Job Summary

We are seeking a skilled Astrodynamics Engineer to join our team, specializing in the design, analysis, and optimization of satellite orbits. The ideal

candidate will be responsible for conducting advanced orbital mechanics simulations,

optimizing orbital trajectories, and leveraging state-of-the-art tools for mission planning and

analysis.

Job Responsibilities

∙Design and analyse satellite orbits and model relevant manoeuvres for a variety of

missions, including LEO, MEO, GEO, and interplanetary trajectories.

∙Develop and optimize orbital transfer strategies, station-keeping manoeuvres, and

end-of-life de-orbit planning.

∙Perform high-fidelity simulations of satellite missions using self-programmed

algorithms and trajectory models required for FoV studies, illumination and energy

balance as dictated by the requirements of GNC, Power and Thermal subsystems.

∙Collaborate with systems engineering teams to integrate orbital designs into mission

architectures.

∙Conduct trade studies to evaluate mission scenarios, orbit selection, and propulsion

needs.

∙Generate detailed reports and visualizations of mission analyses to support decision-

making in the mission operations of the spacecraft.

∙Stay updated on emerging trends in astrodynamics, orbit optimization algorithms, and

mission design techniques.

Qualifications

Education :

∙ Master’s degree in Aerospace Engineering, Astrodynamics, Physics,

Mathematics or a related field. A Ph.D. in the relevant field is a plus.

Technical Skills :

∙Strong expertise in orbital mechanics, including advanced perturbation theory, multi-

body dynamics, and relative motion.

∙Proven experience in orbit optimization techniques, such as low-thrust trajectory

design, optimal control theory, delta-v minimization, and constellation management.

∙Proficiency in using simulation tools such as STK (Systems Tool Kit) , NASA's

GMAT (General Mission Analysis Tool) , Freeflyer, MATLAB , Python , or

equivalent.

∙Familiarity with numerical optimization libraries (e.g., SciPy, CPLEX, or Gurobi) and

astrodynamics-specific toolkits (e.g., Orekit or Poliastro) is highly desirable.

Experience :

∙2-8 years of hands-on experience in orbit simulation, mission analysis, optimization or

related fields.

∙Demonstrated ability to develop custom scripts and workflows for mission-specific

requirements.

∙Experience with spacecraft subsystems and their impact on orbit design (e.g.,

propulsion, power, thermal).

Soft Skills :

∙Strong analytical and problem-solving skills with attention to detail.

∙Excellent communication skills to present technical results effectively.

∙Ability to work collaboratively in multidisciplinary teams.

Preferred Qualifications :

∙Experience with mission planning for CubeSats, small satellites, constellations or flight formation.

∙Familiarity with interplanetary mission design and deep-space navigation techniques.

∙Understanding of emerging technologies in autonomous spacecraft navigation and

operations.

This position offers the opportunity to play a critical role in shaping innovative satellite

missions. If you're passionate about advanced orbital mechanics and mission design, we

encourage you to apply.
