Job Description

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 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.

WHO YOU ARE:

You are a Senior Propulsion Engineer experienced in designing the combustion devices within propulsion systems. You come from a background working in ground power, aviation, automotive, or rocketry. You approach your work from a robust set of first principles which enable you to work methodically through challenging technical problems with feedback from test verification.

WHAT YOU’LL DO:

  • Lead conceptual trades for novel combustors while considering system-level impacts

  • Complete detailed designs with supporting structural, thermal, and fluid analyses

  • Implement advanced materials and manufacturing techniques to achieve performance and reliability at scale

  • Assemble prototypes firsthand, design complementary tooling, and establish work instructions

  • Conduct hardware test and analyze data to verify requirements and performance metrics

  • Understand empirical trends and iterate quickly through component-level and integrated testing

  • Diagnose hardware problems efficiently and determine corrective actions

WHAT WE’RE LOOKING FOR:

  • 5+ years hands-on experience designing combustion devices for use in propulsion or similarly complex environments

  • Expertise in design and analysis of airbreathing combustors, igniters, and fuel systems

  • Proficient in CAD solid body and surface modeling (Siemens NX), engineering drawings, and GD&T

  • Strong understanding of thermodynamics, heat transfer, and fluid behavior

  • Hands-on prototype assembly and test stand experience

  • Experience with data acquisition and instrumentation selection for analyzing stability and performance in elevated temperate environments

  • Understanding and familiarity with high-temperature materials, coatings, and joining methods relevant to combustion

  • Experience with root-cause analysis of hardware failures

  • Takes initiative for continuous improvement (not just completing assigned tasks)

  • Flexibility to work in fast-paced 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)

  • 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
