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

Boom Supersonic is building the breakthrough Overture supersonic airliner and the Superpower natural gas turbine — machines that push the boundaries of physics, manufacturing, and industrial ambition.

But aircraft and engines don't build themselves. The single most important variable in our success is a world-class team — people who are unusually talented, unusually driven, and willing to do what others won't even attempt.

That's where you come in.

As a Compressor Design Engineer, you’ll work shoulder to shoulder with aircraft designers, systems leads, and test engineers to architect the front end of Symphony—from concept through certification. You’ll design, optimize, and build high-performance fan and compression 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 compression system and take ownership of at least one area: High Pressure Compressor, Low Pressure Compressor or Fan
Design airfoils 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
Contribute to developing and integrating toolchains and processes, including multi-disciplinary workflows and automation that fully integrate engine and propulsion analyses with airframe development
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
Proficiency in Python or similar programming languages
Design experience in axial turbomachinery (including meanline and 3D steady and unsteady CFD)
Ability to navigate through CAD to support module integration efforts in the engine
Experience with high speed compressor airfoil design and tuning
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
Aerodynamics or Structures lead on the development of high speed and highly loaded turbomachinery
Airfoil tuning and aero-mechanics related analysis such as unsteady mutli-blade row CFD, flutter analysis
Experience with operability analysis and assessment at the engine level
Experience analyzing secondary flow systems inside engines
Background in developing design tools, methods or processes
Testing and data-reduction experience
Experience with Axstream or ADS turbomachinery software
A strong desire to avoid bureaucracy and move fast in a dynamic environment

We’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.
