Mechanical Design Engineer

We’re looking for an experienced Mechanical Design Engineer with an instinct for precision mechatronic devices and automation systems with the pace to move from blank page to convincing concept quickly. You’ll play a key role in shaping robust, manufacturable designs for our robotic manufacturing system, and you’ll also help us explore and communicate how the system integrates into customer facilities.

This is a hands-on mechanical design role with real autonomy. You’ll take ownership of critical modules, and you’ll also support early-stage investigations into new customer layouts and integrations. That means creating concept models, prototype CAD layouts, and clear visuals that help teams align early and start projects faster, with fewer surprises later.

You’ll join a fast-growing, interdisciplinary team, working with people who love solving worthwhile problems and care about getting the details right. 

This role will be a full time on-site position at our campus in Melbourn.

What you’ll do:

• Own mechanical design of key modules, from concept through to detailed, manufacturable release.
• Quickly turn around concept models that integrate into existing facilities and or tools.
• Rapidly produce prototype CAD layouts, 3D renderings, and layout drawings for factory and cleanroom environments.
• Capture core integration requirements and turn them into clear material that supports further development.
• Provide content to support early-stage investigations into layouts for existing and new customers.
• Ensure concepts align with technical road maps across the engineering teams, helping speed up project start up.
• Work with prototyping companies to create realistic models where needed to support renders, layouts, and stakeholder conversations.
• Build tolerance analyses and use appropriate analytical techniques to support design choices and reduce risk early.
• Use tools such as FMEA to identify and mitigate technical risks, without slowing progress.
• Collaborate closely across mechanical, systems, software, electronics, and operations to land designs that are practical to build, test, maintain, and scale.

Qualifications

• Mechanical Engineering or a similar discipline, with relevant industrial experience (degree or vocational route).
• Proven, hands-on experience developing products and delivering them into manufacture.
• The ability to work within existing designs, rapidly pulling layouts and concepts together.
• Strong 3D CAD skills (ideally SolidWorks), and a track record of producing clear, useful outputs at pace.
• Experience creating prototype CAD layouts, integration concepts, and factory layout drawings that help teams make decisions.
• Deep experience of material and manufacturing method selection, and producing accurate technical documentation to BS8888 including GD&T’s.
• Confidence building tolerance analyses and using analytical techniques to support your design work.
• Understanding of GMP and clean room environments.
• Working knowledge of lab-based biological processing equipment is advantageous.
• A practical, risk-aware mindset, using approaches like FMEA to move quickly while staying disciplined.

Experience from medical devices, consumer products, automotive, aerospace, or digital printing can be a great fit, but what matters most is how you design, how you collaborate, and how you think.
