Combustion Engineer Verified today

The Exploration Company · Bordeaux, France · Propulsion · first seen 2026-08-05

The Exploration Company is developing Nyx, a modular reusable space orbital vehicle that can be refuelled in orbit and carry cargo and potentially humans. We are building cutting-edge propulsion systems to power this vehicle.

We seek a Combustion Engineer to join our Future Project division, responsible for designing, analyzing, and optimizing combustion devices for cryogenic rocket engines.

Key Responsibilities

  • Support combustor fluidic system development using theory and CFD
  • Drive and contribute to injector design and optimization against combustor requirements using theory and CFD
  • Support instrumentation definition for hot-fire testing and assist with post-test data interpretation and CFD/model correlation
  • Reduce and analyse hot-fire test data to derive performance and combustion-stability metrics, and maintain associated data processing tools
  • Support design reviews with clear technical justification of analysis methods, assumptions, and margins

Requirements

  • Master's degree in Aerospace Engineering, Mechanical Engineering, or related discipline
  • 3+ years of relevant experience in combustion, propulsion, or reacting-flow engineering
  • Solid foundation in bi-liquid rocket combustion processes
  • Strong background in reacting-flow CFD (e.g. ANSYS, OpenFOAM, Converge) using RANS and/or LES
  • Strong scripting and data-analysis ability in Python or similar
  • Exposure to liquid rocket injector CFD
  • Experience with combustion of cryogenic propellants
  • Familiarity with combustion instability, thermoacoustics, or uncertainty quantification is beneficial
  • Experience supporting or participating in hot-fire test campaigns is beneficial

Skills and Behaviours

  • Structured and methodical approach to problem solving
  • Demonstrated rigour: checks reference calculations, documents assumptions, and treats discrepancies between prediction and test as problems to solve
  • Ability to work under technical uncertainty and iterate models as test data becomes available
  • Clear written and verbal communication of assumptions, methods, and conclusions
  • Comfort working in cross-disciplinary teams across thermo-mechanical, systems, and test engineering
  • Strong analytical rigor and attention to detail

Relocation assistance and visa sponsorship are available where applicable. All offers are contingent upon successful completion of a background check.
