Senior Propulsion Engineer – Systems Performance & Operability

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 systems performance team is at the heart of it.

As a Systems Performance and Operability Engineer, you’ll work shoulder to shoulder with aircraft designers, systems leads, and test engineers to architect the way Symphony systems work—from concept through certification. You’ll design, optimize, and build the 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 Systems Performance engineering for the Symphony turbofan engine
• Perform steady state and transient engine cycle studies and modelling, operability assessment, engine test planning and execution, data analysis to support the development the Symphony turbofan
• Take on the big picture view of Symphony as a total system and be responsible for helping integrate the needs of multiple disciplines such as aero, thermal, structure, mechanical design in the engine
• Develop and integrate 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
• Significant experience as an engine performance and operability engineer working on a turbofan architecture
• Demonstrated experience in engine thermodynamic steady-state and transient performance modeling and test data analysis
• Strong analytical skills and knowledge of thermodynamics, aerodynamics and engine transient operations and operability
• Ability to clearly think and communicate through coupled engine and aircraft system level interactions
• Ability to navigate through CAD to support module integration efforts in the engine
• Prior 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
• Experience with operability audits and inlet distortion, engine transients, and component-level stack-ups
• Supersonic jet engine design experience
• Part 33 commercial certification experience 
• Ability to dive deep into component-level design and 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.
