As a Test Technician , you will be directly involved in the core of our propulsion development efforts. You will prepare and operate our vacuum test facilities, work hands‑on with real hardware, and support engineers during key testing campaigns. Your work will contribute directly to validating components and subsystems that will fly in space, becoming an essential part of our experimental and testing operations. Location: Porto do Molle, Nigrán. What You Will Do: Prepare and condition vacuum chambers for propulsion testing. Execute and supervise experimental tests, ensuring compliance with procedures and safety standards. Support laboratory and experimental activities across different engineering teams. Assist in the design, setup and maintenance of vacuum chambers and cleanroom infrastructure. Assemble propulsion subsystems: sensors, gas lines, structural components. Perform manual workshop tasks (cutting, assembly, basic machining). Maintain test equipment and facilities in optimal operating condition. Follow safety protocols for gases, vacuum systems and high‑voltage equipment. What You Bring: Essential: Experience using measurement and control instrumentation. Strong hands‑on skills: cutting, assembling, basic machining. Knowledge of safety procedures for high‑voltage systems, fluids and gases. Ability to communicate in English (spoken and written). Nice to have: Experience with vacuum chamber design/assembly/operation. Knowledge of cleanroom environments and operational standards. Experience mounting sensors (e.g., thermocouples, pressure sensors) and propulsion‑related components. Your Strengths: Teamwork in multidisciplinary environments. Adaptability to support diverse tasks. Proactive approach to solving technical issues. Attention to detail and strong adherence to procedures. Work on cutting‑edge electric propulsion technology. High‑impact, hands‑on role with real hardware that will reach space. Young, international and highly technical team. Fast career growth as the company and testing team scale. Be part of one of Europe’s most promising aerospace deep‑tech startups.
