Stall margin on a high-pressure-ratio compressor. Cooling a turbine blade running in a gas path above its own melting point. At Boom, you'll own problems like these in your first year.
We hire a small number of early-career engineers and give them more responsibility than their rsums justify. At most companies you'd spend a few years meshing geometry someone else defined and re-running cycle decks someone else scoped before you touch real hardware. Here, entry-level Turbomachinery Engineers get a piece of the machine - a combustor liner, a compressor stage match, the secondary air system that cools the turbine disks, a transient stability or fuel-air mixing problem nobody has solved yet - and are accountable for making it work on the test stand.
We're building two engines at once: Superpower, a 42 MW gas turbine for AI data centers, and Symphony, a medium-bypass turbofan designed for Mach 1.7 cruise. Neither is on a schedule that leaves room for waiting your turn. The propulsion problems we're solving don't have playbooks. You will help write them.
This job is demanding and rewarding. This job isn't 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 done 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 that have real impact.
- You want ownership, not a lane, on a team with other 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 sound more interesting to you than a conference room.
What you'll do- 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.
You Probably Have- 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.
