Propulsion Engineer, Combustion Systems Aerodynamics and Design

Boom Supersonic’s mission is to make the world dramatically more accessible through a renaissance in supersonic flight. Boom is 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. Start the Best Work of Your Career at Boom Boom Supersonic is building the breakthrough Overture supersonic airliner and the Superpower natural gas turbine — machines that push the boundaries of physics, manufacturing, and industrial ambition. But aircraft and engines don't build themselves. The single most important variable in our success is a world-class team — people who are unusually talented, unusually driven, and willing to do what others won't even attempt. That's where you come in. Not a traditional engineering job As a Combustion Systems Engineer at Boom, you won't be executing prescribed CFD tasks within a rigid framework set in stone decades ago. You'll be part of a small, high-performance propulsion engineering team responsible for building one of the most ambitious hardware companies of this century. You'll be part of inventing a new 21st century engine manufacturer from the ground up, one that is built on modern tooling and a bias toward action. You won't be a cog in a machine. You'll be a trusted contributor doing real combustion CFD work on a real engine — the Symphony turbofan that will power the Overture supersonic airliner — surrounded by senior engineers who will mentor your growth into deeper ownership. The Ideal Candidate Demonstrable combustor architecture knowledge — fuel injection, mixing, primary/secondary/dilution zones, liner design, exit profile control Strength in combustion CFD and high-fidelity methods for flow prediction and combustion dynamics — RANS, LES, CHT, chemistry coupling Experience with emissions modeling Strong skills in rig design, test execution, and data reduction Experience in multi-disciplinary integration — compressor exit, turbine inlet, SAS, mechanical design, materials Work experience in cycle-level impact — combustor influence on SFC, T4 capability, hot section life What Will Set You Apart Component or module ownership experience in a turbomachinery program or product Supersonic jet engine or gas turbine engine design experience Part 33 commercial certification experience Background in developing design tools, methods or processes Testing and data-reduction experience A strong desire to avoid bureaucracy and move fast in a dynamic environment Compensation P2 Level - Typically 0 - 5 years of experience - Base salary range: $85,000 – $105,000 P3 Level - Typically 5 - 10 years of experience - Base salary range: $105,000 – $130,000 P4 Level - Typically 10 - 15 years of experience - Base salary range: $130,000 – $170,000 Actual compensation will vary based on factors including, but not limited to, location, experience, and performance. The range listed is just one component of Boom’s total rewards package. Other elements may include long-term incentives/equity, flexible PTO, and a suite of progressive benefits designed to support our employees’ well-being and growth. There is no set deadline to apply for this job opportunity. Applications will be accepted on an ongoing basis until the search is no longer active. The mission Engineering roles at Boom are unlike anything else in aerospace or energy: designing a supersonic airliner from first principles, developing advanced propulsion systems, scaling complex hardware programs in a modern manufacturing environment, and building breakthrough industrial turbines to power the next generation of AI data centers. These aren't jobs. They are career-defining opportunities. Some may even find their calling. This job is demanding and rewarding At some companies, you can choose to work long, smart, or hard. At Boom, you'll be doing all three. You'll move with urge
