At Raytheon, the foundation of everything we do is rooted in our values and a higher calling - to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world. Our San Diego Manufacturing Depot provides sustainment support for legacy Raytheon magnetics products used in Aegis and Patriot Radar systems. We build and repair electrical transformers, power supplies, and magnetic assemblies utilizing expertise in coil winding, electrical assembly, soldering, encapsulation, welding/machining, and electrical testing. As a team member of the San Diego Depot Factory, a Machinist is responsible for managing and executing detailed, machined parts. We utilize horizontal and vertical mills, lathes, and other equipment in our shop. Our team often works on next-generation products that have the potential to be differentiators for our customers. This fast-paced factory is not a classic production machine shop as the work we do is anything but typical. A successful candidate will be working on projects varying from fabricating vital components for a critical production line, repair work to get essential equipment operational, or collaborating with design engineers to create a next-generation prototype. This high-speed environment requires attention to detail, ability to work with a highly skilled and diverse team, and opportunity to grow your skillset by not doing the same thing day after day. The San Diego Depot Factory's reputation is built on our ability to execute challenging projects to meet customer schedules. The successful candidate will join a small, highly skilled team directly supporting the warfighter mission. This position follows a 9/80 work schedule.

What You Will Do

• Perform advanced machining operations on mills, lathes, and other shop equipment, independently determining methods and sequencing for daily work and new assignments
• Design and fabricate custom tooling and fixtures based on practical knowledge, including when formal engineering drawings are not available
• Collaborate with design engineers to bring prototypes from concept to finished part and execute repair machining to restore essential production equipment
• Evaluate and verify part quality using established inspection controls and measurement tools while adhering to all safety standards, company policies, and industrial regulations
• Contribute to the development of machining techniques and best practices in a high-mix environment where priorities shift daily
• Review mechanical setup and execute production cycles on mill, shear, press brake, bandsaw, lathe, and CNC machines
• Program and operate CNC equipment, including automated lathes, grinders, and milling machines
• Design, fabricate, and modify custom tools, jigs, and fixtures based on hands‑on experience and practical problem‑solving—without reliance on formal engineering drawings—to address production challenges and improve workflow
• Control and optimize machine settings to achieve required tolerances and surface finishes
• Operate and inspect machinery across multiple areas, conducting quality inspections in accordance with mechanical standards
• Must have the ability to read and interpret blueprints, schematics, and work instructions.
