About us
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.
About the role
We are seeking a Mechanical Engineer to join the Balance of Stack team, supporting end-to-end delivery of electrolyser systems including design, procurement, fabrication, construction and commissioning of our demonstration and commercial scale electrolyser plants. This role is central to growing our in-house capability across pressure equipment, rotating equipment, piping, materials selection and fabrication. You will thrive in the fast-paced start-up world where no two days are the same. You’ll be joining a team of smart, driven, collaborative and highly dedicated individuals who love solving engineering challenges and who are excited to be fighting the climate crisis. You’ll help translate breakthrough electrolyser technology into real-world industrial systems deployed at commercial scale.
Role responsibilities
Mechanical Design: Support the mechanical design of our electrolyser packages, including designing piping, pressure equipment, and selecting rotating equipment and materials. Work closely with the process engineering team and engineering service providers to ensure the mechanical design meets requirements for safety, reliability, efficiency and cost.
- Conduct 3D layout reviews, with an eye for process requirements, constructability, safe operability and maintenance.
- Generate conceptual 3D drawings to support decision making for product development
- Mark up and review piping isometrics and equipment general arrangement drawings, including verification of equipment against 3D layout, process requirements, and adequate piping and equipment support detailing;
- Review material and line specifications, pipework design and routing, and equipment layout; and
- Develop and review technical specifications and other engineering deliverables for the mechanical discipline.
Procurement: Coordinate procurement activities for mechanical equipment, piping and special items.
Construction and Fabrication:
- Establishing and maintaining pressure vessel and equipment registers;
- Leading P&ID walkthroughs with the construction team and contractors;
- Planning, witnessing and signing off pressure and leak tests;
- Performing as-built checks and updating drawings and registers; and
- Managing the flange register and joint integrity records.
Commissioning: Support commissioning of new electrolyser packages.
Continuous Improvement: Contribute to the continuous improvement of Hysata’s mechanical engineering capability, including:
- Refine technical specifications and other engineering documents such as piping material specification based on lessons learned from design, fabrication, operation and previous experience;
- Developing additional engineering documents such as technical bid evaluation process for mechanical equipment and piping packages.
What you'll bring
- A Mechanical Engineering degree;
- Experience in the design and fabrication of pressure vessels and/or process piping, ideally in the chemical, petrochemical, oil and gas, or hydrogen industries;
- Working knowledge of pressure equipment and piping codes such as AS 1210 (Pressure Vessels), AS 4041 (Pressure Piping) and/or ASME BPVC Section VIII and ASME B31.3;
- Experience with materials selection for process equipment in corrosive or demanding services;
- Proficiency in CAD and plant layout software commonly used in the industry (e.g. AutoCAD, AutoCAD Plant 3D, SolidWorks, or equivalent);
- Ability to read, mark up and review P&IDs, GAs and piping isometrics;
- Understanding of safety regulations and practices to ensure a safe working environment;
- Flexibility to handle unexpected challenges and adjust plans accordingly;
- Motivated, capable of working independently within a multi-disciplinary environment;
- Strong written and verbal communication skills; and
- Flexibility to travel and work from different locations to support construction and commissioning activities.
Valued skills
- Experience level 5+ years;
- Experience with hydrogen, oxygen or caustic process equipment;
- Experience with technical bid evaluation of mechanical equipment and piping packages;
- Site-based construction, fabrication or commissioning experience, including witnessing pressure and leak tests;
- Familiarity with piping isometric and spool fabrication processes;
- Exposure to hazardous area and dangerous goods requirements relevant to hydrogen plants.
