Here at The Exploration Company, we are building spacecrafts for humanity.

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 which carries cargo - and potentially humans in the longer run.

We are seeking an experienced and talented Storm Test Bench Principal Engineer, to lead the development of one of the most powerful European cryogenic test bench for 2.5MN class engines.

This is a key leadership role that requires deep technical expertise in liquid-propellant propulsion systems, a proven track record managing complex engineering projects, and experience leading and mentoring technical teams. As Storm Test Bench Principal Engineer, you will ensure that test bench development is carried out safely, efficiently and with technical rigor, from design through commissioning and system-level testing. You will provide technical direction to the testing team, coordinate priorities and resources, resolve complex technical issues, and ensure the test bench meets its performance, quality, schedule and safety objectives.

The role combines technical leadership, people leadership and hands-on involvement in preparing and executing complex cryogenic propulsion test campaigns.

Key Responsibilities / Tasks

Provide overall technical leadership for the test bench development

Define and maintain the development approach, philosophy, plans and technical execution strategy

Ensure that test bench capabilities are aligned with system requirements, design intent, verification objectives and programme milestones

Lead the technical assessment and resolution of complex test problems, including test anomalies, hardware issues, instrumentation problems and system performance deviations

Coordinate the investigation of anomalies and ensure that root-cause analysis, corrective actions and retest activities are properly managed

Ensure that the test bench design performed in accordance with applicable safety rules, operational constraints and approved procedures

Support the development of the teams through coaching, technical guidance and constructive feedback

Build a culture of ownership, disciplined execution, continuous improvement and learning from experience

Contribute to integrated project planning, including test schedules, resource requirements, facility usage and major test milestones

Identify technical, operational and schedule risks related to test activities and ensure that mitigation actions are defined and implemented

Ensure compliance with company processes and applicable regulatory requirements for cryogenic propulsion test activities

Promote a strong safety culture, particularly for activities involving cryogenic propellants, high pressure, hazardous energy and propulsion test operations

Required Qualifications & Skills

Degree in mechanical engineering, aerospace engineering, propulsion engineering or a related technical discipline

Proven professional experience (5+ years) in spacecraft, launch vehicle, aircraft, industrial gas, energy or another relevant high-technology environment

Experience in cryogenic propulsion systems testing

Proven experience leading engineering teams and coordinating multidisciplinary technical activities

Experience with cryogenic systems, liquid propulsion, pressurised systems, fluid systems or related test operations

Experience planning and executing complex test campaigns from test preparation through final reporting

Demonstrated ability to lead technical investigations and resolve test anomalies using structured problem-solving methods

Experience working with test facilities, ground support equipment, instrumentation and data acquisition systems

Capacity to travel to test sites and partner facilities as required

Excellent written and verbal communication skills

Fluent professional English. French will be an advantage
