Job Description

Senior R&D Engineer – Contract (Outside IR35)

London | On-site | 6 months+

A growing diagnostics team are seeking experienced R&D Engineer's to support the design, prototyping, and testing of electro-mechanical systems for a next-gen diagnostic platform. This is a hands-on contract role suited to engineers with a strong background in mechanical systems, fluidics, and product development within regulated industries.

What you’ll be doing:

• Design, build, and test systems, sub-systems, and lab fixtures to meet evolving project requirements
• Lead experiments to optimise performance and troubleshoot technical challenges
• Analyse, interpret, and present experimental results clearly to technical and non-technical stakeholders
• Collaborate with cross-functional teams including software, electronics, IC design, and process engineering
• Support the development and testing of prototype instruments both in-house and with external partners
• Apply novel methods and creative thinking to solve complex electro-mechanical problems

What you’ll bring:

• A degree in Mechanical Engineering (or similar), with significant post-grad R&D experience
• Deep understanding of fluid dynamics, system mechanics, and basic electronics
• Skilled in CAD and CAE tools such as SolidWorks and COMSOL
• Familiarity with microfluidics, pneumatics, and thermal control systems
• Strong hands-on prototyping skills – e.g., CNC machining, 3D printing, plastics bonding
• Ability to make sound engineering decisions and communicate findings effectively

Bonus if you have:

• Experience designing sealed fluidic plastic parts
• Exposure to regulated environments (ISO 13485 )
• Programming experience or scripting knowledge for lab automation
• Track record of planning and conducting scientific experiments for process optimisation

This is a great opportunity for an Engineer who enjoys variety, autonomy, and working closely with other disciplines to get things moving from lab to product.
