Company Overview

Bellatrix Aerospace is a leading space transportation company dedicated to developing innovative technologies that shape the future of our industry. With a focus on propulsion systems and in-orbit transportation solutions, we strive to create a better tomorrow.

Estimated Salary: ₹ 10-15 lakhs per annum (depending on experience)

Job Description

We are seeking an experienced 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.

Key Responsibilities

  • Design and analyze satellite orbits and model relevant maneuvers for various missions, including LEO, MEO, GEO, and interplanetary trajectories.
  • Develop and optimize orbital transfer strategies, station-keeping maneuvers, 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

To be successful in this role, you will need:

  • 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.
  • 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.
  • 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).

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.
