Growth Plans: Not only are we established but we also have huge growth plans for 2026 and although the team is a flat structure, we hope you would be able to become a team leader! About the role: We are looking for a Senior Mechanical Engineer within the Products division, you will join a team passionate about pushing the boundaries of engineering to develop the next generation of onsite safety & monitoring equipment, which are deployed in extreme environments. This role is challenging intellectually as the product and technology is innovative and groundbreaking and therefore you need to be a critical thinker You will be expected to independently drive design projects, apply sound engineering judgement, and provide technical oversight across development and sustaining activities. This position combines hands-on design with system-level thinking—supporting both new product development, optimisation, and iteration of existing concepts. You will take a leading role in refining product designs, resolving complex technical challenges, and ensuring design outputs meet the reliability, safety, and manufacturability standards required by the Energy sector. Key Responsibilities: * Lead full-cycle design: requirements capture, CAD modelling, calculations, tolerance analysis * Prototype, assemble, and validate performance * Oversee qualification testing for environmental and field compliance * Manage BOMs, ECNs, QA records, and specifications in line with QMS * Ensure adherence to industry standards and internal processes * Drive design improvements based on field feedback and production issues * Conduct structured root-cause analysis and implement corrective actions * Liaise with electronics, software, production, and sales teams * Provide technical input to customer queries, proposals, and tenders * Mentor junior engineers and contribute to design reviews * Promote a culture of professionalism, flexibility, and high standards Required skills: * A minimum of 8 years’ industry experience post-graduation as this is high tech and complicated technology * A 2:1 or higher BEng/MEng degree in in Mechanical, Aerospace, Automotive, Aeronautical or Mechatronics Engineering. * Fluency with 3D CAD tools (preferably Autodesk Inventor). * Engineering calculations including pressure containment, mechanical strength, and thermal performance * A proactive attitude with the ability to self-manage and lead without needing instruction * Experience managing technical documenta on and change control in a PLM system.
