POSTED ON 1/7/2026
AVAILABLE BEFORE 2/5/2026
ABOUT US:

Astro Mechanica is a vertically integrated aerospace company building a faster, more connected future. Our mission is to democratize high-speed flight by making supersonic travel flexible, accessible, and sustainable. We believe that rapid, on-demand, point-to-point global mobility will become the new standard for moving people and goods across the planet. To achieve this, we are integrating our advanced airframe and engine technologies—which include Duality™, our proprietary dual-use propulsion system—with a new flight operations model to make supersonic transport as efficient and economical as commercial air travel is today. In the near term, we are developing adaptable, high-speed systems to close aircraft performance gaps for the United States government.

WHO WE ARE:

We're a team of hardcore engineers who live and breathe aerospace. We’re generalists who each have subject matter expertise and operate in a flat organizational structure. We move fast and build world-changing technology in a pragmatic and competent workplace culture.

Who You Are

Astro Mechanica is looking for a Senior Fluid Systems Engineer to join our growing team. The ideal candidate is someone who has a deep-seated understanding of complex system dynamics, and can take full ownership of modeling the thermal/fluid network of a novel engine architecture. Your work at Astro Mechanica will have a direct impact on the configuration and performance of the turboelectric adaptive jet engine.

In this role, your mission will be to architect, analyze, build, and test critical fluid systems for the propulsion systems. You will collaborate between propulsion, aircraft, and test teams to deliver optimized fluid hardware for the flight vehicle, proven through rigorous ground testing. You are attentive to detail and enjoy solving nuanced, interconnected problems.

What You’ll Do

  • Architect fluid system networks supporting the propulsive engine fuel supply and thermal management
  • Predict behavior through detailed analysis (Amesim, Thermal Desktop, EES, REFPROP)
  • Design custom hardware and establish subsystem testing to validate component performance
  • Mechanical layout of fluid systems while considering design for manufacturing, installation, and maintenance
  • Analyze test data for characterization hardware behavior and performance
  • Improve and maintain the accuracy of simulation models through anchoring to historical and internally generated test data
  • Define instrumentation placement with understanding of measurement limitations
  • Diagnose hardware/software problems efficiently and perform corrective actions

WHAT WE’RE LOOKING FOR:

  • 5 years hands-on experience with fluidic and propulsion systems, test operations
  • Foundational knowledge of fluid dynamics, thermodynamics, and compressible flow
  • Understanding of fluid systems and instrumentation hardware (pressure, temperature, flow meters, pumps, heat exchangers, valves, regulators, pneumatics)
  • Familiarity with test instrumentation, data reduction, and anchoring analysis with experimental results
  • Experience with P&ID’s, 0D/1D thermal/fluid networks for gases and liquids
  • Takes initiative for continuous improvement (not just completing assigned tasks)
  • Flexibility to work in fast-paced and high-growth environment
  • Attentive to detail and maintain a high level of quality in all work

Perks & Benefits

  • Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
