We are seeking a  Structural Designer  to lead the structural development and verification of spacecraft subsystems.  

This role combines structural analysis, mechanical design influence, hardware development, testing, and cross-functional collaboration to ensure spacecraft systems survive launch, deployment, and operational environments while meeting demanding performance, mass, and reliability requirements. The successful candidate will own structural performance from concept through qualification, working closely with systems, RF, electrical, software, mechanical, manufacturing, AIT, and mission operations teams to develop robust and scalable solutions.  

The ideal candidate thrives in environments where performance, mass, reliability, manufacturability, schedule, and cost must all be balanced to achieve mission success. They are equally comfortable developing analytical models, interpreting test data, influencing design decisions, and solving complex multidisciplinary challenges.  

This role is an opportunity to directly influence the next generation of Kepler spacecraft while helping establish the engineering practices, technical rigor, and structural engineering capability that will enable Kepler to become a world leader in spacecraft development and space infrastructure.  

Key Responsibilities:

Structural Development & Ownership  

Lead the structural development and verification of spacecraft subsystems from concept through flight qualification and successful transition into production

Own subsystem-level structural development activities including structural modeling, design assessment, verification, testing, qualification, and risk reduction

Assess spacecraft hardware performance under static, dynamic, vibration, shock, deployment, and operational loading environments

Drive structural trade studies and influence design decisions using first-principles engineering, simulation, testing, and sound engineering judgment  

Identify structural risks early and recommend design improvements that enhance performance, reliability, manufacturability, and qualification success

Demonstrate compliance with structural requirements through analysis, testing, and documented margins of safety

Analysis, Verification & Risk Reduction  

Develop and maintain structural models used to predict spacecraft and subsystem performance

Define structural verification strategies and success criteria aligned with mission requirements  

Plan and execute qualification activities including vibration, static load, modal, shock, and other environmental test campaigns

Correlate simulation results with physical testing to continuously improve model fidelity and engineering confidence

Support hardware development teams by translating analysis findings into practical design recommendations

Lead root-cause investigations and drive complex technical issues through to resolution

Cross-Functional Collaboration  

Work closely with systems, RF, electrical, software, mechanical, manufacturing, supply chain, AIT, and mission operations teams to develop integrated spacecraft solutions

Facilitate technical discussions regarding structural performance, design trades, risks, and recommendations

Coordinate structural activities across stakeholders to ensure successful integration, verification, and delivery

Engineering Excellence  

Contribute to the continuous improvement of structural engineering methods, analysis approaches, verification practices, and development workflows  

Act as a peer reviewer, mentor junior engineers, and provide technical leadership within project teams

Promote a culture of technical rigor, accountability, collaboration, and continuous learning

Required Skills & Qualifications:

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Mechatronics Engineering, or equivalent

4+ years of experience developing and verifying structural solutions for complex mechanical, aerospace, or spacecraft systems

Strong understanding of structural mechanics, dynamics, vibration, shock, fatigue, failure modes, and margins of safety

Experience developing and correlating structural models using simulation and physical testing

Experience assessing designs under static, dynamic, vibration, shock, deployment, and operational loading environments

Experience defining structural verification approaches and qualification strategies

Demonstrated willingness and ability to leverage AI-assisted engineering and development tools to improve productivity, design quality, and innovation while adapting to evolving technologies and best practices

Experience with NASTRAN-based analysis environments such as Simcenter 3D, NX NASTRAN, FEMAP, MSC NASTRAN, or equivalent

Experience with CAD platforms such as Onshape, Creo, SolidWorks, NX, or equivalent

Strong communication and documentation skills working within multidisciplinary engineering teams

Comfortable operating in a hands-on development environment involving prototyping, testing, troubleshooting, and hardware development

Bonus Points:

Experience developing spacecraft, satellite, aerospace, or other mission-critical hardware

Experience assessing and managing structural interfaces between spacecraft platforms and customer payloads

Experience planning and executing environmental qualification testing and correlating results to analytical models  

Familiarity with ESA ECSS, NASA, or equivalent aerospace structural engineering standards  

Experience supporting hardware transition from development into production

Experience working with lightweight structures, deployable systems, mechanisms, or precision mechanical assemblies

Eligibility for Professional Engineer (P.Eng.) licensure in a Canadian jurisdiction

Salary Range: $100,622 - 150,622 CAD
