Lead Propulsion Engineer, Mechanical 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.

Not a traditional engineering

job
As the Lead Propulsion Engineer, Mechanical Design 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 turbomachinery 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 ac

tion.
You won't be a cog in a machine. You'll be a highly visible operator trusted to define how we engineer turbomachinery structures, as well as actually create and deliver historically important products like the Symphony turbofan engine that will power the Overture supersonic air

liner.

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 fin

d their calling.
This job is demand

ing and rewarding
At some companies, you can choose to work long, smart, or hard. At Boom, you'll b

e doing all three.
You'll move with urgency. You'll manage ambiguity. You'll operate at a high standard. And your work will be visible to company leadership, including the founder. If you want a comfortable engineering role where you run processes and rely on executing procedures defined long a

go, look elsewhere.
If you want to be part of a team that could be remembered a century fro

m now, keep reading.The primary reward of this role is the work itself: partnering with extraordinary people to design and build breakthrough machines. You'll also be well compensated, with competitive cash compensation and meaningful equity grants with significant upside. This is a chance to build more than a product. It's a chance to build a company that hi

Why Boom
Boom 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.
In return, you'll get real ownership, the chance to work with exceptional teammates, and the opportunity to help build a product line capable of powering the future of supersonic flight and next-gen

eration energy systems.
