Senior Propulsion Engineer - Engine Mechanical Design

Boom Supersonic's mission is to make the world dramatically more accessible through a renaissance in supersonic flight. Boom is developing the Symphony supersonic engine, which powers the Overture supersonic airliner and the Superpower natural gas turbine for AI. Overture will fly at twice the speed of today's subsonic jets over water and 50% faster over land with Boomless Cruise.Start the Best Work of Your Career at BoomAt Boom, our remarkably small team built the groundbreaking XB-1 supersonic jet and designed the world's fastest airliner Overture. What made it possible? Exceptional people-driven, curious, and committed to building what's never been built before.Now, we're applying that same approach to Symphony-the first jet engine purpose-built for sustainable supersonic flight. It will be the fastest development of a large-scale propulsion system in aviation history, and our engine mechanical design team is at the heart of it.As a Mechanical Design Engineer, you'll work shoulder to shoulder with aircraft designers, systems leads, and test engineers to architect the mechanical systems of Symphony-from concept through certification. You'll design, optimize, and build the engine mechanical systems that make supersonic travel possible. And you'll be there when it all comes together-when the Symphony prototype roars to life on the test stand this year, and takes flight just a few years from now.If you're the kind of engineer who chases understanding, thrives in the unknown, and gets energy from building what's never been built-you'll fit right inRole OverviewAs part of the Propulsion Team, you will:Own the design features covering all the mechanically dynamic phenomena in the engine, including loads, actuation, rotordynamics, failure scenarios, and moreDevelop technically sound design solutions to get symphony turbofan in the air as fast as possible!Interpret, define and review tolerances and features on part drawingsCreate physical layouts, models, and general arrangements of modules and whole engines such as 2D cross sections, 3D models, tolerance stackups, etc.Contribute to the creation of whole engine models that incorporate structures, rotors, ducts, services routing, actuation, secondary air systems and thermal managementCollaborate on specifications and design requirements for each module and help lead cross discipline integration effortsAct as the technical owner for all mechanical aspects of the engine, including fits, seals, mounts, joints and other componentsDevelop and implement plans for assembly and disassembly for both development and productionBeyond these specific things, there are many opportunities to get involved in all aspects of Symphony engine development and Overture propulsion system integration, including fabrication and testing. Bring your curiosity!Ideal CandidateBachelor's or Master's in Mechanical or Aerospace Engineering or related fieldExpert-level experience with CAD systems such as 3DX, Catia or NXExpertise in Geometrics Dimensioning and Tolerancing (GD&T)Familiarity with a variety of manufacturing techniques used in gas turbine production (single crystal casting, hollow core fan blades, linear friction welding, additive manufacturing, etc.)Leadership experience in designing turbomachinery modules and parts, as well as throughout different phases of a programAbility to clearly think through and communicate coupled engine and aircraft system level interactionsWillingness to both speak and listen, to give opinions and receive opinions, to consider all the data and be part of building the team consensus to move forwardWhat Will Set You ApartRig testing or engine testing experienceSupersonic jet engine design experiencePart 33 commercial certification experienceExperience with parametric modeling and PLM/PDMKnowledge of heat transfer and structural analysesExperience in the part disposition processBackground in developing design tools, methods or processesProficiency with Python or similar programming languagesA strong desire to avoid bureaucracy and move fast in a dynamic environmentWe're hiring at multiple levels of experience-whether you're early in your career or bring decades of design expertise, we'd love to hear from you.CompensationP3 Level - Typically 5 - 10 years of experience - Base salary range: $107,000 - $135,000P4 Level - Typically 10 - 15 years of experience - Base salary range: $133,000 - $169,000P5 Level - Typically 15 + years of experience - Base salary range: $160,000 - $203,000Actual compensation will vary based on factors including, but not limited to, location, experience, and performance.
