About Canada Rocket Company

Canada Rocket Company is developing Canada's first medium-lift launch vehicle.

We are a team of veterans from SpaceX, Blue Origin, Rocket Lab, ArianeGroup, Pangea Propulsion, Tesla, MDA, and more, bringing over a century of combined launch and space systems experience back to Canada.

Our mission is to provide reliable, independent access to space for Canada and its allies in a rapidly expanding global market.

Our approach is defined by pragmatic engineering:

• We utilize a single 725 kN engine that scales from light- to medium-lift via engine clustering.
• We lean on simple, proven technologies to reach orbit faster, avoiding the pitfalls of complex or novel designs.
• We test early and often, catching problems on the bench instead of at the pad.

Backed by over $20M in funding secured within our first four months, including the largest all-Canadian seed round in the sector and an $8.3M Department of National Defence grant, we are moving with the speed and institutional backing required to meet Canada’s orbital launch needs.

About the role

Canada Rocket Company is building a sovereign launch capability for Canada. As a mechanical technician at the Canada Rocket Company’s rocket test facility you would serve as the hands-on backbone of propulsion testing operations. This role is responsible for assembling, installing, maintaining, and troubleshooting facility systems, aerospace components, turbomachinery, and a 725 kN rocket engine. Day to day, this involves mounting test articles and engines onto test stands, installing sensors and instrumentation, torquing fittings to precise specifications, and performing leak checks to ensure systems can safely handle cryogenic fuel and oxidizer under extreme pressures and temperatures. The technician works closely with test engineers to prepare for hot-fire campaigns, conducting pre-test inspections, supporting valve and actuator calibrations, and verifying that every mechanical interface meets stringent safety and quality standards. Because rocket testing carries inherent hazards, attention to detail and strict adherence to procedures are essential—a single overlooked connection or improperly torqued bolt can jeopardize both expensive hardware and personnel safety. Beyond test execution, the role often includes post-test teardown, hardware inspection for damage or wear, refurbishment, and documentation, all of which contribute to the iterative process of developing and qualifying reliable propulsion systems.

What you'll do

• Assemble and disassemble rocket engines, components, and subassemblies according to engineering drawings, work instructions, and specifications
• Mount test articles, engines, and hardware onto test stands and fixtures.
• Install and connect instrumentation, sensors, transducers, and thermocouples
• Perform leak checks and pressure tests on fluid and gas systems
• Conduct pre-test inspections and verify hardware configuration against documentation
• Support hot-fire test operations, including setup, console support, and safing procedures
• Perform post-test teardown, inspection, and hardware refurbishment
• Identify, document, and report hardware damage, wear, anomalies, and discrepancies
• Calibrate and check valves, actuators, regulators, and other mechanical components
• Complete documentation, travelers, and quality records for traceability
• Collaborate with test engineers, quality inspectors, and design teams to resolve technical issues
• Support facility and test stand build, modifications, maintenance, and upgrades

Qualifications

• Required:
• Technical/trade certification or associate degree in a relevant field (mechanical technology, aerospace, welding, machining, etc.)
• 2+ years of hands-on mechanical assembly, maintenance, or technician experience (often in aerospace, oil and gas, military, automotive, manufacturing, or industrial settings)
• Ability to read and interpret engineering drawings, blueprints, schematics, and technical work instructions
• Experience using hand tools, power tools, and precision measuring instruments (calipers, micrometers, torque wrenches)
• Familiarity with fluid systems, plumbing, tube bending, and AN/MS/JIC fittings
• Working knowledge of mechanical assembly techniques, including torquing, safety wiring, and fastener installation
• Ability to follow detailed written procedures and maintain accurate documentation
• Strong attention to detail and commitment to safety and quality standards
• Ability to work in a team environment and communicate effectively
• Physical ability to lift moderate to heavy loads, stand for extended periods, climb, bend, and work in confined spaces or at heights
• Willingness to work overtime, weekends, shift work, or non-standard hours to support test schedules

Preferred:

• Direct experience with rocket propulsion, test stands, or test facility operations
• Experience working with high-pressure systems, cryogenic fluids, propellants, or hazardous materials
• Experience installing instrumentation, sensors, transducers, and thermocouples
• Knowledge of cleanliness requirements for oxygen systems and precision cleaning practices
• Experience operating cranes, hoists, forklifts, or other material-handling equipment (with relevant certifications)
• Welding, brazing, or soldering experience and certifications
• Familiarity with quality systems such as AS9100 and FOD prevention practices
• Experience in a regulated environment (aerospace, defense, NASA, or similar)
• Forklift, crane/rigging, or hazmat handling certifications
• Proficiency with basic computer applications and data entry for documentation
• Active or eligible security clearance (for certain government-related programs)
