Job description

Lead Mechanical Design Engineer

Hertfordshire

Up to £80,000 DOE

Benefits - Include a C10% bonus, good holiday and pension contributions

I'm working on an opportunity for an experienced mechanical engineer to join an established engineering business in Hertfordshire, taking a senior technical role in the development of complex electromechanical products.

This is a hands‑on position for someone who can take ownership of mechanical design from initial concept through to prototyping, testing and manufacture, while providing technical guidance and support to a relatively junior engineering team.

You'll be involved across the product development lifecycle, combining detailed design work with engineering analysis, problem‑solving and technical decision‑making.

I'm particularly interested in speaking with engineers who have experience in:

• Mechanical design and product development, from concept through to production
• 3D CAD, detailed design and engineering drawings
• Hydraulics, pneumatics, valves, pressure systems or flow‑related equipment
• Engineering calculations, design analysis and validation
• Prototyping, hands‑on build, testing and fault‑finding
• Design for manufacture, including castings, machined components and fabricated parts
• Working with complex or high‑integrity mechanical products
• Technical leadership, design reviews and mentoring junior engineers

I'm looking for someone with strong practical engineering ability who can operate autonomously, make sound design decisions and act as a technical point of reference for the wider team.

This would suit an established Senior, Lead or Principal Mechanical Design Engineer who enjoys remaining hands‑on while taking greater ownership of engineering decisions and helping develop other engineers.
