Propulsion Fluids Analyst Confidential search | Launch vehicle developer | Toronto, Ontario | Relocation and visa support provided
The Company A venture-backed launch vehicle developer building a new medium-lift orbital rocket, with a light-lift pathfinder vehicle establishing the manufacturing and test foundation ahead of it. The engineering team is made up of people who have built and flown orbital hardware at established US and European launch companies, and the programme carries both institutional government backing and commercial investment.
The engineering philosophy is deliberately unglamorous. A single engine that scales through clustering rather than redesign, proven technology over novel architecture, and a test-early culture that catches problems on the bench rather than at the pad.
THE ROLE A fluids analyst who is as comfortable with first order hand calculations as with running CFD or writing their own analysis code. You would work across design, analysis, development, operation and reuse scenarios in a fast-moving development environment.
This is a hands-on individual contributor seat for someone who wants to be close to the detail, make consequential design decisions, and establish the propulsion and stage fluids systems of an orbital launch vehicle programme from the ground up.
What You'll Do Analyze fluid transients, water hammer, priming, two-phase flow, cavitation, flow-induced loads, and feed system coupling across engine and stage fluid systems.
Perform thermal-fluid analysis of cryogenic propellants including chilldown, boiloff, and thermal conditioning.
Run trade studies on system architecture and operating points to inform design decisions.




Develop and validate pressurization system models (autogenous, helium, or self-pressurizing) to size pressurant requirements and predict ullage behaviour.
Build, run, and maintain system-level models in tools such as EcosimPro, ESPSS, Flownex, Fluent, CFX, or in-house Python and MATLAB codes.
Support cold flow, hot fire, stage test, and flight campaigns with pre-test predictions and post-test data reconciliation.
Support anomaly investigations and root-cause analysis for fluid-related issues.
Qualifications Required 7+ years of experience in fluid analysis, experience with cryogenic fluids, or both.
Inclination toward a fast-paced, resource-constrained environment with rapid hardware development, using iterative design-build-test cycles that are central to the engineering culture.
Preferred Sub, trans, super and hypersonic aerodynamics of the vehicle during ascent and re-entry.
Thermal, structural, turbomachinery fluid, or combustion analysis proficiency including liquid injection modelling.
Conjugate heat transfer analysis using Fluent or similar CFD tools on rocket engine components.
Experience with liquid bipropellant rocket engines and methane systems.
Exposure to complex fluid systems and an understanding of the behaviour of the mechanisms within them.
Functional proficiency in Visio, CAD, and Python.
PACKAGE Competitive base salary, substantial equity, and a one time signing bonus.
Six weeks of paid vacation per year plus statutory holidays.
Relocation expenses reimbursed, and visa support for you and your family, funded and managed by the company.
Comprehensive Canadian health, dental and disability coverage.
