Location: London & Toronto, Canada
Compensation: Competitive base salary + package
Build the facility where a new rocket engine will come to life.
We are partnering with an ambitious heavily backed space launch company developing the next generation of launch vehicle technology in Canada.
Backed by significant funding and led by engineers from some of the world’s most successful aerospace and launch organisations, the company is now building the infrastructure required to develop, test and ultimately launch its vehicle.
This isn’t a role where you’ll spend your day watching hardware from behind a desk. You’ll be the person putting your hands on it.
At the heart of the programme is a 725 kN liquid rocket engine — and they are now building the team that will assemble, install, test and ultimately help fire it.
They’re looking for hands-on Mechanical Test Technicians to join their propulsion test operation in Canada.
If you’ve worked around high-pressure systems, cryogenics, fluid systems, turbomachinery, aerospace hardware or complex mechanical equipment, this is an prospect to take that experience into rocket propulsion.
The Mission Your job is simple to describe, but difficult to execute:
Make sure the hardware is ready to fire.
You’ll work alongside propulsion and test engineers preparing rocket engines and test articles for hot-fire campaigns.
One day you could be mounting an engine onto a test stand. The next you’ll be installing instrumentation, connecting high-pressure fluid systems,



torquing critical fittings or performing leak and pressure checks before a firing.
When a test is complete, you’ll help tear the hardware down, inspect it, identify what survived, what didn’t, and prepare everything for the next iteration.
You’ll be working directly with hardware operating under extreme pressures, temperatures and loads, where attention to detail genuinely matters.
What You’ll Be Doing Assemble and disassemble rocket engines, aerospace components and mechanical subassemblies
Mount engines and test articles onto propulsion test stands
Install sensors, transducers, thermocouples and instrumentation
Build and connect fluid and gas systems
Perform pressure testing and leak checks
Torque fittings and mechanical interfaces to precise specifications
Inspect hardware and verify configurations before testing
Support rocket engine hot-fire campaigns
Calibrate and check valves, actuators and regulators
Safely tear down hardware following tests
Inspect components for damage, wear and anomalies
Refurbish hardware ready for the next test campaign
Help build, modify and maintain the wider test facility and test stands
Work directly with test engineers,



quality teams and design engineers to solve problems quickly
What We’re Looking For You don’t necessarily need to have worked on rockets before.
We’re interested in people from aerospace, aviation, oil & gas, defence, automotive, industrial testing, manufacturing or other demanding mechanical environments where safety and precision matter.
You’ll Ideally Bring 2+ years of hands-on mechanical assembly, maintenance or technician experience
Experience working with mechanical or fluid systems
Ability to read engineering drawings, schematics and technical instructions
Confidence using hand tools, power tools and precision measuring equipment
Experience with torque wrenches, calipers and micrometers
Knowledge of plumbing, tubing and fittings such as AN/MS/JIC
Understanding of mechanical assembly, fasteners and safety wiring
Strong attention to detail and a safety-first mindset
Why Join? This is an opportunity to join a rocket programme while the test capability is still being built — not after everything has already been established.
You’ll help build the facility, install the hardware, support the test campaigns and watch systems you’ve physically worked on come alive during hot-fire testing.
Getting a new launch vehicle to orbit. If you’re a hands-on mechanical technician who has spent your career around serious hardware and you’ve ever wondered what it would be like to apply those skills to rocket engines, I’d love to hear from you.
