Fuse Energy is a forward-thinking renewable energy startup dedicated to transforming the global energy landscape through innovation and scalable infrastructure. We are seeking a skilled Mechanical Design Engineer with a strong background in mechanical engineering or a related field to support various projects across our EPC (Engineering, Procurement, Construction) and R&D teams. The ideal candidate will be responsible for combining robust 3D CAD skills with a practical, field- oriented approach- comfortable not only designing on a screen but also assembling and iterating on physical systems. This role involves working on first-of-a-kind R&D prototypes and pilot skids, including mechanical assembly, tubing runs (Swagelok or equivalent), and system integration.

Key Responsibilities

• Produce detailed 3D CAD models and mechanical drawings for systems, test stands, and both pilot- and large-scale builds.
• Support the R&D team by developing CAD models and fabrication-ready designs for first-of-a-kind concepts.
• Design and lay out piping, tubing, and mechanical components, ensuring performance, maintainability, and compliance.
• Assemble, test, and troubleshoot R&D and pilot skid systems in the field, including tubing fabrication (e.g., Swagelok) and hardware integration.
• Optimise system layouts, piping runs, and mechanical component placement to maximise performance, maintainability, and regulatory compliance.
• Coordinate with engineers, project managers, and suppliers to maintain clean, organised CAD files and documentation.
• Liaise with vendors and manufacturers to ensure feasibility, cost-efficiency, and manufacturability of designs.

• Bachelor’s or Master’s degree in Mechanical Engineering or a related discipline.
• 3+ years of experience in mechanical design, CAD modelling, and manufacturing support.
• Proficient in SolidWorks, Onshape, or equivalent CAD tools.
• Strong understanding of GD&T, Design for Manufacturing (DFM), and Design for Assembly (DFA).
• Comfortable with field work, including mechanical assembly, tubing bending, and on-site troubleshooting.
• Strong understanding of mechanical systems, piping layouts, structural supports, and equipment mounting.
• Solid grasp of mechanical systems, engineering design principles, and ISO standards.
• Detail-oriented, with strong problem-solving skills, clear communication, and an ability to thrive in a fast-paced environment.

Bonus

• Hands-on experience working with external suppliers and manufacturers.
• Exposure to pilot-scale process systems or test stands.
• Familiarity with piping design and fluid system layouts.
• Knowledge of FEA tools or mechanical simulation techniques.
• Background in scaling R&D concepts to production-grade systems.

• Competitive Salary
• Paid annual leave
• Supportive and collaborative engineering environment
• Opportunities to work on cutting-edge systems and innovative technology
