Mechanical Engineer

Boom Supersonic•Centennial, CO

22h•$85,000 - $107,000

About The Position

We’re building Superpower—a next-generation gas turbine designed to bring abundant, reliable energy to the AI era. And like everything we do at Boom, we’re doing it with a small team, high standards, and a bias for action. Every engine starts somewhere. Ours starts with SN0—the first Superpower prototype—and Sprint Core, our pathfinder hardware. Before we light the engine, before we collect data, before we optimize performance, we have to design it, detail it, and build it. That’s where you come in. As an early-career Mechanical Engineer, you’ll begin by turning bold designs into precise, production-ready drawings for SN0. You’ll be in the shop during Sprint Core build, learning how hardware really comes together. And once you’ve earned context and credibility, you’ll design and own components and subsystems yourself. If you want to grow from detail-oriented contributor to full system owner—fast—this is your runway.

Requirements

Bachelor’s degree in Mechanical or Aerospace Engineering
Strong command of mechanical fundamentals: statics, dynamics, fluids, thermals, and material
Proficiency in CAD for part modeling, assemblies, and drawing creation
Working knowledge of GD&T and tolerance stack-ups (or a strong desire to master them quickly)
Experience through internships, co-ops, or projects that involved building or testing real hardware
Comfort spending time in a machine shop, assembly bay, or test environment—not just behind a screen
Strong attention to detail and pride in producing clean, accurate documentation
Demonstrates a strong work ethic and ambition, complemented by effective collaboration skills in a team setting
Excels in a high-energy, independent, and challenging work environment

Nice To Haves

You’ve supported a prototype build or seen hardware go from CAD to test
You’ve worked closely with machinists or fabricators and understand what makes a drawing “shop-ready”
You ask why—not just how—and want to deeply understand how turbines, gearboxes, fuel systems, and structures actually work
You’re hungry for ownership and actively seek feedback to accelerate your growth
You want to build engines that matter—and you’re motivated by the scale and urgency of bringing Superpower to life

Responsibilities

Create detailed manufacturing drawings for SN0 engine hardware, ensuring clarity, completeness, and producibility
Translate 3D CAD models into production-ready documentation with GD&T, tolerances, and inspection requirements
Partner closely with manufacturing engineers and machinists to resolve drawing questions and drive first-pass success
Support the hands-on build of Sprint Core—participating in assembly, troubleshooting, and real-time problem solving
Incorporate redlines and build feedback into updated designs and released documentation
Assist in developing test hardware, fixtures, and structural elements for engine testing
Build strong fundamentals in engine subsystems (fuel, oil, structures, accessories) through direct exposure to design and test
Progress into ownership of components and subsystems—taking hardware from concept through design, analysis, build, and test
Communicate clearly across design, manufacturing, and test teams to ensure alignment and execution
