The market opportunity for OSS types of products is expected to grow to over $2 billion in size.

OSS is seeking a hands-on, detail-oriented Quality Engineer with three to five years of relevant experience to support product, process, supplier, and quality-management-system performance in an AS9100D-certified manufacturing environment. This mid-level position combines inspection and product assurance with root-cause analysis, corrective action, supplier quality, audit support, quality metrics, and continuous improvement. The Quality Engineer will independently handle routine quality-engineering activities, contribute to cross-functional problem solving, and receive guidance from the Quality Manager on complex, high-risk, or customer-sensitive issues.

The Quality Engineer will report to the Quality Assurance Manager.

Receiving and Final Inspection

• Perform receiving, in-process, and final inspections and support the preparation and review of First Article Inspections and First Article Inspection Reports (FAIRs) in accordance with AS9102.
• Inspect electro-mechanical parts and assemblies, sheet metal and machined components, printed circuit boards (PCBs), printed circuit board assemblies (PCBAs), and related hardware.
• Interpret engineering drawings, specifications, tolerances, geometric dimensioning and tolerancing (GD&T), surface-finish requirements, workmanship standards, and customer quality notes.
• Perform visual inspections of plating, coatings, chemical conversion coatings, paint, cosmetic surfaces, soldering, conformal coating, and other applicable finishes or special processes.
• Select and use appropriate inspection equipment, including calipers, micrometers, height or drop gages, pin gages, thread gages, go/no-go gages, microscopes, surface plates, and other precision measuring tools.
• Ensure inspection records, reports, and related documentation are complete, accurate, traceable, and processed in a timely manner.

Product Quality and Manufacturing Support

• Assist with the development, implementation, and maintenance of inspection plans, control plans, sampling plans, acceptance criteria, and inspection methods; independently maintain assigned inspection documentation.
• Support production-floor quality issues, monitor First Pass Yield (FPY), and help improve manufacturing quality throughout the production cycle.

Nonconformance, Root Cause, and Corrective Action

• Administer Nonconformance Material Reports (NCMRs/NCRs), support material-review and disposition activities, and coordinate assigned temporary deviations or controlled exceptions when authorized.
• Support root-cause investigations and corrective actions under the guidance of the Quality Manager, independently leading appropriately scoped investigations using methods such as 5 Whys, Fishbone (Ishikawa), and DMAIC tools.
• Prepare, coordinate, and follow up on Corrective Action Reports (CARs), Supplier Corrective Action Requests (SCARs), and other corrective or preventive actions.
• Collect and evaluate objective evidence to support corrective-action effectiveness verification and confirm that assigned actions address the identified root cause.
• Investigate manufacturing defects, assembly failures, customer complaints, field failures, returns, supplier escapes, and containment issues.
• Identify design-related or process-related contributors to quality issues and work with Engineering and Operations to reduce scrap, rework, escapes, and recurrence.

Quality Management System and Audit Support

• Support ongoing compliance with AS9100D, ISO 9001, ISO 14001, customer-specific requirements, and applicable regulatory requirements.
• Prepare for and participate in internal audits, registrar audits, customer audits, supplier assessments, and TUV or UL facility audits, as applicable; support audit follow-up and closure of assigned findings.
• Support the process approach, risk-based thinking, document control, configuration management, product traceability, product safety, counterfeit-parts prevention, and Foreign Object Debris (FOD) prevention.
• Assist with creating, updating, and reviewing quality procedures, work instructions, inspection instructions, the Quality Manual, the Procedure Manual, and controlled quality records; provide training on assigned processes and documents.
• Maintain assigned portions of the Master Documentation Register and support document-control activities to ensure quality documents are current, approved, and properly controlled.
• Review purchase orders, customer quality clauses, specifications, and contract requirements to confirm quality obligations are identified and implemented.
• Support the calibration system for inspection, measuring, and test equipment, including record maintenance, recall coordination, and follow-up on overdue or out-of-tolerance equipment.

Supplier Quality

• Work with suppliers and Supply Chain to resolve assigned quality issues and support supplier selection, approval, development, and ongoing performance monitoring.
• Support supplier audits, remote assessments, receiving-inspection planning, and supplier risk evaluations; participate in onsite supplier activities as experience and business needs require.
• Review supplier FAIRs and supporting objective evidence for compliance with AS9102 and customer requirements.
• Coordinate assigned supplier escapes, containment activities, corrective actions, and improvement actions, escalating significant risks or recurring issues to the Quality Manager.
• Maintain and analyze supplier scorecards and key performance indicators, including On-Time Delivery (OTD), Parts Per Million (PPM), Cost of Poor Quality (COPQ), corrective-action responsiveness, and other risk or performance measures.
• Support maintenance of the Approved Vendor List and communicate supplier-quality performance to Supply Chain and cross-functional stakeholders.

Quality Metrics and Continuous Improvement

• Analyze assigned quality data and communicate trends, risks, and improvement opportunities using quality metrics and objective evidence.
• Track and report CORE process KPIs, Quality Objectives, FPY, nonconformance trends, supplier performance, corrective-action aging, and other departmental measures.
• Apply foundational quality-engineering methods such as risk assessment, sampling plans, basic Statistical Process Control (SPC), and data trending; participate in FMEA, process-capability (Cp/Cpk), and Gage Repeatability and Reproducibility (GR&R) activities with guidance as appropriate.
• Participate in Lean, Six Sigma, and other continuous-improvement projects and lead appropriately scoped improvement activities that enhance product quality, process capability, cost, delivery, or customer satisfaction.
