Propulsion Test Engineer

Here at The Exploration Company, we are building innovative aerospace technologies that advance the future of space transportation.

We are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit, and which carries cargo – and potentially humans in the long run. We are also developing different types of propulsion systems to power our future vehicles and missions. As a talented Propulsion Test Engineer, you will be responsible for the test and analysis of our future propulsion systems.

Key Responsibilities:

In your capacity as a Propulsion Test Engineer, your role will be continuously evolving, but day to day your duties will include:

• Prepare and execute tests at the engine and component level to evaluate hardware performance.
• Developing test plans, test objectives and schedules consistent with requirements and timelines; leading daily test operations and generating test reports.
• Autonomously leading risk assessment analyses and defining mitigation actions to ensure personnel and hardware safety during all test campaigns.
• Interpreting P&IDs and generating test sequences, balancing the risk, needs of the test and the limits of the test bench and test article.
• Working hand in hand with development engineers, test bench team, AIT team and external partners to support all test operations on internal and external test facilities.
• Supporting rapid test data processing with component development engineers to guide the remainder of the test campaign and plan future test campaigns.
• Defining, developing and updating test procedures and guidelines to improve test operations.
• Preparing technical documentation, including detailed procedures, test reports, design reviews, and performance analyses.

What we would love to see from you:

• Bachelor's, master's or PhD in aerospace engineering, mechanical engineering, or a related field (master's and above preferred).

• 3–5 years of experience in propulsion testing or related fields.

  • Proficiency in propulsion chemistry, thermodynamics, and fluid dynamics.
  • Proven hands-on experience with engine testing or equivalent.
  • Background in cryogenic propulsion will be a big plus.

• Experience with commonly used simulation tools in propulsion testing (e.g., CEA).

• Proficiency in python programming language is a plus.

• Exposure to CAD Software (Siemens NX, CATIA, or similar) and Geometric Dimensioning and Tolerancing.

• Strong problem-solving and analytical abilities.

• Excellent communication and leadership skills, with the ability to convey complex concepts to diverse audiences.
