At Spaceium, we are building spacecraft systems designed to push the boundaries of what's possible in orbit. As a Mechanical Engineer, you will design and develop mechanical systems and structures for our spacecraft platforms. You will own the mechanical design lifecycle from concept through manufacturing and testing, ensuring our hardware is flight-ready and reliable.
RESPONSIBILITIES Design mechanical components, assemblies, and structures for spacecraft systems
Perform structural, thermal, and tolerance analysis on mechanical designs
Create detailed drawings and 3D models using CAD software
Work with manufacturing partners to produce prototypes and flight hardware
Develop and execute test plans for mechanical qualification and acceptance
Conduct trade studies on materials, fasteners, and joining methods
Collaborate with systems, electrical, and software engineers on integrated design
Support assembly, integration, and test activities
BASIC QUALIFICATIONS Bachelor's degree in Mechanical Engineering or a related field
Experience with 3D CAD tools (SolidWorks, NX, or similar)
Understanding of materials, manufacturing processes, and GD&T;
Experience with version control or configuration management
WHAT WE'RE LOOKING FOR We're building technology that hasn't been done before. Experience is helpful, but curiosity, drive, and the ability to learn quickly matter more.



If you're excited about spacecraft, enjoy solving hard engineering problems, and want to help build something new, we encourage you to apply — whether you're early in your career or more experienced.
PREFERRED SKILLS Creative problem solver with robust first-principles thinking, capable of assessing risk and making decisions with limited data.
Experience in a nimble, technical engineering role, with a scrappy, entrepreneurial approach to meeting tight time or budget constraints.
Experience with FEA tools (ANSYS, Nastran, or similar)
Familiarity with space-rated materials and thermal environments
Knowledge of mechanism design and actuator selection
Experience with cleanroom assembly and handling procedures
Understanding of vibration, shock, and launch load environments
Excellent verbal and written communication skills, collaborative team player, and detail-oriented with a focus on quality.
ADDITIONAL REQUIREMENTS Extended hours and weekend work may be required to support critical project and mission milestones.
This role requires a physical presence at the Ottawa facility.
COMPENSATION Salary: $75,000 – $110,000 CAD per year
Equity: 0.1% –0.5%
If you're excited about shaping the future of space systems, we’d love to hear from you.
