Metrology Specialist

Radiant Industries•El Segundo, CA

11d•Onsite

About The Position

Radiant is an El Segundo, California-based company building mass-produced, transportable nuclear microreactors. Its first reactor, Kaleidos, is a 1-megawatt system designed for factory construction and deployment wherever power is needed. Radiant was founded in 2020 and has contracts with the U.S. Army, Navy, and Air Force, as well as pre-order agreements with Equinix, with deployments beginning in 2028. The Metrology Specialist will help build and advance Radiant’s precision measurement and verification capabilities as the company scales advanced reactor manufacturing. This hands-on technical role serves as an expert in dimensional metrology, precision inspection, and measurement technologies, ensuring components and assemblies can be reliably verified against engineering requirements. The specialist will perform complex dimensional inspections, develop measurement strategies, program and operate Coordinate Measuring Machines (CMMs), and collaborate with Engineering, Manufacturing, and Quality to solve measurement challenges. The role also helps build Radiant’s metrology and verification capabilities by evaluating and implementing measurement equipment, developing inspection methodologies, and establishing infrastructure to support more complex hardware and higher production volumes. The specialist will contribute to the company’s approach to precision measurement, automation, and dimensional verification throughout the product lifecycle. The position is 100% onsite at Radiant’s El Segundo headquarters; extended hours and weekends may be needed as necessary.

Requirements

3–7 years of relevant experience in dimensional metrology, precision inspection, manufacturing quality, or a related technical environment.
Hands-on experience programming and operating CMMs, including developing measurement routines and evaluating inspection results.
Strong understanding of GD&T, including ASME Y14.5 principles and applications.
Experience interpreting complex engineering drawings, CAD models, dimensional tolerances, and technical specifications.
Proficiency with precision measurement tools such as micrometers, calipers, height gauges, and bore gauges.
Understanding of measurement accuracy, repeatability, reproducibility, measurement uncertainty, and calibration principles.
Ability to develop effective measurement and inspection approaches for complex geometries, tight tolerances, and challenging part configurations.
Strong technical problem-solving skills, including investigating dimensional discrepancies and recommending practical solutions.
Ability to work independently and collaborate effectively with Design Engineering, Manufacturing, and Quality teams.
Strong attention to detail, technical documentation skills, and commitment to accurate, defensible inspection results.
Willingness to work extended hours and weekends as necessary.
Must work 100% onsite at Radiant’s El Segundo headquarters.

Responsibilities

Serve as Radiant’s metrology subject matter expert, providing technical guidance on precision measurement, dimensional inspection, measurement uncertainty, and verification methods.
Perform complex dimensional inspections using CMMs, precision measurement instruments, and other inspection technologies to verify components and assemblies against engineering specifications.
Develop and optimize CMM programs, measurement routines, inspection setups, fixturing strategies, and reporting methods to improve accuracy, repeatability, and efficiency.
Evaluate, select, qualify, and implement metrology equipment, technologies, and inspection methods.
Collaborate with Engineering and Quality to develop inspection strategies for critical dimensions, geometric tolerances, and product characteristics.
Apply GD&T and dimensional metrology principles to interpret drawings, identify measurement challenges, and establish verification approaches.
Support design for inspectability by working with Design and Manufacturing Engineering early in development to make dimensional requirements measurable, practical, and achievable.
Establish and improve metrology processes, including measurement procedures, inspection methodologies, equipment verification, measurement system analysis, and standardized reporting.
Identify opportunities to improve measurement throughput, integrate digital inspection tools, and reduce manual inspection effort.
Support equipment calibration requirements, qualification, maintenance, and traceability to recognized measurement standards.
Investigate measurement challenges, support root cause analysis, resolve discrepancies, and distinguish product variation from measurement-system variation.
Partner with Engineering, Manufacturing, Supply Chain, and Quality to develop practical measurement solutions supporting product integrity, manufacturing readiness, and scalability.
