Qualifications

• Bachelor's degree in Engineering, Quality, Materials Science, or a related technical field.
• 3–6 years of hands‑on experience in supplier quality, supplier development, or supplier reliability engineering in a regulated industry (nuclear, aerospace, defense, or medical device).
• Demonstrated ability to independently process supplier quality transactions: deviation requests, non‑conformance reports, supplier corrective action requests, purchase order quality reviews, and cert package review — without step‑by‑step guidance.
• Proven experience owning or drafting quality program documents: quality clauses, supplier requirements, inspection instructions, or equivalent.
• Working knowledge of ISO 9001, AS9100, or equivalent quality management systems, including supplier audit methods and corrective action management.

Responsibilities

• Own the supplier qualification and onboarding process end-to-end — pre-assessments, capability reviews, audit execution, and formal approval to the Approved Supplier List.
• Own, refine, and expand quality program documentation — including quality clauses, commodity-specific requirements, and the Supplier Quality Manual — building on existing foundations and authoring what doesn't yet exist.
• Develop supplier capability improvement plans — identify process gaps, partner with suppliers to close them, and track progress against defined milestones before problems reach Radiant's dock.
• Own Radiant's procurement assurance and acceptance framework — define how items are accepted across supplier types and quality levels, establish purchase order quality requirements, certifications, material traceability, and compliance documentation, and build toward a graded, systematized model.
• Execute supplier audits and manage supplier performance — audit against Radiant quality program requirements, author findings to closure, and drive structured improvement plans with emphasis on early intervention over lagging indicators.
• Partner cross-functionally with design engineering, manufacturing, and materials teams to translate technical requirements into supplier-facing quality requirements before parts are ordered.
• Process and disposition supplier quality issues when they arise — deviation requests, non-conformance reports, supplier corrective action requests, root cause analysis, and verification of corrective action effectiveness.
