Mechanical Engineer (Early Career, Exceptional Talent)

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. We hire a small number of early-career engineers and give them a level of ownership that most companies reserve for people with a decade of experience. You won't be supporting someone else's design or waiting your turn. You'll be the engineer of record on systems that matter, making real decisions, and seeing your work turn into hardware. We're building two engines at once: Superpower, a 42 MW gas turbine for AI data centers, and Symphony, a medium-bypass turbofan designed for Mach 1.7 cruise.

Responsibilities

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; Plan and support assembly processes, working closely with manufacturing engineers on the floor to make sure your designs can be built, assembled, and serviced; Design and run component and system-level tests — instrument the hardware, collect data, interpret results, and use what you learn to make better engineering decisions faster; Collaborate across propulsion, electrical, and manufacturing teams to make sure your subsystems integrate cleanly with the rest of the engine

Requirements

A degree in Mechanical Engineering, Aerospace Engineering, or equivalent hands-on hardware experience; At least one internship or co-op where you designed, analyzed, or built real-world mechanical systems; Hands-on CAD and analysis experience – proficiency with standard 3D CAD modeling (e.g., NX, SolidWorks, CATIA) and structural/thermal FEA tools; A rock-solid grasp of core mechanical engineering fundamentals – statics, dynamics, mechanics of materials, machine design, and fluid mechanics/thermodynamics; A track record of finishing hard things, inside school and outside of it; Applicant must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State

Benefits

Medical coverage, with Boom paying 70% of medical premiums; Fully paid dental and vision premiums for employee-only coverage; A $100–$300 company HSA match on eligible medical plans; A 401(k) with a company match; Generous paid time off and company holidays; Paid parental leave; Confidential counseling, coaching, and therapy resources for you and your family; Company-paid life and disability insurance; Pet insurance; A $1,000 contribution to Invest America accounts for Boom babies; Healthy meals, an on-site gym, and a fully stocked kitchen; Ongoing wellness events; Discounts on technology, concerts, and rental cars; A dedicated real estate team to help you find a home; competitive pay; meaningful equity
