Mechanical Design Engineer Location: Belfast Contract Type: Full-Time, Permanent Salary: Excellent Package Exceptional Benefits A fantastic opportunity has become available for a talented Mechanical Engineer to join a cutting-edge engineering organisation leading the way in zero-emission propulsion and next-generation clean technology. In this highly technical, hands-on role, you'll work on innovative projects that are shaping the future of sustainable propulsion systems. As part of a multidisciplinary engineering team, you will contribute to the design and integration of high-performance mechanical solutions for advanced products and technology platforms. The Role Reporting to the Head of Propulsion, the Mechanical Design Engineer will support the full lifecycle of advanced propulsion systems-from concept development and modelling through to testing, validation, and production. You'll work on sophisticated electro-mechanical assemblies incorporating energy storage, power distribution, and alternative fuel technologies. This role offers the chance to work in a dynamic, fast-growing business, contributing to world-leading engineering that is accelerating the shift to clean, sustainable propulsion. Key Responsibilities Develop and engineer precision mechanical components and assemblies using 3D CAD (CATIA or similar). Contribute to system-level design and integration for propulsion and energy platforms. Select materials, surface treatments, and tolerances appropriate for harsh marine or industrial environments. Produce detailed engineering drawings, BOMs, and documentation for manufacture. Apply first-principles mechanical engineering to validate and refine design concepts. Optimise designs for weight, performance, durability, and manufacturability. Participate in design reviews, testing, and validation activities to meet quality and certification requirements. Work closely with electrical, testing, and manufacturing teams to ensure seamless system integration. Support continuous improvement by introducing new tools, technologies, and design methods. About You Essential: Degree in Mechanical Engineering, Aerospace, Automotive, or related discipline (2:1 or above), or HND with significant industry experience. At least 3 years' experience in motorsport, aerospace, or advanced precision manufacturing. Strong knowledge of mechanical design principles, materials, and manufacturing processes. Proficiency in 3D CAD (CATIA V5/V6 preferred). Experience with prototype development, testing, or validation activities. Ability to take ideas from concept through to production-ready design. Strong communication, teamwork, and organisational skills. Able to perform in a fast-moving, technically challenging environment. Desirable: Experience with EDUs, engines, or complex mechanical systems.
