Senior Mechanical Engineer
Location: High Wycombe, Buckinghamshire, UK
Job ID: REQ-056607
Overview
The Senior Mechanical Design Engineer is a key contributor to the design, development, and validation of complex electro-mechanical and opto-mechanical systems for next-generation analytical instrumentation. The role provides technical input across the full product lifecycle, from concept through production, ensuring mechanical solutions meet performance, thermal stability, reliability, and manufacturability requirements.
Responsibilities
* Develop mechanical concepts for precision analytical instrumentation, including opto-mechanical design, precision motion mechanisms, structures, and thermal management.
* Define mechanical architectures to meet performance requirements for stiffness, thermal stability, vibration control, and serviceability.
* Collaborate with systems, optics, electronics, and firmware engineers to define interfaces, packaging, and system trade-offs.
* Produce detailed mechanical designs using SolidWorks or equivalent, including 3D models and 2D manufacturing drawings.
* Integrate electronics, PCBs, cabling, sensors, and optical components within constrained mechanical envelopes.
* Apply GD&T and tolerance analysis to control critical interfaces and ensure precision and interchangeability.
* Select appropriate materials and finishes to meet structural, thermal, environmental, and manufacturability requirements.
* Apply FMEA and participate in peer design reviews to identify potential failure modes and implement mitigation actions.
* Design for manufacturability, assembly, test, service, and cost in line with right-first-time principles.
* Perform engineering analysis, including hand calculations and FEA (structural, modal, thermal), to validate design performance and reduce risk.
* Support prototype builds and verification testing.
* Support transfer of designs to manufacturing, including BOM creation, drawing release, and change control.
* Define and support assembly processes, tooling, and fixtures in collaboration with manufacturing.
Required
* Bachelor’s degree required in Mechanical Engineering or a closely related discipline
* Minimum of 7+ years of recent design engineering experience in a high-technology environment (preferably scientific instrumentation, medical devices, or aerospace).
* Strong Physics Fundamentals and deep understanding of kinematics is essential for this product line.
* Proven track record in the design of complex mechanisms and enclosures involving mixed materials (machined metals, sheet metal, injection moulded plastics).
* Experience with Opto-Mechanical design: Mounting and adjusting optical components (lenses, mirrors, sensors) with high stability.
* Proficiency in 3D CAD modelling (SolidWorks preferred) and PDM systems.
* Strong knowledge of manufacturing processes, surface finishes, and coating technologies.
* Hands-on experience in prototyping, assembly, and testing of mechanical systems.
Desirable
* Experience designing for EMC to protect sensitive internal electronics.
* Knowledge of automation or robotics within an instrument (stepper motors, actuators).
* Familiarity with regulatory standards (e.g., UL, CE, RoHS) relevant to laboratory equipment.
* Experience designing Verification and Validation test for opto-mechanical assemblies.
* Awareness of design thinking methodology.
Preferred Characteristics
* Possessing a task- and goal-oriented mindset.
* Analytical thinking driven by data and physical principles.
* Ability to see both the small (micron-level tolerances) and the big picture (system architecture).
* Possessing strong organizational skills.
* Problem solving aptitude.
* Attention to detail.
* Adaptable to change.
