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 Fo V 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:
∙Bachelor’s or 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., Sci Py, CPLEX, or Gurobi) and
astrodynamics-specific toolkits (e.g., Orekit or Poliastro) is highly desirable.
Experience:
∙2+ 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 Cube Sats, 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.
