Job description

Senior Mechanical Engineer GBP70,000 - GBP80,000 DOE Central London

THE HOOK

Your last three jobs blurred together. Same desk, same problems, incremental pay rises that barely kept pace with inflation. But what if the next move wasn't a lateral shift, what if it was into a business where you could actually see your impact, where technical expertise still counts, and where the person before you didn't leave because the culture was broken? Our client is hiring because they're growing, not because they're in trouble.

WHAT THIS JOB IS

You'd be a Senior Mechanical Engineer supporting the Technical Services team across Central London. The business is a principal contractor built on in-house expertise, they don't outsource their backbone. You'd work with a stable, long-standing client base and a pipeline full enough that you'll never run out of problems to solve. The company started over 40 years ago doing small moves and changes; they've grown into something substantial by genuinely understanding what clients need and delivering it consistently. That's not hype. That's decades of proof.

SO WHAT? WHICH MEANS?

You'd be joining a business where Safety, Quality, Integrity and People aren't slogans on a wall, they've survived decades of growth because they're how decisions get made. Which means your technical recommendations won't get buried in cost-cutting politics; they'll be heard. The progression prospects are real because there's no dead-end here. A business growing organically needs people who can grow with it, into team leadership, into strategic technical input, into genuine seniority. Which means if you've been waiting for a place where competence translates into opportunity, this is it.

You'd have stable work. A stable operation with established clients and a full pipeline doesn't send people home on Fridays because the work dried up. Which means you can plan your career, not just your next month. The business is profitable, reputable, and built to last. Which means you're betting on something solid.

THE REAL THING

You'll be busy. The pipeline is strong, so you'll move between different projects. If you need downtime between commissions, this isn't the job. If you want constant momentum and variety, you'll find it here.

THE BUSINESS

Our client is a principal contractor serving major corporate and institutional clients across London. They employ in-house tradespeople, engineers, and technical teams, they've bet their reputation on quality and direct control, not subcontracting shortcuts.

WHAT WE NEED

Minimum 5 years' senior mechanical engineering experience. Chartered or on track to chartered status. Current knowledge of Building Regulations and relevant mechanical systems design.
