About the role

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. We're a team of passionate engineers dedicated to advancing aerospace. We're generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy.

Responsibilities

  • Architect high-performance, high-speed geartrain systems with consideration for high-speed rotordynamic effects, lubrication, and highly integrated interfaces
  • Perform gear design calculations (AGMA/ISO standards), including load capacity, contact stress, and bending fatigue
  • Conduct dynamic analysis of rotating systems including vibration, critical speed, and noise, vibration, harshness (KissSoft, Simcenter, SMT MASTA, Ansys)
  • Design and analyze custom shaft, bearing, housing, and lubrication system hardware and establish subsystem testing to validate component performance
  • Specify qualification testing and analyze test data for hardware behavior and performance characterization
  • 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

Requirements

  • 5+ years hands-on experience with transmission design and/or test in automotive, aerospace, or power generation applications
  • Foundational knowledge of rotordynamics, fatigue effects, lubrication systems, and transmission failure modes
  • Familiarity with test instrumentation, data reduction, and anchoring analysis with experimental results
  • Takes initiative for continuous improvement (not just completing assigned tasks)
  • Flexibility to work in a fast-paced and high-growth environment
  • Attentive to detail and maintain a high level of quality in all work
