About the role

We are seeking a high-performing Mechanical Design Engineer to develop polymer components within our hydrogen electrolyser cell and stack.

You will design, analyse, prototype and industrialise precision components operating in demanding electrochemical and fluid environments. Your work will directly influence system efficiency, reliability, manufacturability and cost. This is a hands-on, high-accountability role suited to engineers who thrive on solving complex physical problems and delivering prototype hardware into production. 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.

Role responsibilities

Component Ownership & Design

• Own components from concept through validation and production release to meet project deadlines;
• Create detailed 3D models and 2D drawings in NX and manage releases via Teamcenter PLM;
• Perform tolerance stack-ups and ensure robust mechanical integration;
• Design injection molded polymer parts for manufacture, assembly and cost, supporting scale-up to production; and
• Contribute to DFMEA, risk assessments and verification & validation planning.

Prototyping, Testing & Manufacturing

• Build and test prototype hardware to validate design intent;
• Work with our testing team to define test plans, analyse data, diagnose failure modes and iterate design improvements rapidly;
• Engage suppliers on manufacturing processes, tolerances and quality metrics; and
• Support transition from prototype to scaled production.

Collaboration

• Lead and participate in design reviews and technical workshops;
• Work closely with other engineers and stakeholders to ensure alignment on project goals and requirements;
• Communicate complex technical concepts clearly across engineering and non-technical teams; and
• Operate effectively in a fast-paced, evolving hardware development environment.

What you'll bring

• Bachelor’s degree in Mechanical Engineering or related discipline;
• 3–6+ years of experience delivering mechanical components into prototype and/or production environments;
• Strong proficiency in NX, SolidWorks or equivalent 3D CAD software;
• Experience with tolerance analysis, structural or fluid calculations, and failure investigations;
• Familiarity with requirements capture, DFMEA and structured Verification and Validation (V&V) processes;
• Hands-on prototyping and workshop experience.

Experience in one or more of the following is advantageous

• Injection-moulded polymer components;
• Elastomeric sealing systems;
• Microfluidics or precision assemblies;
• Pressurised fluid or electrochemical systems;
• Alkaline Electrolyser compatible or corrosion-resistant materials.
