Fluids Engineer

NordSpace Corp.; Markham; Hybrid; CAD 60,000 - 80,000; Full time

Job summary

NordSpace Corp. in Markham, ON seeks a Fluids Engineer to design, analyze, and test propellant fluid systems, contributing from concept through hardware qualification.

You'll work with cross-functional teams to model steady-state and transient behavior, run CFD analyses, select components, and generate P&IDs, ensuring safe, reliable propulsion hardware for rocket systems. This is an early-career opportunity in a fast-growing aerospace startup with hands-on testing on the shop floor.

Qualifications

• Bachelor's degree in Mechanical, Aerospace, Chemical Engineering or related field; practical experience accepted.
• Solid grounding in fluid mechanics and thermodynamics, including compressible and two-phase flow.
• Experience with fluid system modeling or simulation tools.
• Working knowledge of CFD for component-level flow analysis.
• Familiarity with propellant properties (LOX, RP-1, nitrogen).
• Comfortable with cryogenic fluid systems and safety practices.
• Strong analytical and problem-solving skills; able to work from first principles.
• Experience reading and generating P&IDs, schematics, and drawings.

Responsibilities

• Design and analyze propellant feed systems, including tanks, pressurization, valves, regulators, and manifolds.
• Perform fluid dynamics analysis (incompressible, compressible, two-phase, cavitation, water hammer, transient flow) using analytical methods and CFD.
• Size and select components; generate flow schematics (P&IDs) for engine and ground systems.
• Develop and maintain fluid system models (EcosimPro/ESPSS, Simulink, Flownex, Python/MATLAB) for steady-state and transient behavior.
• Support trades for propellant and pressurant selection and system-level mass/performance.
• Collaborate with Structures, Propulsion and Avionics to ensure integration with tanks and manifolds.
• Define instrumentation and test requirements for hot-fire and cold-flow testing; assist planning and data analysis.
• Root-cause analysis of testing anomalies and propose fixes.
• Generate technical documentation: analyses, reviews, requirements and verification plans.
• Support hardware fabrication, assembly, and leak/flow testing of components.

Job description

Engineering - Launch Systems Full Time Markham, ON $60,000 - $80,000 CAD per year

NordSpace(https://nordspace.com) is a Canadian startup with the mission to advance life on Earth, from space.NordSpaceis committed to extremely rapid innovation and development of the most ambitious aerospace projects with the most ambitious team. With divisions spanning everything fromspace robotics to satellites torockets,NordSpaceis driven to bring space closer to Earth and inspire generations of space explorers.

Role purpose:

We are looking for a Fluids Engineer to join our Structures team and help design, analyze, and test the fluid systems that manage our propellant feed systems. You'll work across the full lifecycle of propellant tanks and feed-system development from trade studies and first-principles modeling through hardware testing and flight qualification. This is both an analytical and hands-on role for someone who wants to see their analysis translate directly into hardware on the test stand and, ultimately, on the launch pad.

At NordSpace, you'll play a meaningful role in developing technologies that make a difference in the rocket industry. We believe in investing in early-career talent and providing opportunities to learn, innovate, and grow alongside industry experts. If you're excited about solving complex challenges, we'd love to hear from you

Core responsibilities

• Design and analyze propellant feed systems, including propellant tanks, pressurization systems, valves, regulators, ducting, and manifolds for liquid rocket engines and vehicle-level fluid systems
• Perform fluid dynamics analysis (incompressible and compressible flow, single- and two-phase flow, cavitation, water hammer, and transient flow phenomena) using both analytical methods and CFD tools
• Size and select components such as valves, orifices, filters, regulators, and relief devices; generate flow schematics (P&IDs) for engine and ground support systems
• Develop and maintain fluid system models (e.g., in EcosimPro/ESPSS, Simulink, Flownex, or custom Python/MATLAB tools) to predict steady-state and transient system behavior
• Support propellant and pressurant selection trades, tank pressurization schemes (autogenous, cold gas, etc.), and system-level mass/performance trades
• Work closely with Structures, Propulsion and Avionics engineers to ensure fluid systems integrate cleanly with propellant tanks, pressurization systems, and propellant manifolds
• Define instrumentation and test requirements for component- and system-level hot-fire and cold-flow testing; support test planning, execution, and post-test data analysis
• Root-cause anomalies observed in testing (e.g., cavitation, pogo, water hammer, chugging, flow instabilities) and propose design or operational fixes
• Generate and maintain technical documentation: analysis reports, design review packages, requirements, and verification/qualification plans
• Support hardware fabrication, assembly, and proof/leak/flow testing of fluid components

Qualifications

• Bachelor's degree in Mechanical, Aerospace, Chemical Engineering, or a related field (or equivalent practical experience)
• Solid grounding in fluid mechanics and thermodynamics, including compressible flow, two-phase flow, and transient (unsteady) flow analysis
• Experience with fluid system modeling or simulation tools
• Working knowledge of CFD (e.g., ANSYS Fluent, STAR-CCM+, OpenFOAM) for component-level flow analysis
• Familiarity with propellant and pressurant properties relevant to liquid rocket propulsion (e.g., LOX, RP-1, nitrogen)
• Comfortable working with cryogenic fluid systems and associated safety practices
• Strong analytical and problem-solving skills with the ability to work from first principles when tools or data are limited
• Experience reading and generating P&IDs, schematics, and engineering drawings
