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.

We are also 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 Nyx Test Bench Engineer, you will be part of the team that develops the 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 be part of the team that develops, commissions and operates the test facility.

Key Responsibilities / Tasks

Design of Test Facility

• Supporting development of a vacuum hot fire test facility which will be used to develop and qualify orbital thrusters - in tandem with the main designer/team leader

• 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 teams, customers, and external partners.

Assembly & Integration of Test Facility

• Manage suppliers and manufacturing activities; support in integration and verification.

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

Safety & Operation of Test Facility

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

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

• Integration of thruster into test bench

• Support operations of test facility and perform hot fire, cold flows, decontamination and maintenance activities

• Perform maintenance activities of the test facility

What We Would Love to See From You

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

• 2+ 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.

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

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