About Canadian Strategic Missions Corp. (CSMC)
Canadian Strategic Missions Corporation is building the capabilities that will shape Canada's future in space, defence, and energy. We focus on developing dual use systems that address critical challenges here on Earth while enabling sustained human activity beyond it.

Ina short time, CSMC hasestablishedreal momentum. WE have secured significant government investment to advance next generation micro nuclear reactors in partnership with leading institutions, alongside expanding a portfolio of technologies designed for remote environments, national defence, and future space missions. These efforts reflect a broader ambition to deliver reliable power and critical infrastructure where it matters most.
Our work is grounded in close collaboration with government and guided by a clear sense of purpose: to build sovereign capability at a time when it has never been more important. We care deeply about execution, long term impact and earning the trust required to deliver systems that will service Canada and its allies for decades.

CSMC is a company for builders. We are a group of people drawn to hard problems, meaningfulimpactand the opportunity to shape systems that matterata national and global scale. We are building a team that thrives in ambiguity, values execution, and is motivated by mission and impact.

About the Role

CSMC is seeking a Space Systems Engineer to lead the design, integration, and delivery of space based systems and mission architectures. This role is focused specifically on space systems development, including spacecraft, payloads, ground segment integration, and mission design, rather than traditional aerospace or aviation platforms.

You will work at the intersection of systems engineering, orbital mechanics, and mission execution, partnering with interdisciplinary teams to design and deliver systems that operate in space environments and other mission critical conditions.

This role is best suited for engineers who have hands on experience designing or integrating space systems and who are motivated to apply that expertise to programs tied to national security, space infrastructure, and advanced technology development.

Responsibilities

• Lead systems engineering activities for space-based systems across the full lifecycle (concept mission definition design integration validation deployment)
  
• Define and manage mission-level and system-level requirements, ensuring traceability from orbital/mission objectives to subsystem design
  
• Design and evaluate space system architectures, including: spacecraft / satellites, payload integration, ground segment and communications interfaces
• Conduct trade studies and mission analyses, including: orbit selection, mass/power budgets, payload performance trade-offs
• Coordinate integration across spacecraft subsystems:avionics (space-rated), ADCS / GNC, power / thermal communications
• Support space mission design and planning, including system-of-systems considerations (space + ground + data layers)
• Lead or support verification and validation planning for space systems, including environmental and operational constraints
• Collaborate with internal teams and external partners (including government, space agencies, and contractors) on program execution
• Support development of technical proposals and mission concepts for space, defence, and national security applications
• Identify and manage risks specific to space systems, including reliability, redundancy, and mission failure modes

Qualifications

Must Have

• Bachelor's degree in Aerospace, Mechanical, Electrical, or Systems Engineering (or similar)
• An absolute minimum of 2-5+ years of experience working on space systems (NOT aircraft / traditional aerospace)
• Demonstrated experience with one or more:
  • spacecraft or satellite design/integration
  • mission systems engineering for space programs
  • payload integration or space hardware development
• Experience translating mission requirements into system architecture for space-based applications
• Familiarity with space-specific engineering constraints, such as:vacuum / thermal / radiation environments
  • mass, power, and bandwidth limitations
• Experience working on complex, multi-disciplinary space systems
• Strong systems thinking, analytical capability, and ability to communicate technical concepts clearly

Preferred

Experience with:

• Satellite systems (LEO/MEO/GEO)
• Smallsat / CubeSat platforms
• Space payloads (sensing, communications, ISR, etc.)
• Model-Based Systems Engineering (MBSE) (Cameo, SysML)
  
• Space mission analysis tools (e.g., STK, GMAT)
  

Background in:

• GNC / ADCS
  
• orbital mechanics / astrodynamics
  
• RF communications / space links
  
• spacecraft thermal or power systems

Experience working with:

• Space agencies (CSA, NASA, ESA)
  
• Defence or national security space programs

Familiarity with:

• Space qualification / flight heritage
• Reliability and redundancy design for space systems

Please note that candidates whose experience is primarily in aircraft systems, avionics, automotive, or industrial systems without direct space system experience will not be considered.
