Senior Flight Dynamics Engineer

Company Overview

Bellatrix Aerospace is a new age space mobility company that develops and manufactures advanced propulsion technologies for a wide range of missions, from deploying and phasing satellite constellations to ferrying multi-ton communication satellites to the geo-stationary orbit.

Job Summary

Senior

Job Responsibilities

• Design and analyse satellite orbits and model relevant manoeuvres for a variety of missions, including those to LEO, MEO, GEO, and interplanetary destinations.
• Assist in the process of satellite navigation, orbital transfer strategies, station-keeping manoeuvres, and end-of-life de-orbit planning.
• Perform high-fidelity simulations of satellite missions using self-developed scripts and trajectory models required for FoV studies, sunlight illumination analysis and ground station visibility as dictated by the requirements coming from GNC, Power, Thermal and RF communication subsystems.
• Collaborate with Systems Engineer to integrate orbital designs into mission plan architectures.
• Conduct trade-off studies to evaluate mission scenarios, optimal trajectory selection, and propulsion needs for keeping delta-v budget minimized.
• Generate detailed reports and visualizations of mission analyses to support decision-making in the mission operations of the spacecraft.

Qualifications

• Bachelor's or Master's degree in Aerospace Engineering, Astrodynamics, Physics, Mathematics, Optimal Control Theory or a related field. A Ph.D. in the relevant field is a plus.
• 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).

Technical Skills

• Strong expertise in orbital mechanics, optimal control theory, multi-body dynamics, and relative motion in space.
• Proven experience in

  orbit optimization

  , including expertise in orbital transfer strategies, optimal control theory, Lambert solvers and delta-v minimization.
• 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.

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.
