Manufacturing Process Engineer - Quality

Hysata is an Australian green hydrogen technology company headquartered in Wollongong, New South Wales, that designs and manufactures high-efficiency electrolysers for the production of green hydrogen. The company's core mission is to accelerate the decarbonisation of hard-to-abate sectors by making green hydrogen economically competitive through a step-change improvement in electrolyser efficiency and system design. Hysata's electrolysers achieve a world-leading 95% system efficiency, equivalent to 41.5 kWh per kilogram of hydrogen, which surpasses the International Renewable Energy Agency's 2050 efficiency target and has been validated through publication in the peer-reviewed journal Nature Communications. Hysata's technology is distinguished by a drastically simplified balance of plant, modular architecture, and a design philosophy optimised for mass manufacturing, all of which contribute to delivering the lowest Levelised Cost of Hydrogen (LCOH) for customers. The company offers a turn-key electrolyser solution intended to transform the economics of green hydrogen production globally. Backed by leading strategic and financial investors, Hysata is scaling rapidly toward multi-gigawatt manufacturing capacity. The company has secured notable partnerships and commercial agreements, including deals with ACWA Power and POSCO Holdings, and has received support through Australia's Hydrogen Headstart funding programme. Hysata has also been recognised for its workplace culture, winning a Best Startup Culture award in 2024, and continues to engage with policymakers and international stakeholders to advance the green hydrogen industry.

About the role

Hysata is an electrolyser company moving from pilot-scale to sustained manufacturing, and we are building our Quality function. This is a hands-on Manufacturing Process Engineer role with a quality focus. The mission is simple: find quality problems early, lead the root cause analysis, and implement durable solutions at pace – across our in-house processes, suppliers, and testing. You will report to the Manufacturing Manager and work directly with team leads, operators and engineers on the floor. On-site in Australia, with potential for some supplier travel.

The Mission

• Detect – quality problems early through inspection, data, and floor presence – before they reach the next operation;
• Diagnose – lead structured root cause analysis (RCA – 5 Whys, Fishbone, 8D) to true root cause, using evidence not assumption; and
• Resolve – design, trial, and embed corrective and preventive actions that hold, then verify they worked.

Role responsibilities

• Own inspection strategy and acceptance criteria across cell material fabrication (coatings, substrates, treatments), cell assembly, and stack operations – catching defects at the earliest, cheapest point;
• Lead RCA on non-conformances, yield loss, and customer issues; drive corrective and preventive actions (CAPA) to closure and verify they hold;
• Improve process capability through error-proofing, parameter control, and basic SPC; convert see-and-fix cycles into permanent process and design improvements;
• Manage supplier quality – incoming inspection, non-conformances, and documentation (CoC, inspection reports, traceability);
• Maintain QMS records, change control, and CAPAs so quality data is trusted and audit ready; and
• Train operators and champion a right-first-time mindset – fixing the process, not assigning blame.

 What you'll bring

• Ability to work efficiently and effectively in a faced paced environment where everyday presents a new challenge;
• Degree, diploma, or trade qualification in engineering, materials science, chemistry, manufacturing, or related;
• 3–7+ years in a manufacturing process or quality engineering role, with a track record of solving real production problems;
• Hands-on with RCA (5 Whys, Fishbone, 8D), non-conformance management, and process improvement;
• Comfortable on the floor, biased to action, calm under pressure, and solutions-focused; and
• Desirable: electrolysers, fuel cells, or hydrogen tech; ISO 9001; SPC or data analysis; startup or scale-up experience.

What success looks like (First 12–18 Months)

• Problems detected earlier and resolved faster, with shorter see-and-fix cycles;
• RCA is rigorous and data-led; corrective actions hold and recurrence drops;
• Yield improves and rework falls as fixes move from temporary to permanent; and
• Production sees quality as a practical engineering partner, not a bureaucratic gate.

Why join us

• Build a Quality department from the ground up;
• Direct impact on commercial electrolyser deployment; and
• Work at the intersection of clean energy, manufacturing, and scale-up.

What we offer

• Idyllic beachside location;
• Stock options;
• Salary Sacrifice into Superannuation;
• Flexible working conditions;
• Recognition of Service;
• Wellness Allowance;
• EAP through Sonder;
• Novated Leasing;
• Employee discount program through Flare; and
• Awesome work environment and a pretty cool team!
