Lead Propulsion Engineer, Structures

About this position

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.

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.

Boom Supersonic is building one of the most ambitious industrial programs of this century. The work is hard, the pace is fast, and the expectations are high.

As the Lead Propulsion Engineer, Structures at Boom, you won’t be executing prescribed engineering tasks within a rigid framework set in stone decades ago.

You’ll be part of a small, high‑performance turbo machinery 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 highly visible operator trusted to define how we engineer turbo machinery structures, as well as actually create and deliver historically important products like the Symphony turbofan engine that will power the Overture supersonic airliner.

• Lead the structural and stress engineering domains for the Symphony turbofan engine, including static and rotating components
• Take ownership of the structural metrics by routinely executing structural & life assessments using applicable analytical methods and analyses (FEA)
• Develop and integrate tool chains and processes, including multi‑disciplinary workflows and automation
• Beyond these specific things, there are many opportunities to get involved in all aspects of Symphony engine development and Overture propulsion system integration, including fabrication and testing. Bring your curiosity!

• Bachelor’s or Master’s in Mechanical or Aerospace Engineering or related field
• 15+ years of professional experience
• Proficiency in Python or similar programming languages
• Experience in structural assessments in rotating and non‑rotating components for the axial turbo machinery applications (Goodman diagram, Campbell diagram, etc.)
• Analytical and experimental experiences with analyzing different fatigue phenomena, such as flutter, HCF, LCF, thermo‑mechanical fatigue, etc.
• Expertise in various analytical tools and methods such as ANSYS Mechanical / NASTRAN
• Collaborate with aero, thermal, SAS to find the right structural solutions that meet all loads and failure mode cases
• Ability to navigate through CAD to support module integration efforts in the engine
• Willingness to both speak and listen, to give opinions and receive opinions, to consider all the data and be part of building the team consensus to move forward

• Component or module ownership experience in a turbo machinery program or product
• Experience with engine rig tests, bearings, or rotor dynamics
• Knowledge of engine mounts and dynamic load scenarios such as fan blade failure and sustained imbalance under wind‑milling
• Experience working with advanced materials such as superalloys
• Experience simulating impact dynamics in tools such as LS‑DYNA
• Experience with developing tools that incorporate structures analysis into multi‑disciplinary analysis and design workflows (MDAO)
• 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

• P5 Level - Typically 15 + years of experience - Base salary range: $160,000…
