Job Description:

We deliver the half of the rocket that stays on the ground. As a Senior Ground Fluid Systems Engineer at 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.

Job Responsibility:

  • 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, technical notes etc. that serve as a basis for manufacturing planning and execution
  • Lead and contribute to system design reviews and risk assessments
  • Act as a technical point of contact and subject matter expert for the project and operation 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.

Requirements:

  • B.Sc. or M.Sc. degree in aerospace, mechanical, process/energy/chemical 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
  • 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)

Nice to have:

  • Modeling and simulation of fluid systems by means of software such as EcosimPro, Python/Matlab script, and/or CFD
  • Hands-on experience with fluid systems, e.g., assembly of piping systems, participating in commissioning or testing operations, etc.
What we offer:
  • Employee Participation Program: Share in our success through our virtual company share program
  • 30 days of vacation
  • Company pension plan: Secure your future with our company pension plan, featuring a 20% employer contribution after the probation period
  • Subsidised lunch: Stay energised with delicious, subsidised lunches every day
  • Public transport ticket: Commute with ease using a fully financed Deutschlandticket
  • Sport Clubs membership: Stay fit with our sponsored sports club memberships (EGYM Wellpass)
  • Individual learning allowance: Grow your skills with an individual learning budget granted after the probation period
  • Childcare allowance: Receive a childcare allowance for your non-school-age children
