Back to jobsSenior Fluid Systems / Process Design EngineerOttobrunn, Bavaria, GermanyApplyMission Brief  We deliver the half of the rocket that stays on the ground. As a Senior Fluid Systems Design Engineer at the Ground Systems department of Isar Aerospace, you deliver the ground fluid infrastructure required for safe, reliable, and rapid test and launch of the Spectrum rocket. This includes test-rigs for development, qualification, and acceptance of launch vehicle and propulsion systems as well as entire launch bases. You work hand-in-hand with Propulsion and Launch Vehicle development teams to translate their requirements into functional designs and concepts of operations. You tackle complex engineering challenges across multiple projects and phases – from concept to detail design, execution, commissioning, and handover to site owner and operator.       Your Role in Our Space Mission:  Design fluid systems for test and launch facilities, including rocket engine test-rigs, structure pressurization test-rigs, integrated stage testing rigs, launch pads, etc.  Perform sizing calculations and/or numerical simulations for fluid systems, including cryogenic propellants storage, conditioning, and distribution systems, high-pressure gas distribution and pressurization systems, etc.  Select and procure suitable fluid hardware, including tanks, pumps, heat-exchangers, valves, pressure regulators, safety-valves, instrumentation, etc.  Prepare technical documentation, such as PFDs and P&IDs, hardware lists, datasheets, etc. that serve as a basis for manufacturing planning and execution  Lead and contribute to system design reviews and risk assessments, ensuring safety, reliability, and compliance  Act as a technical point of contact and subject matter expert for the projects and operations teams, consulting on fluid system questions and decisions  Mentor junior and mid-level engineers and contribute to structuring and expanding knowledge in the team with guidelines, checklists, processes, presentations, etc.  Depending on interest and experience:  Lead or support factory and site acceptance tests for fluid systems  Lead or participate in commissioning planning and hands-on site operations   Support test and launch campaigns on-site or remotely with operations or data analyses.    Qualification Checklist  Education and Experience:  B.Sc. or M.Sc. degree in process/energy/chemical/aerospace/mechanical engineering or an equivalent qualification  At least 5 years of relevant professional experience in aerospace, oil & gas, energy, chemical industry, engineering service provider or similar  In-depth experience in the design and/or operation of high-pressure gas and cryogenic liquid systems, ideally, in the context of rocket testing and launching facilities  Experience with design and safety analyses and reviews, including HAZOPs  Hard Skills:  Expert knowledge of fluid mechanics and thermodynamics and their application to real hardware like valves, regulators, etc.  Strong analytical skills and able to apply theoretical knowledge to find practical solutions to complex fluid mechanic and/or thermodynamic engineering problems  In-depth knowledge of industry standards and technical regulations which are common in plant engineering (e.g. ASME, ISO, DIN EN, PED, AD2000, ATEX)   Modeling and simulation of fluid systems by means of software such as EcosimPro, Python/Matlab scripts, and Excel sheets  Soft Skills:  Adjusting self-sufficiently and quickly to a changing work environment, supporting the team  Highly organized, effective team player with high attention to detail  Proactive, open, effective, and constructive communication also in stressful situations  Can-do attitude and desire to go out of your way to help others  Available for occasional international travel to our test and launch sites  Language  Fluent in English    Bonus Skills  Hands-on experience with fluid systems, e.g., assembly of piping systems,...
