Boom Supersonic

Centennial, US · Full-time · $85,000 – $170,000

About this role

Boom Supersonic's mission is to make the world dramatically more accessible through supersonic flight. They are developing the Symphony supersonic engine for the Overture airliner. As a Combustion Systems Engineer, you will work on real combustion CFD for a real engine.

You won't execute prescribed CFD tasks within a rigid framework. Instead, you'll join a small, high-performance propulsion team building one of the most ambitious hardware companies of this century. You'll do real combustion CFD on the Symphony turbofan.

You won't be a cog in a machine. You'll be a trusted contributor surrounded by senior engineers who will mentor your growth into deeper ownership. The single most important variable in our success is a world-class team.

You'll be part of inventing a new 21st century engine manufacturer from the ground up, built on modern tooling and a bias toward action. This is not a traditional engineering job; you will help build the Symphony engine that pushes the boundaries of physics, manufacturing, and industrial ambition.

Requirements

Demonstrable combustor architecture knowledge — fuel injection, mixing, primary/secondary/dilution zones, liner design, exit profile control.
Strength in combustion CFD and high-fidelity methods for flow prediction and combustion dynamics — RANS, LES, CHT, chemistry coupling.
Experience with emissions modeling.
Strong skills in rig design, test execution, and data reduction.
Experience in multi-disciplinary integration — compressor exit, turbine inlet, SAS, mechanical design, materials.
Work experience in cycle-level impact — combustor influence on SFC, T4 capability, hot section life.
Component or module ownership experience in a turbomachinery program or product.
A strong desire to avoid bureaucracy and move fast in a dynamic environment.

Responsibilities

Design combustor architecture including fuel injection, mixing, primary/secondary/dilution zones, liner design, and exit profile control.
Perform combustion CFD using high-fidelity methods such as RANS, LES, CHT, and chemistry coupling.
Conduct emissions modeling to evaluate and optimize combustor performance.
Design rigs, execute tests, and perform data reduction to validate designs.
Integrate combustion system with compressor exit, turbine inlet, secondary air system, mechanical design, and materials.
Assess cycle-level impact of combustor on specific fuel consumption, T4 capability, and hot section life.
