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 strong 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, team-oriented 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%
