Stack Assembly Technician

Hysata is on a mission to accelerate the shift from fossil fuels to green hydrogen with the world’s most efficient electrolyser. Our breakthrough capillary-fed electrolyser achieves an unprecedented 95% system efficiency (41.5 kWh/kg) – a step change from incumbent technologies, which typically sit at ~75% and already ahead of International Renewable Energy Agency’s 2050 target. This leap in performance enables a radically simpler system design, slashing both energy use (opex) and system and renewables capex.

Hysata’s innovation has captured global attention, including publication in Nature Communications and support from leading strategic and financial investors such as bp, POSCO and Vestas. With over 100 team members, we’re a high-performing, purpose-driven company, proud to be 35% women, representing 20+ nationalities, and united by a shared mission to enable the decarbonisation of hard-to-abate sectors such as steel, chemical manufacturing, shipping and aviation.

Having secured Australia’s largest ever cleantech Series B raise of US$111 million, Hysata is scaling rapidly to bring our technology to market. With strong customer demand and a clear path to manufacturing at scale, we are on track to become a global leader in green hydrogen and put a major dent in global emissions.
