Vacuum Hotfire Test Stand Senior Engineer

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

In addition, we are developing advanced propulsion capabilities to support our reusable spacecraft programs. We are building a dedicated test capability for storable, hypergolic propulsion systems in the 100–800 N class.

As a Vacuum Hotfire Test Stand Senior Engineer, you will lead the end-to-end development of a propulsion test facility for legacy propellants (e.g., MON-class oxidizers and MMH-type fuels), from requirements definition through commissioning and operating the test facility. You will manage the team that develops, commissions and operates the test facility. This position requires technical excellence and expertise as well as team management skills.

Key Responsibilities

Design of Test Facility

• Develop a vacuum hot fire test facility which will be used to develop and qualify orbital thrusters

• Capture and define system-level requirements for a chemical propulsion test bench supporting 100–800 N thrusters.

• Define performance envelopes, safety objectives, operability constraints, and verification methods.

• Translate propulsion test needs into facility, utilities, and ground support equipment requirements

• Define instrumentation, data acquisition, and control systems for safe hot-fire testing.

• Interface effectively with internal engineering/design teams, customers, and external partners.

Assembly & Integration of Test Facility

• Define the schedule and conditions of the bench integration. Define the tests to be performed all along the project, to mitigate the risks to find issues during commissionning.

• Manage suppliers and internal manufacturing activities; oversee integration and verification.

• Plan and execute commissioning, acceptance testing, and entry-into-service activities.

Safety & Operation of Test Facility

• Lead hazard analyses (FMEA, HAZOP, risk assessments) and implement mitigation measures.

• Develop procedures for handling, testing, maintenance, and emergency response.

• Validate redlines and abort sequences for different failure cases

• Integration of thruster into test bench

• Lead operations of test facility and perform hot fire, cold flows, decontamination and maintenance activities. It's possible that at one point, the operations would be handover to another testing team and then insure a smooth and well documented handover if needed.

Leadership / Team management

• As a Team Leader we expect you to drive and support a small multidisciplinary team to design, procure, assemble, and install and commission the test bench.

• You will manage the team tasks and priorities and partially HR/training and developpement topics

What We Would Love to See From You

• Degree in aerospace, propulsion system, mechanical, chemical engineering, or a related discipline.

• 5+ years of hands-on experience with propulsion test benches, preferably with storable/legacy propellants.

• Strong background in fluid systems, pressurized systems, and ground support equipment.

• Demonstrated experience delivering complex engineering facilities from concept to commissioning.

• Knowledge of safety-critical systems, industrial automation, and test operations.

• Experience with site qualification, permitting, or regulated industrial environments.

• Excellent communication skills across technical and non-technical stakeholders.

• Experience in vacuum test facility design and operation

• Experience with team management would be a plus
