Turbomachinery Engineer (Early Career, Exceptional Talent)

About the role

At Boom, you'll own complex propulsion challenges from day one—such as stall margin on a high-pressure-ratio compressor or cooling a turbine blade running in a gas path above its own melting point. We hire a small number of early-career engineers and give them more responsibility than their résumés justify. Unlike most companies, where you'd spend years meshing geometry or re-running cycle decks before touching real hardware, here you’ll own a piece of the machine: a combustor liner, compressor stage match, secondary air system, or an unsolved transient stability or fuel-air mixing problem. You’ll be accountable for making it work on the test stand.

We're building two engines simultaneously: Superpower, a 42 MW gas turbine for AI data centers, and Symphony, a medium-bypass turbofan designed for Mach 1.7 cruise. The problems we're solving don’t have playbooks—you will help write them. This role is demanding, rewarding, and not for everyone.

You're the right person if

• You've done something extraordinary early—designed rocket injectors, led a competition team (e.g., Formula SAE, AIAA Design/Build/Fly) where you owned propulsion, aerothermal, or fluid networks, or completed propulsion work in an internship that most engineers don’t see for years.
• You love building and want to work long, smart, and hard to create things with real impact.
• You want ownership, not a lane, on a team of high performers.
• You get more energized when a problem gets harder, not less.
• You're uncomfortable waiting for someone else to find the answer.
• GPU-accelerated CFD, the turbine blade flow bench, and engine test stands excite you more than a conference room.

Responsibilities

• Own a defined piece of the propulsion system—from 1D cycle performance and 3D CFD modeling to fuel nozzle design, secondary air systems, rotordynamics, or variable guide vane geometry—with real accountability for the outcome.
• Work directly on the test stand and in the shop with mechanical, materials, and controls teams to turn propulsion concepts into operational gas turbine hardware.
• Analyze thermodynamic cycles, internal flow networks, and turbomachinery physics to set the operating limits for machines that go into service within the year.
• Support engine testing operations in real time—evaluating raw data against expected performance models, troubleshooting anomalies, and driving hardware design revisions.
• Partner with design and manufacturing engineers to ensure gas-path components are optimized for both extreme aerothermal loads and production manufacturability.

Requirements

• A degree in Aerospace Engineering, Mechanical Engineering, or equivalent hands-on propulsion/thermal-fluids experience.
• At least one internship, co-op, or equivalent experience where you analyzed, designed, or tested real-world propulsion, fluid, or thermal systems.
• Hands-on modeling and analytical experience—proficiency with 1D/3D CFD tools (e.g., Ansys Fluent, STAR-CCM+, or OpenFOAM), thermodynamics/cycle analysis tools (e.g., NPSS, GasTurb, or pyCycle), and/or finite element analysis (FEA) tools (e.g., Abaqus, Ansys Mechanical, Nastran, or CalculiX).
• A rock-solid grasp of core propulsion fundamentals—thermodynamics, compressible fluid mechanics, heat transfer, and combustion.
• A track record of finishing hard things, inside school and outside of it.

Work Location

This position requires 100% onsite work at Boom's headquarters: 6803 S Tucson Way, Centennial, CO 80112.

Pay
