SENIOR / PRINCIPAL MECHANICAL ENGINEER Manchester / Liverpool | Hybrid | Infrastructure & Engineering

Mechanical engineering. Big projects. Proper responsibility.

A leading UK infrastructure engineering and advisory business is expanding its Manchester / Liverpool team and is looking for a Senior / Principal Mechanical Engineer to play a key role in the delivery of major engineering programmes.

This isn't a role where you'll spend your days simply checking drawings and waiting for the next project to land.

You'll be expected to think, lead, challenge and engineer — working with clients and multidisciplinary teams to deliver solutions that work in the real world.

Your role
  • Lead mechanical engineering and design across complex projects
  • Develop designs from feasibility and concept through to detailed design and construction
  • Produce and review calculations, specifications, reports and technical documentation
  • Take technical ownership of mechanical packages
  • Coordinate designs with electrical, civil, structural and wider engineering disciplines
  • Work closely with clients, contractors, manufacturers and suppliers
  • Attend design reviews, site meetings and technical workshops
  • Provide technical leadership and mentoring to engineers and technicians
  • Support project planning, bids, proposals and business development
  • Help develop engineering standards, processes and best practice
What we're looking forYou'll ideally bring:
  • Significant mechanical engineering/design experience
  • Experience with in building services, infrastructure or multidisciplinary engineering
  • Strong knowledge of mechanical systems and UK design standards
  • Experience delivering technically complex projects
  • Degree/HNC/HND in Mechanical Engineering, Building Services or a related discipline
  • Strong communication and stakeholder management skills
  • Experience providing chemical guidance to less experienced engineers
  • CEng / IEng / working towards Chartership would be advantageous
  • Experience with relevant mechanical design and modelling software
Why consider it?

Because your next step shouldn't simply mean more emails, more meetings and a bigger spreadsheet.

At Senior / Principal level, you'll have the opportunity to:
  • Own technical decisions.
  • Lead projects.
  • Develop people.
  • Influence clients.
  • Shape the future of engineering.

You'll be joining a collaborative multidisciplinary environment working across some of the UK's most important infrastructure programmes, with genuine opportunities for professional development and progression.
