Senior Engineering Test Technician

Overview

Radiant is seeking a highly skilled senior engineering test technician to support development, operation, and production ramp of our proprietary production systems.

In this role, you will work closely with engineering to execute complex, multi‑day production runs on one‑of‑a‑kind systems and transition those processes into reliable production operations.

This position requires deep hands‑on experience with hydrogen, vacuum, thermal, and automated process equipment. You will independently operate and troubleshoot safety‑critical systems, interpret real‑time process data, and make informed adjustments to ensure safe, repeatable, and high‑quality outcomes. You will be expected to understand system behavior at a fundamental level and actively drive the process.

• Independently operate and monitor complex fluid systems during extended runs, including off‑shift and overnight coverage as required.
• Execute detailed test and production profiles involving hydrogen gas, vacuum systems, furnaces, and automated controls.
• Monitor, interpret, and respond to real‑time process data, making adjustments as needed to maintain safety, quality, and process objectives.
• Troubleshoot complex system issues spanning fluid systems, vacuum hardware, electrical components, sensors, control loops, and automation.
• Support development, validation, and refinement of advanced processes in close collaboration with engineering.
• Transition validated processes into production operations and execute production work orders.
• Perform precision measurements using hand tools and metrology equipment to verify conformance to specifications.
• Operate and set up automated and semi‑automated production equipment, including laser welding systems.
• Document process results, deviations, and corrective actions to support traceability and continuous improvement.
• Support equipment maintenance, calibration, and upgrades as needed.
• Maintain strict adherence to safety, quality, and operational procedures when working with hydrogen and high‑temperature systems.
• Support additional technician duties or cross‑functional activities as needed to meet company priorities.

• 5+ years of hands‑on experience in an engineering technician, test technician, or advanced manufacturing role.
• Demonstrated experience working with complex fluid systems involving vacuum and hazardous gases.
• Experience operating thermal processing equipment such as furnaces or high‑temperature reactors.
• Strong ability to troubleshoot across multiple disciplines including mechanical, electrical, controls, and fluid systems.
• Hands‑on experience with precision assembly, cleanliness‑controlled processes, and careful material handling.
• Proficiency with precision measurement tools (calipers, micrometers, etc).
• Comfortable operating and setting up automated and semi‑automated production equipment.
• Ability to follow detailed work instructions while exercising independent judgment when conditions deviate.
• Strong problem‑solving skills and attention to detail.
• Willingness to work non‑standard hours including overnight shifts during extended runs.

• Experience with laser welding, brazing, or similar advanced manufacturing processes.
• Familiarity with hydrogen safety standards and best practices.
• Experience supporting production operations and executing work orders in a manufacturing environment.
• Background in materials processing, metallurgy, or thermal treatment processes.
• Experience working with one‑of‑a‑kind or first‑of‑its‑kind equipment.
• Familiarity with data acquisition systems, PLC‑controlled equipment, or automated process tooling.
