Role overview :

As a Trajectory Optimization Intern, you will join our Mission Design & Flight Dynamics team to help design, simulate, and optimize multi-phase launch vehicle trajectories for precise orbital insertion. This includes optimizing each mission segment — first stage ascent, second stage ascent, and final orbit, ensuring optimal performance and robustness across all phases. An internal optimization method already exists. Your primary mission will be to significantly reduce its computation time while maintaining accuracy and robustness. 

You’ll evolve hand-in-hand with mission analysts and guidance engineers to develop efficient, feasible, and high-performance flight profiles for our launch vehicles Baguette One and OB-1. This is an opportunity to gain hands-on experience in high-stakes space mission design, applying advanced optimization techniques to real-world, multi-phase launch scenarios. 

Your key responsibilities :

As part of your internship and in direct connection with your academic training, you will be involved in the following missions :

• Develop, implement, and significantly reduce the computation time of the existing in-house trajectory optimization method for multi-phase launch trajectories.
• Perform mission analysis to define orbital insertion requirements for each flight phase.
• Simulate ascent and orbital phases (first stage, second stage, transfer burns) using in-house and industry-standard tools. 
• Analyze trade-offs between performance, robustness, and mission constraints across all phases.
  
• Document and present your work to support mission reviews and decision-making.
• Collaborate with GNC, propulsion, and systems engineering teams to ensure optimized trajectories are technically feasible.
• Participate in validation campaigns and sensitivity analyses to assess mission robustness. 

Who we are looking for :

You are an aspiring aerospace engineer passionate about space mission design, numerical optimization, and the challenges of multi-phase trajectory planning. 

• Bachelor’s or Master’s degree student in Aerospace Engineering, Applied Mathematics, or a related field.
• Solid foundation in orbital mechanics and astrodynamics.
• Proficiency in a scientific programming language (Python, MATLAB or C++).
• Familiarity with numerical optimization techniques: Direct Shooting Method,
• Indirect Shooting Method (Pontryagin’s Maximum Principle etc).
• Understanding of launch vehicle performance metrics and constraints. Strong analytical mindset, attention to detail, and problem-solving skills.
• Ability to work collaboratively in a multidisciplinary team.
• Bonus points if you have: Experience with parallel computing or GPU acceleration for optimization. 

Why joint us ?

• Work on real-world, multi-phase space mission trajectory optimization problems.
• Gain hands-on experience with cutting-edge optimization and simulation tools.
• Collaborate with passionate engineers working towards ambitious spaceflight goals.
