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 want you as a talented Supply Chain Manufacturing Engineer (Metals) to help us in our mission by supporting the design team to build up the Nyx vehicle. As process engineer you will: * Work together with the mechanical and design units to support through our supply chain the manufacturing of complex metallic structures, * You will work closely with the product assurance and procurement team to help controlling the quality of the final delivered products. KEY RESPONSIBILITIES You will have a key responsibility at the technical crossroad between vehicle design team, product assurance team and procurement team. Your role will be continuously evolving, but day to day your duties will include: * Taking responsibility for technical exchanges with suppliers about manufacturing of metallic structural parts. Under the intended product owner guidance you act as a technical liaison between the company and its suppliers, facilitating clear and open communication to address any manufacturing related issue promptly. * Monitoring suppliers industrial process, and if necessary propose improvements, to make sure the final product meets the requirements. * Supervising supplier's development roadmaps from TRL 4-5 up to TRL 9, assuring the proper technology development. * Partnering with the Product Assurance team to monitor supplier quality control plans, required standards, specifically focusing on NDT (Non-Destructive Testing) and material certifications. * Collaborating continuously with engineering team and suppliers to accomplish the delivery of final products, from engineering models up to final flight models, in accordance with schedule. * Supporting suppliers to analyse and improve their industrial processes, considering challenges of large-scale machining, sheet metal bending, additive manufacturing, and specialized joining (e.g. welded structures). * Supporting the procurement and engineering team with technical discussions with suppliers. * Documentation for the various reviews (TRL review, PDR, CDR, QR, MRR) * Generating technical reports and presentations to communicate findings and recommendations to stakeholders. WHAT WE WOULD LOVE TO SEE FROM YOU * Bachelor's or master's degree in Aerospace engineering, Material and Processes engineering, Mechanical engineering or any related area. * At least 7 years of experience as manufacturing engineer, focus on space-graded metallic components is mandatory. * Deep knowledge of high-performance alloys (Aluminium, Titanium, Inconel) and manufacturing methods such as 5-axis machining, sheet metal bending, coating, heat treatment, ALM (Additive Layer Manufacturing), and forging. * Significant experience in the manufacturing of welded metallic structures (e.g., TIG, Electron Beam or Friction Stir Welding) and the associated inspection standards. * Familiarity with spacecraft primary structures, pressure vessels, or re-entry vehicle hardware is a major asset. * Excellent problem-solving skills and attention to detail as well as organizational skills. * Effective communication and teamwork abilities. * Ability to collaborate with multidisciplinary teams (Design, AIT, Product Assurance, Procurement). Why you should join us! What makes us special here at The Exploration Company and why we think you will enjoy working here is: * We’re Agile - we make decisions fast whilst keeping our goals and systems in mind * We’re Open and Collaborative - we are transparent about risks and obstacles, so that we can cooperate to overcome them * We have a lot of Fun - we refuel our energy knowing we are democratising space.

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 want you as a talented System Integration Senior Engineer to help us lead the system end‑to‑end integration and verification of functional and environmental elements within the Nyx spacecraft, ensuring full compliance with system‑level requirements and standards. In this role, you will coordinate the integration of mechanisms, structural assemblies, deployment systems, and mechanical‑to‑avionics interfaces, driving the verification logic from early functional modelling through environmental qualification and final acceptance. You will define and execute plans, manage requirement traceability, analyse results, and close verification evidence campaigns. Working closely with subsystem leads, AIT teams, and external partners, you will identify integration risks, resolve anomalies, and ensure that all mechanical functions perform safely and reliably throughout the mission profile. This position requires a rigorous systems mindset, strong understanding of mechanical behaviour in the space environment, and the ability to lead multidisciplinary verification activities to successful closure. Key Responsibilities In your capacity a System Integration Senior Engineer, your role will continuously evolve, but initially your day-to-day duties will include: * Ensure the definition and implementation of the Nyx Earth system integration and verification activities, which meets technical and programmatic requirements and considers the adequacy of model philosophy, facilities availability, planning and costing. * Define plans and specifications with clear Success Criteria and support the generation of test procedures with the functional team. * Drive the technical discussions, preparation, organization and execution of the system verification campaigns, to ensure the closure of all system verification aspects, including nominal and off nominal spacecraft behaviors. * Organise the different reviews for incremental progress and ultimate closure of verification events. * Generate reports and drive the closure of the Items for Verification and Validation covered by the campaign. * Collaborate with all Functional Chain responsible and engineering disciplines to prepare and perform the system activities. * Process the anomalies occurring during the verification campaign in coordination with the Product Assurance Team and the rest of the Engineering Team. What we would love to see from you In the role of System Integration Senior Engineer ideally, you will have the following: * Master’s degree in Aerospace Engineering, or another related field. * 5 to 10 years of experience in systems design, analysis, and testing of aerospace or space-related systems, with a focus on integration of complex spacecraft and/or testing activities. * Hands-on hardware experience. * Practical experience / contact with functional test platforms, such as software in the loop, hardware in the loop, and bench testing. * Experience in the development and verification of space hardware. * Spacecraft systems knowledge.
