Senior Propulsion Engineer – Combustion Systems Aerodynamics and Design

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 combustor team is at the heart of it.

As a Combustion Systems Engineer, you’ll work shoulder to shoulder with aircraft designers, systems leads, and test engineers to architect the heart of Symphony—from concept through certification. You’ll design, optimize, and build high-performance combustor 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 combustion system
• Take ownership of the combustor design, analysis and test efforts
• Guide development programs through analysis, bespoke rig testing, incorporation into engine build demos and the Symphony turbofan engine
• Contribute to developing and integrating toolchains and processes
• 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!

The 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 modern combustor architectures, leading various different phases of the design process, and using tools of varying fidelity levels (1D to 3D analyses)
• Experiences working with combustor analysis tools such as Fluent, STAR-CCM+, or OpenFOAM
• Significant meshing and CFD modeling experience
• Proficiency in CAD to support module integration efforts in the engine
• Proficiency in Python or similar programming languages
• 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

• Combustor module ownership experience in a turbomachinery program or product
• Supersonic jet engine design experience
• Part 33 commercial certification experience
• Prior experience with higher fidelity CFD simulation methods such as LES and CHT
• Knowledge of chemical kinetics mechanisms and emissions modeling
• Background in developing design tools, methods or processes
• Testing and data-reduction experience relevant for the modern combustor designs
• A strong desire to avoid bureaucracy and move fast in a dynamic environment
• Demonstrates a strong work ethic and ambition, complemented by effective collaboration skills in a team setting
• Excels in a high-energy, independent, and challenging work 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.
