  • Perform in-depth data and performance analysis with a focus on iterative design and improvement.
  • Prepare technical reports, qualification matrices, and compliance documentation in line with military and aerospace standards.
  • Develop tools and methodologies for the development, analysis, or performance estimation of our rocket motors.
  • Support the development of Thermal Protection Systems (TPS), nozzle, and rocket motor sizing tools.
  • Assist in the design for qualification and certification of rocket motors in accordance with MIL-STD and STANAG standards.
  • Collaborate closely with design engineers on motor hardware design, insulation, and igniter integration to ensure certifiability from the start.
  • Support failure investigations, root cause analyses, and updates to design or test procedures to maintain compliance.
  • Work with internal teams and external partners to align design validation and certification timelines.

Requirements - What You’ll Need

  • Master’s degree in Aerospace, Mechanical, or Propulsion Engineering.
  • Minimum of 4-5 years of experience in rocket motor development.
  • In-depth knowledge of design and sizing of rocket motors and thermal protection systems.
  • Previous experience with coding and tool development.
  • Experience qualifying rocket motors or ignition safe and arm devices according to NATO standards is a plus.
  • Hands-on experience with static firing tests, propellant handling, or motor integration.
  • Familiarity with pressure vessel design and combustion analysis is advantageous.
  • Strong analytical and documentation skills — able to interpret data, write clear test reports, and maintain compliance records.
  • Comfortable working across disciplines — mechanical, thermal, materials, and systems engineering.
  • Willingness to travel to various Destinus sites in Switzerland (maximum 20%).
