Senior Propulsion Engineer – Engine Mechanical Design

Senior Propulsion Engineer – Engine Mechanical Design

Join Boom Supersonic to work on Symphony, the first jet engine designed for sustainable supersonic flight.

As part of the Propulsion Team, you will own the mechanical design features that enable the Symphony turbofan to reach the airstage as fast as possible.

• Own design features covering all mechanically dynamic phenomena in the engine, including loads, actuation, rotor dynamics, and failure scenarios.
• Develop technically sound design solutions to get Symphony turbofan in the air as quickly as possible.
• Interpret, define, and review tolerances and features on part drawings.
• Create physical layouts, models, and general arrangements of modules and whole engines such as 2D cross sections, 3D models, and tolerance stackups.
• Contribute to the creation of whole engine models that incorporate structures, rotors, ducts, services routing, actuation, secondary air systems, and thermal management.
• Collaborate on specifications and design requirements for each module and help lead cross‑discipline integration efforts.
• Act as the technical owner for all mechanical aspects of the engine, including fits, seals, mounts, joints, and other components.
• Develop and implement plans for assembly and disassembly for both development and production.
• Engage in all aspects of Symphony engine development and Overture propulsion system integration, including fabrication and testing.

• Bachelor’s or Master’s in Mechanical, Aerospace, or related engineering field.
• Expert‑level experience with CAD systems such as 3DX, Catia, or NX.
• Expertise in Geometric Dimensioning and Tolerancing (GD&T).
• Familiarity with manufacturing techniques used in gas turbine production (single‑crystal casting, hollow‑core fan blades, linear friction welding, additive manufacturing, etc.).
• Leadership experience in designing turbo machinery modules and parts across different program phases.
• Ability to think through and communicate coupled engine and aircraft system‑level interactions.
• Willingness to speak, listen, give opinions, hear opinions, consider data, and build team consensus.

• Rig testing or engine testing experience.
• Supersonic jet engine design experience.
• Part 33 commercial certification experience.
• Experience with parametric modeling and PLM/PDM.
• Knowledge of heat transfer and structural analyses.
• Experience in the part disposition process.
• Background in developing design tools, methods, or processes.
• Proficiency with Python or similar programming languages.
• A strong desire to avoid bureaucracy and move fast in a dynamic environment.

• Level P3 – 5–10 years of experience – Base salary: $107,000 – $135,000
• Level P4 – 10–15 years of experience – Base salary: $133,000 – $169,000
• Level P5 – 15+ years of experience – Base salary: $160,000 – $203,000

Actual compensation will vary based on location, experience, and performance. The base range is one component of Boom’s total rewards package, which includes long‑term incentives, flexible PTO, and progressive benefits.
