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

We are seeking a skilled

Senior

Flight dynamics Engineer / Mission Design Engineer

to join our team, specializing in the design, analysis, optimization of satellite orbits and fine-tuning the mission profile from the beginning to end of life for the range of our upcoming spacecrafts.

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.
