Propulsion Engineer - Engine Cooling & Air Systems

Boom Supersonic

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

About this role

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. As a Propulsion Engineer on Engine Cooling & Air Systems, you will join the Secondary Air Systems (SAS) team as a thermal-fluids analyst.

This is not a traditional engineering job. You won't be executing prescribed analysis tasks within a rigid framework set in stone decades ago. Instead, you will bring your craft in heat transfer, internal aerodynamics, compressible flow, mechanical design, or structural analysis — and grow into the SAS discipline itself under senior engineers who will mentor you.

Secondary Air Systems is one of the highest-leverage disciplines in a modern engine — it touches cooling, sealing, thrust loads, bearing life, and hot-section durability. You will be part of a small, high-performance propulsion engineering team responsible for building one of the most ambitious hardware companies of this century.

You will be part of inventing a new 21st century engine manufacturer from the ground up, one that is built on modern tooling and a bias toward action. You won't be a cog in a machine — you'll be a trusted contributor doing real analysis work on a real engine, the Symphony turbofan that will power the Overture supersonic airliner.

Requirements

Strong adjacent expertise in thermal analysis, internal aerodynamics, compressible flow, mechanical or structural design, or analysis tool creation
Intense curiosity and learning aptitude
Willingness to absorb the Secondary Air Systems discipline from senior engineers
Experience as a thermal-fluids analyst in a relevant engineering field
Ability to evaluate whole engine model results and recommend improvements
Capability to integrate multiple engineering disciplines including aero, thermal, structure, and durability

Responsibilities

Take ownership of the Secondary Air Systems engineering for the Superpower gas turbine engine
Be responsible for the engine thermal management systems for secondary flows
Provide inputs to a whole engine model, evaluate results, and recommend improvements
Take on the big picture view of Superpower as a total system and integrate the needs of multiple disciplines such as aero, thermal, structure, and durability
Perform thermal-fluids analysis including heat transfer, internal aerodynamics, and compressible flow
Contribute to cooling, sealing, thrust load, and hot-section durability analysis
Collaborate with senior engineers to absorb the SAS discipline and grow into deeper ownership

Benefits

Mentorship from senior engineers who will teach you the SAS discipline
Opportunity to work on a real engine — the Symphony turbofan powering the Overture supersonic airliner
Be part of inventing a new 21st century engine manufacturer from the ground up
Work in a small, high-performance propulsion engineering team with a bias toward action
