Start the Best Work of Your Career  Boom, we’re building the world’s fastest airliner—driven by a team that embraces speed, owns every challenge, and never stops learning. Our propulsion team is pioneering Symphony, a custom engine designed from the ground up for sustainable supersonic flight. To make it real, we need mechanical engineers who thrive on hands‑on problem solving—designing, building, and testing the systems that make engine development possible.

• Design and develop engine subsystems and accessories (gearboxes, oil, fuel, or starter systems).
• Design and build structural and mechanical elements of the engine test stand and mounting system.
• Own your systems end‑to‑end: concept to design, analysis, build, and test.
• Act as control room operator during ground engine tests, monitoring your systems in real time.
• Build models, assemblies, and detailed drawings in CAD to support manufacturing and assembly.
• Create and execute test plans—including instrumentation, data review, and test iteration.
• Collaborate closely with design, manufacturing, and test teams to deliver fully integrated systems.
• Communicate findings and plans clearly across a multidisciplinary team.

• Mechanical or Aerospace Engineering degree (or equivalent experience).
• Strong grasp of engineering fundamentals, especially mechanical, fluid, and thermal systems.
• Proficient in CAD for design and drawing generation.
• Demonstrated experience with test planning, data analysis, and hands‑on testing.
• Clear, confident communicator who thrives in fast‑paced, cross‑functional environments.
• Meticulous attention to detail and system‑level thinking.
• Deep sense of ownership—you’re driven to understand how things work, and make them better.

• Experience with full product or test system lifecycle—from whiteboard to test data.
• Background in aerospace fluid systems, mechanical systems or testing.
• Operational mindset—you’re comfortable with fast turns, ambiguity, and real‑time problem solving.
• Passion for sustainable aviation and the future of high‑speed flight.

• P3 Level – Base salary range: $107,000 – $135,000.
• P4 Level – Base salary range: $133,000 – $169,000.
