CNC Programmer

Boom Supersonic’s mission is to make the world dramatically more accessible through a renaissance in supersonic flight. Boom is developing the Symphony supersonic engine, which powers the Overture supersonic airliner and the Superpower natural gas turbine for AI. Overture will fly at twice the speed of today’s subsonic jets over water and 50% faster over land with Boomless Cruise.

Start the Best Work of Your Career at Boom

Standing up a new machine shop from scratch isn’t about business as usual—it’s about building the backbone of how we design, cut, and deliver hardware at supersonic speed. At Boom, we’re bringing CNC programming capability in-house so we can iterate faster, verify programs in process, and adapt on the fly.

This is not a role where you inherit proven toolpaths and push “go.” You’ll be programming complex aerospace parts, testing your work on the floor, and shaping the standards for how Boom machines everything from prototypes to production hardware.

Role Overview

• Develop CNC programs for 5-axis mills, mill-turn, and multi-spindle equipment.
• Validate and optimize programs directly at the machine, ensuring tight feedback between virtual programming and real-world cutting.
• Partner with machinists, NC programmers, and engineers to translate design intent into efficient, high-precision toolpaths.
• Establish workflows, revision control, and programming standards as Boom scales its machining capability.
• Support rapid prototyping and adapt programs quickly as engineering designs evolve.
• Build and maintain robust tool libraries, workholding strategies, and process documentation.
• Mentor less experienced programmers and machinists, sharing best practices and developing team capability.

The Ideal Candidate

• Expert in CNC programming for 5-axis milling and mill-turn machines.
• Hands-on experience with ESPRIT EDGE, hyperMILL, MasterCAM, NX, or CATIA
• Deep understanding of machining fundamentals—feeds, speeds, chip control, tooling, fixturing, and material behavior.
• Proven ability to troubleshoot post processors, toolpaths, and machine setup issues.
• Experience programming tight-tolerance aerospace or other high-performance parts.
• Collaborative and curious—comfortable working shoulder-to-shoulder with machinists and engineers.
• Demonstrates a strong work ethic and ambition, complemented by effective collaboration skills in a team setting.
• Excels in a high-energy, independent, and challenging work environment.

What Will Set You Apart

• Experience machining aerospace materials such as titanium, Inconel, and nickel superalloys.
• Background with Mazak machines, virtual machine model verification, and post processor tuning.
• Ability to architect efficient tool management systems and shop standards.
• Exposure to both prototype and production machining environments.
• Startup or greenfield manufacturing experience—helping stand up processes and infrastructure from day one.

Compensation

The Base Salary Range for this position is $86,000 - $109,000 per year. Actual salaries will vary based on factors including but not limited to location, experience, and performance. The range listed is just one component of Boom’s total rewards package for employees. Other rewards may include long term incentives/equity, a flexible PTO policy, and many other progressive benefits.

There is no set deadline to apply for this job opportunity. Applications will be accepted on an ongoing basis until the search is no longer active.

ITAR Requirement

To conform to U.S. Government aerospace technology export regulations (ITAR and EAR), applicant must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State. Learn more about ITAR here.
