About Boom Supersonic
Fuel and lube systems. Structural hardware. Component testing. Assembly processes built from scratch. At Boom, you'll own some of the hardest mechanical engineering challenges and real hardware — on day one of your career. Backed by Bessemer, Y Combinator and South Park Commons.
About the role
Engineers who want to spend their first year doing work that actually matters should apply. Internships require 100% onsite at Boom's headquarters located at 6803 S Tucson Way, Centennial, CO 80112.
What they're looking for
- You're genuinely excited by complex mechanical systems and love following a problem from whiteboard to hardware
- You'd rather own something and figure it out than wait for a perfect set of instructions
- CAD, analysis, the machine shop, and the test cell are where you want to spend your time
- You care about doing the work well — not just finishing it
- Own parts of mechanical subsystems — fuel, lube, cooling, and other balance-of-plant systems — from initial concept through analysis, drawing release, and integration into the full engine system
- Design components and assemblies that balance performance, reliability, manufacturability, and testability, making real engineering tradeoffs on hardware that actually gets built
More about this role
This job is demanding and rewarding.
- You've already done something real — built hardware, led a competition team (Formula SAE, Baja, Rocketry, Robotics), or taken on engineering work in an internship that went well beyond what most early-career engineers get to touch.
