Senior Turbomachinery Engineer

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 Engineer, Turbomachinery to own the design of our propulsion system’s compressor section. You are a seasoned engineer with deep roots in turbomachinery and have demonstrated excellence in aerospace and/or ground based systems. While we desire a track record in compressor aerodynamics we highly value professional experience in radial compressors, inducers, impellers and gas driven turbines, especially those that have been on systems that reached orbit. Blade design, flowpath coupling, rotordynamics, drive shafts, dynamic seals and bearings are all topics you discuss with confidence gained from experience. Analysis, design, testing, and optimization for high-performance engines is what you are looking for in your next role, and you thrive at the intersection of fluid dynamics, thermodynamics, and real-world integration challenges. You can lead from concept through to test and iteration. You’re a builder, an analyst, and a mentor—equally comfortable diving into CFD models or rolling up your sleeves in a test cell. Your contributions will directly influence the efficiency and thrust capability of the world’s first turboelectric adaptive jet engine.

WHAT YOU’LL DO:

• Own the aerodynamic and mechanical design of axial compressor stages from clean-sheet to flight-ready hardware

• Run compressor design trade studies across a wide operating envelope, balancing performance, operability, and structural integrity

• Validate compressor design through test campaign execution, selection, and placement of instrumentation for performance calculations and spectral analysis

• Analyze test data and integrate findings into system-level performance models and next-gen hardware design cycles

• Develop, validate, and iterate computational models using StarCCM+, AxSTREAM, and other in-house tools

• Utilize propulsion cycle models (GasTurb, NPSS) to predict engine performance from compressor maps

• Evaluate turbomachinery designs using FEA and rotordynamics tools (e.g., DyRoBes) to analyze critical speeds, balance conditions, and Campbell diagrams

• Lead bearing selection, preload definition, and stiffness trade studies in coordination with thermal management constraints

• Define GD&T for compressor assemblies, including tolerance stackup, fitment, and non-contacting seal clearances

• Specify manufacturing methods for high-performance, precision turbomachinery components, enabling rapid iteration with cost-effective processes

• Influence the broader propulsion and aircraft system architecture with innovative compressor design solutions

WHAT WE’RE LOOKING FOR:

• 5+ years of experience in turbomachinery analysis/design, with a focus on high mass flowrate compressors and advanced fan systems preferred

• Proven track record of blade geometry development using CFD, streamline curvature, and 1D meanline methods

• Familiarity with test instrumentation, data reduction, and anchoring analysis with experimental results

• Deep understanding of propulsion system integration, thermodynamics, rotordynamics, and turbomachinery

• Demonstrated history of innovation, technical authorship, and real-world test experience

• Proficient in solid and surface CAD modeling (Siemens NX) and multiphysics analysis

• Experience integrating compressor design into full engine systems, with understanding of thermodynamics, rotordynamics, and cycle-performance coupling

• Skilled in engine cycle modeling tools (GasTurb, NPSS) and scripting tools (Python, Matlab) for analysis automation and data processing

• Effective communicator capable of leading cross-functional design reviews and contributing to system architecture discussions

• Flexibility to work in fast-paced environment

• Attentive to detail and maintain a high level of quality and ownership in all work

PERKS & BENEFITS:

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

• 401(k) program and transparent stock option plan

• Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time

• Flexible work environment

• Company-funded perks, including weekly team lunches and Astro Mechanica swag
