[Nyx Earth] Propulsion CAD 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 Propulsion Structural Engineer, you will be responsible for the design, justification, testing and validation of the mechanical structure of the propulsion system and its interfaces with the primary structure. ROLE OVERVIEW Structural Analysis & Technical Ownership * Review static and dynamic load inputs, material properties, test data, and component requirements to properly set up structural analysis cases. * Produce stress and fatigue analysis results with detailed validation methodologies and rigorous justification of the propulsion system's structural margins, applying the standards (including fracture control) required for NASA certification. * Assess the integration of of-the-shelf equipment to the propulsion system within the overall system considering their qualified loads * Own the structural substantiation of propulsion components and structures from concept through qualification, ensuring traceability between requirements, analysis, and test. * Design Collaboration & Mechanical Development * Work closely with design engineers to validate mechanical sizing and help them iterate through designs as efficiently as possible. * Design simple mechanical components from scratch and propose creative structural solutions to design engineers, drawing on analysis results and hands-on experience. * Support trade studies on structural architecture, materials, and joint design for propulsion structures and brackets. * Test Campaign Development & Support * Develop and support hardware test campaigns — coupon or sub-assembly testing — to gather analysis inputs or validation data. * Define test objectives and success criteria in coordination with test engineering, and correlate test results back into analysis models. * Identify appropriate test platforms and instrumentation needs for structural verification. * Support non-conformities analyses and resolve process * Anomaly Investigation & Non-Conformance Management * Act as a key contributor to anomaly investigations, performing root cause analyses on structural damage or unexpected test/flight behavior. * Justify non-conformities against structural requirements and support disposition decisions with sound engineering rationale. * Feed lessons learned from anomalies back into design standards and analysis practices. 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 * 5+ years of hands-on experience in structural analysis for launch vehicles, spacecraft, or space capsules, ideally with exposure to liquid propulsion structures and systems. * Strong command of FEA tools (NASTRAN or equivalent) complemented by solid hand-calculation skills, for both static and dynamic (vibration, shock, fatigue) load cases. * Familiarity with the standards and processes required for structural certification (e.g. NASA-STD-5001, ECSS, or equivalent), and experience producing analysis reports that hold up under formal review. * Working knowledge of CAD environments (CATIA, NX, or equivalent), sufficient to review, sketch, and propose mechanical design changes. * Experience supporting or running test campaigns, from test definition through correlation of results with predictions. * A track record of contributing to anomaly investigations or non-conformance dispositions in a hardware-delivery environment. 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.

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 Valve Development Engineer, you will lead the design and development of solenoid isolation valves for our storable propulsion system, from concept through qualification — owning the electromagnetic, mechanical, and sealing design that makes the valve work reliably over the mission life. ROLE OVERVIEW Valve Design & Development * Support the design of solenoid isolation valves from concept through qualification, balancing performance, mass, reliability, and manufacturability. * Define and mature valve architecture — poppet/seat design, actuation mechanism, sealing concept — to meet functional and interface requirements. * Perform mechanical sizing and trade studies (force margins, spring rates, stroke, response time) to support design decisions. Electromagnetic & Actuation Design * Design and analyze the solenoid actuator — coil, armature, magnetic circuit — to meet response time, power, and force margin requirements. * Collaborate with electrical engineers on coil drive electronics and EMI/EMC considerations. * Support trade-offs between actuation force, power consumption, and thermal dissipation. Materials, Sealing & Propellant Compatibility * Select materials and seal designs compatible with storable propellants, ensuring long-term compatibility and low permeation/leakage. * Define sealing concepts — elastomeric or metal-to-metal — balancing leak-tightness, cycle life, and contamination sensitivity. * Coordinate with materials engineering on qualification of propellant-wetted materials. Design Verification & Cross-Functional Coordination * Define and support the verification plan for valve qualification, working closely with test engineers on test setup and success criteria. * Collaborate with manufacturing engineers to ensure design manufacturability and testability. * Support anomaly investigations and root cause analysis for valve-level issues, feeding lessons learned back into the design. 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 * 5+ years of hands-on experience designing valves or similar electromechanical fluid components for space or aerospace applications. * Experience in solenoid/electromagnetic actuator design (magnetic circuit design, coil design) is a strong plus. * Strong understanding of sealing technology, elastomer and metal seal design, and propellant compatibility; storable propellant experience preferred. * Proficiency in CAD (CATIA, NX, or equivalent) and mechanical analysis tools. * Experience defining and supporting qualification test campaigns for valves. * Familiarity with applicable standards for valve qualification (NASA, ECSS, or equivalent).
