Propulsion Engineer, Engine Cooling & Air Systems

Overview

Boom Supersonic’s mission is to make the world dramatically more accessible through a renaissance in supersonic flight. We are developing the Symphony supersonic engine, which powers the Overture supersonic airliner and the Superpower natural‑gas turbine for AI. Overture will fly at twice the speed of today’s subsonic jets over water and 50% faster over land with Boomless Cruise.

• Take ownership of the Secondary Air Systems (SAS) engineering for the Superpower gas turbine engine.
• Be responsible for the engine thermal‑management systems for secondary flows.
• Provide inputs to a whole‑engine model, evaluate results, and recommend improvements.
• Take a big‑picture view of Superpower as a total system and help integrate the needs of multiple disciplines such as aero, thermal, structure, and durability.
• Develop and integrate tool chains and processes, including multi‑disciplinary workflows and automation that fully integrate engine and propulsion analyses with airframe development.
• Opportunities to get involved in all aspects of the Superpower engine development, including fabrication and testing.

• Bachelor’s or Master’s in Mechanical, Aerospace Engineering, or related field.
• Proficiency in Python or similar programming languages.
• Drive to develop expertise in engine secondary air systems engineering on a turbofan architecture.
• Ability to navigate CAD to support module integration efforts in the engine.
• Background in developing design tools, methods or processes.
• Testing and data‑reduction experience.
• Willingness to speak and listen, give opinions and receive opinions, and consider all data to build team consensus.

• Component or module ownership experience in a turbo machinery program or product.
• Experience in whole‑engine model creation and execution.
• Experience correlating engine test data to calibrate heat‑transfer models for whole‑engine modeling.
• In‑depth knowledge of different seal configurations applicable to modern turbofan or gas‑turbine engine architectures.
• Experience with secondary air systems architecture and past development programs for in‑service turbo machinery.
• Prior experience working with engine cycle analysis tools such as NPSS or PyCycle.
• Supersonic jet engine design experience.
• Part 33 commercial certification experience.
• Ability to dive deep into component‑level design and analysis.
• Experience with Axstream or ADS turbo machinery software.
• A strong desire to avoid bureaucracy and move fast in a dynamic environment.

• P2 Level (0‑5 years experience):
  Base salary range $85,000 – $105,000.
• P3 Level (5‑10 years experience):
  Base salary range $105,000 – $130,000.
• P4 Level (10‑15 years experience):
  Base salary range $130,000 – $170,000.

Actual compensation varies by location, experience, and performance. The listed range is one component of Boom’s total rewards package, which may also include long‑term incentives/equity, flexible PTO, and a suite of benefits.
