AIT Thermal / ECLSS 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. We are seeking an experienced AIT Thermal/ECLSS Engineer to join our dynamic AIT team. In this role, you will be responsible for the planning, execution, and analysis of both thermal and ECLSS test campaigns and their system-level integration for Nyx Earth and its demonstrator vehicles. This is a unique opportunity to play a hands-on role in testing and qualifying critical space systems in a fast-paced, innovation-driven environment. You will report to the AIT Mechanical Principal Engineer. KEY RESPONSIBILITIES: - Integration & Test Planning: Design and plan thermal test campaigns (Active Thermal Control System (ACTS), TVAC, thermal balance, thermal cycling) for system and sub-system levels. Design and plan ECLSS test campaigns (e.g. Pressure Compartment System, Ventilation system, etc..) for system and sub-system level. Support the preparation of engineering drawings for manufacture of test bench components. - Hardware Management: Define and manage flight hardware interfaces during integration (pipes, fittings, valves, MLI, heaters, sensors, harness routing, thermal fillers, etc.). Design the 3D setup of test activities and build test setup. Procure test parts and write/execute procedures for all test activities. - Test Execution: Plan, define, prepare, execute, and oversee thermal/ECLSS tests in coordination with internal and external test facilities. - Data Analysis & Reporting: Provide test results and generate comprehensive test reports. Support in correlate and validate models in collaboration with engineering team. - Cross-functional Collaboration: Work closely with the design office and systems engineering to ensure design meets flight qualification standards. Support the AIT team to write other mechanical procedures for structure assembly or test setups. Improve the processes and procedure with the lessons learned of the previous operations. Support the team in other factory setup as we are a growing company, the perimeter can evolve along the mission. - Compliance & Safety: Ensure all testing activities comply with spaceflight standards and internal quality/safety protocols. WHAT WE WOULD LOVE TO SEE FROM YOU: - A minimum of a MSc degree in Aerospace Engineering, Mechanical Engineering, Thermal Physics, or related field. - Over 3 years of relevant experience in testing or integration in the aerospace sector. - Strong understanding of spacecraft thermal control systems, ECLSS systems, and test methodologies. - Hands-on experience with TVAC chambers, thermal cycling equipment, sensor systems and test bench setup, including pipe bending. - Familiarity with instrumentation (thermocouples, RTDs, thermal blankets, heaters, pressure sensors, actuators, etc.). - Experience in writing and executing test procedures and managing test campaigns. - Experience with CAD software preferably with Siemens NX - Excellent problem-solving skills, autonomy, and attention to detail. - Fluency in English.
