Propulsion Engineer, Turbine Systems Aerodynamics and 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 Boom At 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 turbine team is at the heart of it. As a Turbine Design Engineer, you’ll work shoulder to shoulder with aircraft designers, systems leads, and test engineers to architect the hot section of Symphony—from concept through certification. You’ll design, optimize, and build high-performance turbine 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 in. Role Overview As part of the Propulsion Team, you will: Lead the development of the Symphony turbine system (High pressure and Low pressure), including performance and aerodynamic design Design airfoils and and flowpath via CFD analysis Develop 1D meanline models, design blading for airfoils, develop performance maps, spec out and participate in rig tests, assess as-built hardware, and influence how these things affect the overall Overture aircraft and Symphony integrated propulsion system Advocate for component rigs when deemed necessary, analyze rig and engine test data, recommend courses of action Develop and integrate toolchains and processes, including multi-disciplinary workflows and automation that fully integrate engine and propulsion analyses with airframe development Coordinate with leadership, team members, and suppliers to ensure the designs can support the manufacturing metrics Beyond 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 Candidate Bachelor’s or Master’s in Mechanical or Aerospace Engineering or related field Self-motivated individual with strong interpersonal skills who can be a team player and solve challenging problems Design experience in axial turbomachinery leading various different phases of the design process using different fidelity of the tools such as meanline, 2D analyses, and 3D analyses (e.g., geometry creation, mesh, and execute CFD) Proficiency in CAD to support the module integration efforts in the engine Proficiency in Python or similar programming languages Experience working with engine cycle analysis tools such as NPSS or PyCycle Willingness 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 forward What Will Set You Apart Component or module ownership experience in a turbomachinery program or product Supersonic jet engine design experience Part 33 commercial certification experience Experience in life assessments of turbine systems driven by thermal and structure failures Experience analyzing secondary flow systems inside engines Background in developing design tools, methods, and processes Testing and data-reduction experience Experience with Axstream or ADS turbomachinery software A strong desire
