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. If you're an experienced mechanical engineer and open to hearing about a new opportunity, drop me a message or send your CV across for a confidential conversation
