Quality Control Engineer

Full-time, [compensation to be added]

Approximately 10-15%, primarily to contract manufacturer sites in Mexico

The QC Engineer is a founding member of the Quality Control function, which is accountable for the quality of product going to the field. This is a hands‑on engineering role. You will perform functional validation testing, inspect customer returns, run audits, diagnose failures, and turn findings into clear technical evidence that holds contract manufacturers to Inovonics requirements. Success is measured by how well defects are caught before they reach customers, how well failures are understood, and how quickly findings move to corrective action.

• Functional Validation Testing: Perform functional validation testing on sampled product against written test procedures, using bench equipment such as power supplies, oscilloscopes, and multimeters along with contract manufacturer test fixtures. Develop and improve test procedures as products and failure modes change. Log results, capture failures with supporting data, and drive them to a cause.
• Failure Diagnosis and Root Cause: Diagnose failures at the circuit and system level by measuring supply current, voltage rails, and signal behavior. Run structured root cause investigations (5 Whys, 8D, FMEA) and elevate to Engineering when a failure needs deeper design analysis.
• RMA Inspection: Inspect and functionally test returned units against a prioritized backlog with set turnaround targets. Classify each return as a known issue, a new failure, customer damage, or no fault found, and record the failure mode from a standard list. Capture as‑received photos, label photos, and test logs as evidence for warranty and charge decisions. Feed return data back to Engineering, Manufacturing Engineering, and the contract manufacturer scorecard.
• Incoming Inspection and Finished Goods Validation: Define and run sampling plans for incoming lots from each contract manufacturer using ANSI/ASQ Z1.4, with AQL set by product risk tier. Run recurring validation to detect production drift. Make accept, reject, and escalation decisions and document results.
• Triggered Audits: Run audits when customer signals appear, such as return‑rate spikes or customer non‑conformance trends, and report what the data shows.
• Contract Manufacturer Management: Write clear technical findings (data, photos, test results, failure analysis) that Manufacturing Engineering uses to issue CAPAs and SCARs. Co‑own the contract manufacturer scorecard, verify that corrective actions hold in later lots, and travel to Mexico for on‑site audits.
• Charter and Standard Work: Help shape and run the QC charter, including AQL values, validation cadence, and audit priorities. Build and maintain QC procedures and work instructions, and serve as the QC contact for Engineering, Manufacturing Engineering, and Operations.
• Data and Continuous Improvement: Apply SPC and lean principles to inspection and test data, report QC results to the Director of Quality, and lead improvement projects.
