Principal Mechanical Engineer - Low Carbon
Location: Remote with occasional visits to the office for project meetings
Team: Energy Transition
Shape the future of low‑carbon energy!
We're looking for a Principal Mechanical Engineer to join our client's growing Energy Transition Team and play a leading role in delivering the next generation of low‑ and zero‑carbon energy projects. If you thrive on solving complex engineering challenges and want to influence the UK's transition to cleaner energy, this is a role where your impact will be felt for decades.
About the Role
As a senior member of a multidisciplinary engineering group, you will lead the development of mechanical designs across a diverse portfolio of energy projects - from early‑stage concept work through to construction, operation and eventual decommissioning.
The work spans:
- Conventional power generation
- Energy‑from‑waste facilities
- Industrial energy systems
- Carbon capture, utilisation and storage (CCUS)
- Future fuels and first‑of‑a‑kind low‑carbon technologies
You'll collaborate with private developers, utilities, government bodies, lenders, EPC contractors and OEMs to deliver safe, efficient and innovative engineering solutions.
What You'll Be Doing
- Developing cost‑effective, practical mechanical engineering solutions to complex problems
- Working across all project stages: Feasibility, Concept, FEED, Value Engineering and Detailed Design
- Producing mechanical deliverables including calculations, equipment specifications and datasheets for turbines, compressors, pumps, pressure vessels and heat exchangers
- Collaborating with process engineers on PFDs and P&IDs
- Supporting plant layout development and 3D model reviews
- Working with equipment vendors and evaluating technical proposals
- Providing engineering advice on plant integrity issues for operational assets
- Contributing to mechanical discipline bids and wider multi‑disciplinary proposals
What We're Looking For
- Degree in Mechanical Engineering or a related discipline
- Chartered Engineer (or working towards IEng/CEng) with a relevant professional institute
- Post‑graduate experience in Power Generation or Oil & Gas
- Strong knowledge of industry codes and standards for plant equipment and piping design
- Experience in pressure vessel and piping design, including stress analysis
- Familiarity with plant 3D modelling, working alongside designers and pipe stress engineers
- Proficiency in MS Excel for schedules/datasheets and MathCAD for engineering calculations
- Experience with operational thermal plant, troubleshooting and integrity assessments
- Knowledge of gas turbine systems; reciprocating engine experience is an advantage
- Experience with OEMs, EPC contractors or similar organisations; O&M experience highly desirable
You'll be part of a team at the forefront of the energy transition, working on projects that push the boundaries of engineering innovation. We offer flexible working locations, opportunities for professional growth, and the chance to influence major low‑carbon infrastructure across the UK and beyond.
