Turbomachinery Engineer (Early Career, Exceptional Talent)

Boom Supersonic is hiring a small number of early-career Turbomachinery Engineers who will own a piece of the machine, such as a combustor liner, compressor stage match, secondary air system, or transient stability or fuel-air mixing problem, and be accountable for making it work on the test stand. The team is building two engines: Superpower, a 42 MW gas turbine for AI data centers, and Symphony, a medium-bypass turbofan designed for Mach 1.7 cruise.

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 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 extreme aerothermal loads and production manufacturability

Requirements

Degree in Aerospace Engineering, Mechanical Engineering, or equivalent hands-on propulsion/thermal-fluids experience; At least one internship, co-op, or equivalent experience analyzing, designing, or testing real-world propulsion, fluid, or thermal systems; Hands-on modeling and analytical experience with 1D/3D CFD tools (e.g., Ansys Fluent, STAR-CCM+, OpenFOAM), thermodynamics/cycle analysis tools (e.g., NPSS, GasTurb, pyCycle), and/or FEA tools (e.g., Abaqus, Ansys Mechanical, Nastran, CalculiX); 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; Must be a U.S. citizen, lawful permanent resident, protected individual under 8 U.S.C 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State to conform to ITAR and EAR requirements

Nice to have

Designed rocket injectors; Led a competition team (e.g., Formula SAE, AIAA Design/Build/Fly) where you owned propulsion, aerothermal, or fluid networks; Propulsion work in an internship that most engineers don't see for years; Interest in GPU-accelerated CFD, turbine blade flow bench, and engine test stands

Benefits

Competitive pay and meaningful equity; Medical coverage with Boom paying 70% of medical premiums; Fully paid dental and vision premiums for employee-only coverage; $100–$300 company HSA match on eligible medical plans; 401(k) with company match; Generous paid time off and company holidays; Paid parental leave; Confidential counseling, coaching, and therapy resources; Company-paid life and disability insurance; Pet insurance; $1,000 contribution to Invest America accounts for Boom babies; Healthy meals, on-site gym, and fully stocked kitchen; Ongoing wellness events; Discounts on technology, concerts, and rental cars; Dedicated real estate team to help find a home
