This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Senior Orbit Dynamics & Mission Analysis Engineer based in Canada. Take on a senior technical role advancing complex space missions through sophisticated astrodynamics, orbital mechanics, and mission design. You will lead high-level engineering analyses, optimize spacecraft trajectories, and develop simulation models that support critical mission decisions. Using advanced tools such as STK, Python, and MATLAB, you will transform complex orbital dynamics challenges into practical, data-driven engineering solutions. You will conduct multidisciplinary trade studies, evaluate mission architectures, and provide technical recommendations to engineering stakeholders. This opportunity combines deep theoretical expertise with hands-on computational engineering in a technically demanding aerospace environment. The role is remote-oriented but requires at least 50% on-site work in Montreal, Quebec, with candidates willing to relocate permanently strongly preferred.
