Senior Mechanical Design Engineer

Job description

Senior Mechanical Design Engineer Dunfermline Permanent ABOUT US When a five-year-old boy was blinded after a regular eye exam failed to spot a retinal detachment, his father made it his life’s work to help eye care professionals by revolutionising retinal imaging. Optos was founded by Douglas Anderson in 1992 with the goal to make a patient-friendly device to quickly capture the entire retina. The experience of Douglas Anderson is a thread that runs through the company to this day and has resulted in our products being used in nearly 20,000 locations globally. Optomap® shows up to 82% (200°) of the retina in a single-capture, offering unrivalled clarity and Optos is proud to be recognised as the leader in this field. ROLE SUMMARY We are seeking a talented Senior Mechanical Design Engineer to join our Optomechanical team within the Research and Development department, based in Dunfermline. In this role, you will play a key part in designing and developing advanced optomechanical systems that underpin both our next‑generation retinal imaging products and improvements to our existing portfolio. You will contribute to concept development, detailed design, prototyping, and validation, working closely with cross‑functional teams to bring innovative, high‑performance solutions from idea to implementation. ESSENTIAL DUTIES AND RESPONSIBILITIES Lead concept development, system‑level design, and delivery of mechanical solutions. Develop innovative designs to solve complex engineering challenges. Produce, review, and approve drawings, BOMs, and documentation in line with PLM processes. Manage small projects, ensuring effective planning and on‑time delivery. Drive continuous improvement across product designs and engineering practices. Support prototype build, testing, and transition into product and clinical environments. Analyse and report experimental and verification results to guide design decisions. Apply advanced CAD techniques, GD&T, and tolerance analysis to ensure robust designs. Lead design reviews, FMEA, verification testing, and compliance activities. Interpret and validate simulation results and support design optimisation. Conduct root‑cause analysis and implement corrective actions for complex issues. Select materials and apply DFM principles across multiple manufacturing methods. Ensure adherence to design control, regulatory requirements, and quality standards. Contribute to patents, disclosures, and technical publications. Collaborate with suppliers and support supply‑chain decisions. Mentor junior engineers and promote best‑practice design and analysis techniques. MINIMUM QUALIFICATIONS Degree‑level education in mechanical engineering, optomechanical engineering, or equivalent professional experience. Extensive experience in mechanical design, including delivery of complex, multi‑component systems. Proven experience in the design and integration of motors and precision motion systems within complex mechanical assemblies Advanced proficiency in CAD, GD&T, tolerance analysis, and PLM‑based documentation control. Experience interpreting simulation results and applying DFM principles across multiple manufacturing methods. Strong experience in resolving complex thermal management challenges, including the use of simulation tools to evaluate and optimise system performance. Strong leadership and mentoring skills, with the ability to guide junior engineers and influence technical direction. Proven ability to manage small projects, prioritise effectively, and deliver high‑quality outputs to tight deadlines. Demonstrated capability in root‑cause analysis, verification testing, and compliance with design control requirements.
