Propulsion Thermal Engineer

The Exploration Company

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 are looking for a Mission Assurance Engineer to own the end-to-end strategy that ensures our spacecraft is safe, reliable, and mission ready. In this role you will be embedded with the design, test, and operations teams, driving the vehicle safety architecture as well as relentlessly driving risk down and availability up. KEY RESPONSIBILITIES * Ownership of the vehicle safety architecture making sure it meets all safety & reliability requirements (both internal and external from ISS program, ESA and CNES on entry safety). * Responsible for assessing pre-flight risks and potential mitigations with vehicle design, analysis, and operations teams. * Perform and review FMECA, FTA, PRA, and RAM analyses to identify risks and failure modes. * Define and validate the spacecraft fault management and FDIR architecture. * Work with avionics, software, and operations teams to implement fault management strategies and ensure safe behavior under off-nominal conditions. * Support on-console operations as the Mission Assurance representative and drive in-flight anomaly resolution. Ensure lessons learned feed directly back into design and FDIR improvements. * Champion a culture of mission assurance. Instill first-principles thinking, disciplined verification, and data-driven decision-making. * Report to program leadership on RAMS status, residual risk, and flight readiness. * Drive corrective actions from anomalies, test failures, and operational events back into design improvements. WHAT WE WOULD LOVE TO SEE FROM YOU The ideal candidate will have: * Master’s degree in an engineering or science discipline. * Proficiency with reliability tools (e.g., FMECA, FTA, reliability block diagrams). * Understanding of fault tolerance, redundancy management, and failure detection/isolation/recovery. * Technical knowledge of spacecraft systems and operations (e.g., communications, orbital mechanics, avionics, propulsion, thermal control, life support systems). * Strong written and verbal communication of technical information. * Able to effectively manage projects and tasks while meeting aggressive deadlines. * Thrives under pressure and is resilient in the face of technical challenges. * Excellent organizational and interpersonal skills. BONUS QUALIFICATIONS * Experience developing and validating FDIR logic, watchdog strategies, and fault response sequences. * Previous experience in a customer-facing role working through design requirements, test acceptance, and verification (especially with a government customer such as CNES/ESA/NASA). * Passion for advancing the commercial space industry and human spaceflight. 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.
