Build Engineer (Sign On Eligible)

About the role

A jet engine is a few thousand parts surviving temperatures above the melting point of the metals they're made from, at rotational speeds that push the limits of material science, for thousands of hours. Most engines take a decade and a billion dollars to develop. We are building ours differently.

At Boom we are developing Symphony — the engine that will power Overture, the world's fastest airliner and Superpower, the natural gas turbine and revenue engine that fuels our endeavors while unblocking next-gen AI data centers. We are building it in Denver, at a pace and cost point the industry says is impossible, because the industry has forgotten what's possible.

We are hiring Build Engineers to own modules of the engine end-to-end: concept, design, drawings, supplier interface, first article, assembly, and test integration. You will not hand a drawing to "manufacturing." You are manufacturing — and design, and supply chain, and the test stand tech you brought a coffee to this morning. You will delete parts. You will simplify interfaces. You will put your hands on hardware. And when your module fires on the test stand, it will fire because you made it fire.

What you'll do

• Own a module of the Superpower engine — turbomachinery, mechanical systems, or structures/integration — from requirements through test.
• Drive design decisions that minimize part count, simplify assembly, and shorten the path from drawing to hardware.
• Live at the interface between design and fabrication: work directly with our in-house shop and external suppliers to get parts made right, fast, and on budget.

• Integrate your hardware onto test stands.
• Watch it run.
• Break it.
• Fix it.
• Ship the next rev.

• Raise the bar on everyone around you.
• You probably have
• A degree in Mechanical, Aerospace, or Manufacturing Engineering — or equivalent hands-on experience. The degree field is less important than manufacturing exposure; we hire build engineers with robotics, and biomedical backgrounds.
• Real DFM/DFA intuition — you can look at a part and see how it will be made.
• Hands-on experience turning a design into actual hardware, preferably in a high-consequence environment (aerospace, automotive at scale, defense, energy, race cars, robotics).
• A track record of making things simpler, cheaper, and faster to build.
• You will thrive here if
• You believe the shop floor is the most interesting room in the building.
• You are equally comfortable talking to the machinist making your part as the CFD or FEA analyst who set the requirements — and you understand the "why" on both ends.
• You have strong opinions, held loosely, and you'd rather change your mind today than defend a bad idea for six months.

We are not the right place for engineers who want to own a requirements document, ship CAD over the wall, and let someone else figure out how to build it. We are exactly the right place for engineers who want to go home at night knowing their part exists because of them.
