Representation · Stellantis Toluca
What is an SQE, and how do you work with one?
An SQE, the Supplier Quality Engineer, is the OEM representative who owns the quality relationship with a supplier. They decide how your parts are judged, whether a concern escalates, and how your scorecard reads. Working well with the SQE is one of the highest-leverage things a supplier can do.

What does an SQE actually do?
The SQE is the plant's technical gatekeeper for supplier quality. They review incoming quality, run supplier scorecards, lead problem-solving when a defect appears, decide whether to open GP-12 or Controlled Shipping, and sign off when a concern is closed. They are measured on the quality that reaches their line, which means every unresolved issue from a supplier is their problem too. Understanding that shared pressure changes how you work with them: the SQE is not an adversary to be managed around, but a partner whose job gets easier when your quality is visible and under control.
What does an SQE expect from a supplier?
| Expectation | What it looks like in practice |
|---|---|
| Fast response | An answer within the hour, not the next day |
| Data, not opinions | Counts, photos and measurements, not reassurance |
| Real root cause | 8Ds that address why it occurred and why it escaped |
| Proactive contact | Hearing about an issue from you, not from the line |
| Reliable follow-through | Commitments that are met on the date promised |
How does a Quality Liaison strengthen the SQE relationship?
A resident Quality Liaison meets those expectations in person, every working day. They attend the plant meetings, answer the SQE within the hour, bring data instead of reassurance, and follow through on commitments in front of the person who tracks them. That daily, credible presence is what turns a strained supplier relationship into a trusted one, and a trusted supplier is far less likely to see containment or a scorecard hit. It is exactly what the IDS Quality Liaison service provides at Stellantis Toluca, and it pairs with a clean 8D process. Get a representative on your side.
