Boom Supersonic is building Symphony, the engine powering the Overture supersonic airliner, and adapting Superpower, an industrial gas turbine for AI data centers. The team has already designed, built, and flew XB-1, the first civil supersonic jet made in America.
You will own defined performance and operability scope for Superpower and Symphony engines, from model assumptions through test evidence. Working across compressor, turbine, secondary-air, controls, and test engineering teams, you will diagnose gaps between predictions and measured behavior, then recommend design and control changes while decisions can still be made. Your work builds Boom's in-house engine-level design capability and establishes methods that will scale across both programs.
Key responsibilities include:
- Own steady-state and transient cycle modeling and operability analysis with documented assumptions and checks
- Assess stall margin and operability across transients, start behavior, and load response with component and controls teams
- Define performance and operability test questions and instrumentation needs with the test team
- Reduce test data, reconcile measured results with predictions, and calibrate models with evidence
- Integrate compressor, turbine, combustion, and secondary-air trades into engine-level recommendations and answer customer power and heat-rate questions
- Build shared PyCycle models and tools that make recurring analyses reproducible
Requirements:
- Aerothermodynamic fundamentals and depth in engine performance or operability appropriate to your level
- Hands-on use of NPSS, PyCycle, GasTurb, or comparable engine-analysis environment through industry, research, or substantial academic projects
- Ability to explain component assumptions, maps, limits, and uncertainty behind cycle predictions
- Test, laboratory, or research exposure to instrumentation, data reduction, or model-to-data comparison
- Python or equivalent for reproducible engineering analysis with clear technical communication
Differentiators:
- Transient, starting, or sub-idle modeling experience
- Ownership of stall-margin stack-ups and design/control trades
- Free-power-turbine or industrial-gas-turbine experience alongside aero-engine work, or vice versa
- Experience building tested, documented engineering tools others maintain and use
ITAR Requirement: Applicant must be a U.S. citizen, lawful permanent resident, protected individual as defined by 8 U.S.C 1324b(a)(3), or eligible to obtain required authorizations from the U.S. Department of State.
