Thermo-mechanical Engineer

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

The heart of a spacecraft lies in its engines, and that's why we, at The Exploration Company, are dedicated to developing our own cutting-edge Propulsion Systems ensuring the highest level of efficiency and reliability in our space endeavours.

We are seeking a talented Thermo-mechanical Engineer to join our Future Project division. As a key member of our engineering team, you will be responsible for designing, analyzing, and optimizing combustion devices for cryogenic rocket engines, with a focus on the main thrust chamber assembly.

Key Responsibilities

• Support structural and thermal analysis of combustion device hardware including injector heads, faceplates, combustion chambers, manifolds, and structural interfaces.

• Perform finite element analysis (FEA) and establish practical design suggestions and establish design recommendations, and margin assessments for hardware development.

• Develop and apply analytical and reduced-order models to estimate heat transfer, structural loads, and thermal boundary conditions to inform design trades and hardware maturation.

• Support hardware development and maturation, including design iteration, development planning, test definition, and post-test assessment of structural and thermal performance.

• Drive life assessment activities, including low-cycle fatigue, thermal fatigue, cyclic loading, margin tracking, and damage accumulation for reusable hardware.

• Own structural reliability and lifecycle assessments of combustion hardware, including low-cycle fatigue, thermal fatigue, cyclic loading, and thermo-mechanical failure risk evaluation.

• Collaborate with combustion and fluid engineers to translate predicted heat flux distributions, pressure fields, and flow characteristics into structural and thermal design requirements

• Define structural and thermal instrumentation strategies for development testing and participate post-test data reduction, model validation, and correlation activities.

• Contribute to material selection and design trades considering temperature capability, strength, fatigue resistance, oxidation compatibility, and cryogenic behavior.

• Prepare technical documentation and contribute to design, and test reviews with clear technical justification and risk assessment.

What we would love to see from you

• Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related technical discipline.

• Experience (academic, internship, or professional) in structural or thermal analysis of high-performance mechanical systems.

• Strong fundamentals in solid mechanics, heat transfer, and pressure-loaded structures.

• Experience with FEA tools such as ANSYS, NASTRAN, Abaqus, or equivalent.

• Ability to interpret complex thermal and pressure boundary conditions and apply them appropriately in structural models.

• Understanding of fatigue, temperature-dependent material behavior, and nonlinear structural response.

• Exposure to high-temperature or cryogenic systems is advantageous.

• Familiarity with CAD (NX ideally) tools and ability to work directly with geometry.

• Experience with Python or similar scripting tools for analysis automation or data processing is beneficial.

Skills and Behaviours

• Methodical and structured approach to problem solving.

• Strong attention to detail and analytical rigor.

• Clear written and verbal communication of technical rationale.

• Ability to iterate analyses as design and test data evolve.

• Interest in propulsion systems and combustion device development.

• Demonstrates behaviors consistent with The Exploration Company’s core values of Mission, Vision, Integrity, Excellence, and Teamwork.
