About Catalyx Space:

Catalyx Space is building the world's best reentry systems. Our reusable ReX vehicles return payloads from orbit at unprecedented scale, up to 12 tons and 60m³ of cargo, while operating the full mission lifecycle from launch to recovery. Our core innovation is a Origami-inspired deployable heat shield that combines the scalability of an inflatable system with the robustness of a rigid structure. Built from commercial off-the-shelf components, it enables the world's widest heat shields, the largest payload return volumes, and a scalable pathway for returning everything from commercial cargo to future space nuclear assets.

Role:

Catalyx Space is looking for a Flight Dynamics Engineer to build and run trajectory simulations, predict landing zones, and define performance envelopes for reentry missions. You will work closely with Aerodynamics, Systems, Propulsion, and GNC teams to ensure vehicles perform as designed across mission phases.

Responsibilities:

• Develop and maintain trajectory simulation tools using Python, MATLAB, or similar tools
• Design reentry trajectories and evaluate vehicle performance
• Estimate landing zones and downrange footprints
• Work with aerodynamics teams to model moments and aerodynamic coefficients
• Create vehicle envelopes and safety corridors
• Provide burn timing and attitude profiles for mission planning
• Support actuator and control-surface sizing
• Own the mission delta-V budget
• Interface with internal operations teams, hardware teams, and external regulatory partners such as FAA or DGCA
• Participate in multidisciplinary vehicle systems investigations to support mission design, vehicle architecture, and analysis methodology

Qualifications:

• Bachelor's or Master's degree in Aerospace Engineering or a related field
• 3+ years of professional experience in trajectory analysis, orbital mechanics, and modelling and simulation
• Strong understanding of orbital mechanics, flight dynamics, and reentry trajectories
• Experience with numerical simulation tools such as Python, MATLAB, or C++
• Hands-on experience with STK and GMAT
• Experience building or working with 6-DOF trajectory models
• Familiarity with aerodynamic databases and trajectory modelling
• Comfortable working across teams including Aerodynamics, Structures, and GNC

Nice to have:

• Demonstrated project or professional experience in spacecraft systems
• Strong written and verbal communication skills
• Flexibility to support extended hours or weekend work during critical mission phases

Compensation & benefits:

• Competitive salary (details will be shared with shortlisted candidates), 
• health insurance
• Provident fund.
