Aerospace Systems Engineer

CSMC is seeking a Senior Aerospace Systems Engineer to support the design, integration, and delivery of advanced aerospace and defence systems.

This role sits at the intersection of engineering, mission design, and program execution, and will contribute directly to the development of complex, multi-domain platforms across aerospace, energy, and national security applications.

You will work closely with cross-functional teams of engineers, scientists, and program leaders to define system architectures, manage technical trade-offs, and ensure that integrated systems meet performance, reliability, and mission requirements.

This role is ideal for a systems engineer who thrives in high-consequence environments and is motivated by building technologies with real-world impact.

• Lead systems engineering activities across the full lifecycle, including requirements definition, system architecture, integration, validation, and verification
• Define and manage system-level requirements, ensuring traceability from mission objectives to subsystem specifications
• Coordinate integration across hardware, software, and embedded systems, ensuring alignment and performance across subsystems
• Conduct trade studies and technical analyses to support design decisions and optimize system performance
• Collaborate with internal teams and external partners to align technical development with program objectives and timelines
• Support development of technical proposals, RFP responses, and program documentation for government, defence, and aerospace opportunities
• Participate in risk identification and mitigation planning across engineering and program delivery
• Contribute to system testing, validation, and field deployment activities
• Maintain awareness of evolving aerospace, defence, and dual-use technologies, informing system design and product strategy

• Bachelor’s degree in Aerospace Engineering, Systems Engineering, Electrical Engineering, Mechanical Engineering, or related field
• 5+ years of experience in systems engineering within aerospace, defence, or complex hardware environments
• Demonstrated experience with system integration, requirements management, and lifecycle engineering processes
• Experience working on multi-disciplinary systems involving hardware, software, and/or embedded components
• Familiarity with regulated or high-reliability environments (e.g., aerospace, defence, nuclear, or critical infrastructure)
• Strong analytical, problem-solving, and communication skills
• Ability to work effectively in cross-functional, fast-paced environments

• Experience with: Aerospace platforms (UAVs, avionics, spacecraft, or mission systems) Defense or government programs, including RFP processes and structured program delivery Systems engineering tools (e.g., DOORS, Cameo, MATLAB/Simulink)
• Aerospace platforms (UAVs, avionics, spacecraft, or mission systems)
• Defense or government programs, including RFP processes and structured program delivery
• Systems engineering tools (e.g., DOORS, Cameo, MATLAB/Simulink)
• Knowledge of: Model-Based Systems Engineering (MBSE) principles Safety, reliability, and certification frameworks
• Model-Based Systems Engineering (MBSE) principles
• Safety, reliability, and certification frameworks
• Experience in systems architecture, system-of-systems design, or mission engineering
• Advanced degree (M.Sc., M.Eng.) or equivalent experience
