesn’t 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. We’re 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 You’ll Own •

Own the technical direction of Arkahub’s 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 What You Bring •

8–10 years in power electronics hardware design, with 3+ years on grid-connected inverters (solar, UPS, energy storage, or motor drives with grid interface) •

Hands-on experience with multi-level inverter topologies and neutral-point management •

Designed and brought to production at least one product with grid-side output filtering (LCL, LC, or equivalent) •

Experience with Indian or international certification for power electronics (BIS IS 16221, IEC 62109, or equivalent) •

Proficient with Altium Designer, power simulation tools (PLECS, LTspice, or equivalent), and magnetics design fundamentals •

Comfortable working across the full hardware lifecycle: concept → schematic → layout review → bring-up → characterisation → production transfer Bonus Points •

Experience designing inverters, energy storage systems, or EV chargers for the Indian grid •

Familiarity with Indian grid realities: wide voltage range, neutral-earth voltage, DG synchronisation, capacitor bank transients •

Wide-bandgap semiconductor experience (GaN, SiC) and EMC debugging skills
