[Nyx Earth] System Functional 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. As a talented System Functional Engineer, you will be responsible for maturing the propulsion fluid system's functional design and performance models from preliminary to detailed design, and for driving the architecture trades, verification, and requirements work that keep the system compliant, safe, and traceable. ROLE OVERVIEW FLUID SYSTEM DESIGN & FUNCTIONAL ANALYSIS - Mature the overall fluid system from detailed design to qualification by leading the functional analysis of the assembly - Lead your own analysis tasks using advanced simulation tools, and provide outputs to other fluid analysts and functional engineers in selecting appropriate methodologies, assumptions, and data processing methods. - Ensure functional analysis outputs feed directly into design maturity, keeping the fluid system design compliant and traceable as it advances toward detailed design. System Architecture & Trade Studies - Contribute to the evaluation and optimization of propulsion system concepts in terms of performance, mass, operations, cost, and reliability/safety. - Support development and qualification ground platform designs - Contribute to ground platforms and flight simulations, sensitivity analyses, and risk assessments. Performance Modeling & Verification & Validation - Develop and maintain functional performance models of propulsive systems using simulation frameworks such as EcosimPro and Python-based codes. - Validate and anchor models against available test data. - Plan and execute the V&V plan for the fluid subsystem, including analysis and test campaigns to verify subsystem performance and requirements compliance. Failure Analysis, Sequencing & Requirements Management - Contribute to FMEA (Failure Mode and Effects Analysis) to ensure the system architecture is consistent with reliability and safety targets. - Support the Concept of Operations of the Functional Propulsion System in accordance with engine needs and constraints. - Contribute to functional requirements for subsystems such as valves, and tanks based on propulsion system analyses. KEY RESPONSIBILITIES LOCATION You will perform your duties principally at the Company's premises in Bordeaux and may be required to travel from time to time to our company’s premises in Munich in the course of your duties. WHAT WE WOULD LOVE TO SEE FROM YOU - Master’s and/or PhD degree in Aerospace Engineering or a related field - Proven experience with 0D - 1D fluid simulation tools (model development and analyses) - (e.g., EcosimPro, Amesim) - Deep understanding of fluid mechanics, heat transfer, and compressible flow - Experience with storable propulsion system is a plus - Fluency in English; proficiency in Italian, German or French are an asset Skills and Behaviors: - A hands-on approach to problem-solving, combined with a collaborative mindset to work across multidisciplinary teams - Excellent organizational skills and ability to multitask - Capability of working autonomously whilst collaborating productively with remote teams - Positive and flexible attitude in a constantly evolving environment - Grit to get the job done - Ability to communicate effectively with a wide variety of audiences - Behaviors consistent with The Exploration Company’s core values of Commitment, Innovation, Trust, Quality, and Teamwork 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. It’s a wonderful and rare opportunity…
