Imagine joining a launch company at the point where the drawings are about to become concrete, steel, pipework and ultimately a place where rocket engines will fire.
This is not an established aerospace business maintaining infrastructure that already exists. The company is building Canada’s first medium-lift launch vehicle and much of the infrastructure needed to test, develop and launch it still needs to be created.
The team behind it includes veterans of some of the world’s most successful launch, aerospace and engineering organisations, bringing more than a century of combined launch and space systems experience to the programme.
The engineering philosophy is deliberately pragmatic.
A single 725 kN engine will scale from light- to medium-lift through engine clustering. Proven technologies are favoured over unnecessary complexity. Hardware will be tested early and often, finding problems on the test stand rather than discovering them at the launch pad.
And this isn’t a company waiting for funding before it can move.
More than $20M was secured within its first four months, including the largest all-Canadian seed round in the sector and an $8.3M Department of National Defence grant.
Now the infrastructure has to catch up with the ambition.
The Opportunity
We’re looking for an Infrastructure Engineering Program Manager who can help turn that ambition into something physical.
Test facilities. Launch infrastructure. Utilities. Equipment. Control systems. Concrete. Conduit.
You’ll take ownership of the technical baseline and integrated execution of the company’s test and launch infrastructure, from detailed design through construction and commissioning.
At many organisations, infrastructure sits quietly in the background.
Here, it is on the critical path.
The engineering decisions you make today will determine what gets built tomorrow and ultimately whether engines can be tested and vehicles can be launched.
You’ll act as the engineering authority for the programme, sitting at the intersection of engineering, procurement, construction and facilities.
You won’t necessarily design every system yourself. Instead, you’ll make sure the entire programme works as one integrated system.
You’ll manage third-party engineering firms across multiple disciplines, own requirements and the integrated schedule, establish the technical baseline and make the engineering decisions that construction and procurement execute against.
The environment is fast-paced, highly autonomous and deliberately lean.
What You’ll Own
You’ll translate programme requirements into engineering scopes, specifications and acceptance criteria, while establishing the change-control processes that keep engineering, procurement and construction working from the same technical baseline.
Third-party engineering firms will look to you as their primary technical interface. You’ll manage their scopes and deliverables, integrate work across disciplines and hold partners accountable for schedule, quality and technical performance.
You’ll own the integrated programme schedule and budget baseline across design, procurement and construction identifying the critical path and making sure long-lead decisions happen before they become programme delays.
When major equipment and systems need to be purchased, you’ll develop the technical specifications and work alongside Supply Chain to evaluate potential vendors.
As designs move towards reality, you’ll run design and constructability reviews alongside Construction and Facilities, resolving RFIs and engineering changes as issues emerge in the field.
And when the infrastructure is finally built, your responsibility doesn’t stop.
You’ll own the technical side of commissioning, defining commissioning plans, acceptance criteria and functional testing before signing off the systems for handover into operational use.
Ultimately, you’ll be the person keeping engineering, procurement, construction and facilities aligned around one technical plan.
The Team Around You
You won’t be doing this alone.
The infrastructure group is intentionally small, with clear ownership across four areas.
Engineering owns the technical baseline.
Supply Chain sources the equipment and manages commercial commitments.
Construction turns the designs into physical infrastructure.
Facilities takes ownership once those systems become operational.
The boundaries are clear, but in a company moving this quickly, collaboration matters more than job titles.
What We’re Looking For
You’ll likely have at least five years’ experience delivering infrastructure, facilities or complex industrial projects within environments such as aerospace, energy, advanced manufacturing or heavy industry.
You’ll have a strong engineering foundation and be comfortable reviewing drawings, specifications and multidisciplinary design packages rather than simply managing a programme from a spreadsheet.
Experience managing external engineering firms is important, as is the ability to hold suppliers and partners accountable for scope, schedule and quality.
You’ll understand integrated schedules and budgets, procurement workflows and equipment commissioning.
Most importantly, you’ll be comfortable operating somewhere where not every process already exists.
In some cases, you’ll be expected to build the process yourself.
Experience with test stands, propulsion infrastructure or hazardous fluid systems would be particularly valuable, as would exposure to instrumentation, DAQ or control architecture.
P.Eng status or eligibility in Ontario would also be advantageous, alongside knowledge of relevant Ontario building and fire codes and Canadian standards.
Why Join?
There aren’t many opportunities where an infrastructure engineer can point to a facility several years from now and say:
“I helped build that from the ground up.”
There are even fewer where the facility you’ve helped create exists to test rocket engines and support a national orbital launch capability.
The company already has the funding, engineering pedigree and launch ambition.

Principal RF/Microwave Engineer — Spaceborne Radar Payloads
About the opportunity
An early-stage space company is building advanced electronically-steerable radar payloads for Low Earth Orbit, and needs a principal-level RF/microwave engineer to own one of the highest-leverage parts of the architecture: the flight-ready, phase-coherent RF hardware that determines the payload's sensitivity, power, waveform fidelity, and overall mission performance.
This is a deeply hands-on principal role, not a systems-only or simulation-only seat. You'll own RF hardware end-to-end, from architecture and budgets through circuit and PCB design, simulation, lab characterisation, integration, qualification, calibration, and production readiness.
The mission context
The company's radar technology is based on mature phased-array heritage already in full-rate production for terrestrial and airborne applications, now being transitioned to flight-ready space hardware. The RF payload is central to that, and this role directly influences system sensitivity, RF power, efficiency, coherence, and mission performance. You'd be shaping next-generation spaceborne ISR, SAR, and MTI capabilities.
The two profiles
The team is growing, and there's appetite for more than one senior RF engineer. The work splits across two chains:
A transmit focus, centred on high-power amplification (GaN SSPA and drain-switching approaches), peak RF power, PAE, AM/PM fidelity, bandwidth, and the thermal and mechanical complexity that comes with high-power transmit. This is the rarer, more senior profile and the current priority.
A receive focus, centred on sensitivity, dynamic range, channel matching, gain and noise budgets, and calibration stability.
Strong candidates often bring depth in one and working knowledge of the other. If your centre of gravity is high-power transmit, we especially want to hear from you.
What you'll own
Own the RF architecture and performance budgets. Design and verify RF transmit and/or receive chains spanning digital interfaces, RF signal conditioning, amplification, filtering, and calibration. Retire RF, thermal, power, EMI/EMC, and integration risks. Collaborate across antenna, digital, power, and spacecraft disciplines. Transition qualified hardware into repeatable production.
A typical week
Roughly 60% design, simulation, and lab work, 20% integration and support, and 20% in meetings. This is a bench-heavy role by design.
What you'll bring
Expert RF/microwave design experience across transmit and/or receive chains: RF budgets, gain and noise analysis, linearity, dynamic range, phase noise, coherence, high-power amplification, filtering, matching networks, microwave PCB design, RF simulation, lab characterisation, and calibration. Experience developing space-qualified hardware, and ideally exposure to phased arrays, radar payloads, or aerospace RF systems.
The thing that matters most: you've personally architected and delivered complex RF/microwave hardware from requirements through bring-up, characterisation, integration, and qualification, and owned it end-to-end. Engineers who've played across disciplines, tried things, hit problems, and iterated their way through are exactly the profile. Deep but narrow experience, owning one fixed slice of a chain for years without that broader ownership, is not what this role needs.
You're hands-on, rigorous, curious, and high-ownership, with strong first-principles judgement, disciplined lab habits, comfort with ambiguity, and the ability to mentor while remaining a strong individual contributor.
Practical requirements
This is an on-site role in the Seattle area. Given the mission set, US citizenship and the ability to meet security clearance requirements are required.
The honest preview
The upside is exceptional ownership of advanced radar hardware, genuinely hard RF problems, rapid design-test cycles, and direct impact on flight hardware and mission performance. The hard parts are aggressive schedules, evolving requirements, tightly coupled multidisciplinary interfaces, space-qualification constraints, and the expectation to solve problems hands-on at the bench. It suits a builder who wants deep ownership, not a specialist looking to run one narrow slice.
