Senior Engineering Technician
Radiant is seeking an CNC Programmer and Machinist who will contribute to the development of our microreactor unit. you'll be a key contributor to Radiant, programming, setting up, and operating CNC machines to produce precision components that power our most critical systems. You'll translate engineering designs into high-quality, manufacturable parts ensuring accuracy, efficiency, and innovation at every step.
This role requires hands-on experience with CNC machining, a deep understanding of G-code and CAM software, and a passion for solving complex manufacturing challenges. You'll work closely with engineers, machinists, and quality teams to push the limits of what's possible in precision manufacturing.
Responsibilities and Duties:
- Develop and optimize CNC programs for 3-axis, 4-axis, and 5-axis mills, lathes, and multi-axis machining centers.
- Set up and operate CNC equipment to validate new programs and processes.
- Read and interpret complex engineering drawings, 3D models, and GD&T specifications.
- Collaborate with design and manufacturing engineers to improve part manufacturability and reduce cycle times.
- Select proper tooling, workholding, and cutting parameters for a variety of materials (aluminum, titanium, stainless steel, Inconel, etc.).
- Troubleshoot machining and programming issues on the floor to maintain high-quality output and machine uptime.
- Continuously improve machining processes through data-driven feedback and experimentation.
- Maintain adherence to safety and quality standards across all machining operations.
- Support additional technician duties or cross-functional shop activities as needed based to achieve company priorities.
Required Skills and Qualifications:
- 5+ years of experience in CNC machining and programming in a precision manufacturing or aerospace environment.
- Proficiency in CAM software (e.g., Mastercam, Siemens NX, Fusion 360, or CATIA).
- Strong understanding of G-code, M-code, feeds, speeds, and toolpath strategies.
- Hands-on experience setting up and operating mills, lathes, and multi-axis machining centers.
- Ability to interpret complex technical drawings, GD&T, and 3D CAD models.
- Proven ability to take a part from print to finished component.
- Strong problem-solving skills and attention to detail.
Desired Skills and Qualifications:
- Experience with 5-axis machining and post-processor development.
- Familiarity with aerospace or high-performance hardware manufacturing.
- Experience with exotic materials (e.g., titanium, Inconel, carbon composites).
- Working knowledge of ERP/MES systems and digital manufacturing workflows.
Additional Requirements:
- Must be willing to work extended hours and weekends as necessary to achieve company goals.
- Must work 100% onsite at El Segundo HQ.
