Propulsion Engineer, Combustion Systems Aerodynamics and Design

The Role

As a Combustion Systems Engineer at Boom, 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.

What You’ll Be Doing

• Build one of the most ambitious hardware companies of this century
• Partner with extraordinary people to design and build breakthrough machines
• Manage ambiguity and operate at a high standard
• Work with senior engineers who will mentor your growth into deeper ownership
• Execute combustion CFD tasks using high-fidelity methods for flow prediction and combustion dynamics
• Design and execute rig tests and reduce data
• Collaborate across disciplines including compressor exit, turbine inlet, SAS, mechanical design, and materials
• Contribute to cycle-level impact analysis, such as combustor influence on Specific Fuel Consumption (SFC), thrust-to-weight ratio (T4), and hot section life

The Ideal Candidate

• 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
• Work experience in cycle-level impact

What Sets You Apart

• Component or module ownership experience in a turbomachinery program or product
• Supersonic jet engine or gas turbine engine design experience
• Part 33 commercial certification experience
• Background in developing design tools, methods or processes
• Testing and data-reduction experience
• A strong desire to avoid bureaucracy and move fast in a dynamic environment

Compensation

• P2 Level - Typically 0 - 5 years of experience - Base salary range: $85,000 – $105,000
• P3 Level - Typically 5 - 10 years of experience - Base salary range: $105,000 – $130,000
• P4 Level - Typically 10 - 15 years of experience - Base salary range: $130,000 – $170,000

Benefits

• Competitive cash compensation
• Significant equity grants with upside potential
• Flexible PTO
• A suite of progressive benefits designed to support employees' well-being and growth
