System Integration Senior Engineer (Functional Focus)

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.

Skills and Behaviours

• Strong oral and written communication skills

• Strong analysis and problem-solving skills

• Strong organizing and prioritization of tasks
