Senior Orbit Dynamics & Mission Analysis Engineer

About the role

We are looking for a Senior Orbit Dynamics & Mission Analysis Engineer to lead the development and execution of advanced orbit dynamics and mission analysis for a variety of space missions. The role involves designing satellite trajectories, optimizing constellations, and providing technical leadership to junior engineers.

Key responsibilities

• Lead the development and execution of advanced orbit dynamics and mission analysis tasks for various space missions.
• Architect, design, and optimize complex satellite trajectories, maneuvers (low‑thrust, impulsive), and constellation configurations using STK and custom tools.
• Develop, implement, and validate high‑fidelity simulation models and analysis software using Python, MATLAB, and/or C#.
• Perform specialized analyses such as coverage, communications link budgets, conjunction assessment, re‑entry predictions, orbit determination, and attitude dynamics interactions.
• Define mission requirements related to trajectory and orbital performance and contribute to system architecture trade‑offs.
• Develop novel analysis techniques and automate complex simulation workflows.
• Provide technical leadership and mentorship to junior engineers.
• Prepare and present detailed technical reports and recommendations to internal teams, management, and external stakeholders.

Required profile

• Master’s degree in Aerospace Engineering, Astronautical Engineering, Physics, Applied Mathematics or a related field (or Bachelor’s with significant experience).
• Minimum of seven years of professional experience in orbit dynamics, astrodynamics, trajectory optimization and space mission design.
• Expert‑level proficiency with Systems Tool Kit (STK) including advanced modules and automation/scripting.
• Advanced programming experience in Python and MATLAB (and preferably C#).
• Strong theoretical and practical knowledge of orbital mechanics, perturbation theory, estimation techniques and trajectory optimization methods.
• Proven ability to lead technical analyses, conduct complex trade studies and solve challenging astrodynamics problems independently.
• Excellent written and verbal communication skills in English; French is a plus.

Required skills

• STK (Astrogator, Optimizer, Coverage, Comm) and STK automation/scripting.
• Python programming.
• MATLAB programming.
• C# and C/C++ programming.
• Git version control.
• SPICE toolkit.
• GMAT, FreeFlyer, Orekit simulation environments.
• Orbit determination and trajectory optimization techniques.
