A Resident Quality Engineer represents the supplier inside the customer’s plant: handles complaints, coordinates containments, and follows up on corrective actions. RIDYS Group assigns resident engineers in San Luis Potosí and the Bajío region, with our own personnel under REPSE (Mexico’s Registry of Specialized Service Providers).
Their work covers supervision of the agreed production stages, detection of defects and deviations, root cause analysis of recurring problems, implementation of immediate corrective actions, and the reports the customer requires.
We provide Resident Quality Engineers who represent your company at your customer’s plant for quality follow-up, containment, and daily communication, within the agreed scope. We are ISO 9001:2015 certified and REPSE registered.

Your customer requires permanent on-site presence after an incident. You have a strategic account that demands ongoing technical interaction and your team is stretched thin. Or you need someone to represent your quality before an OEM without loading that role onto an engineer who already has their own plant to run.

It is worth stating clearly, because it is the most common confusion.
It is not an extra inspector. An inspector executes; a resident engineer represents, makes decisions on the floor within the agreed scope, and engages technically with your customer’s customer.
And it is not your personnel. The resident engineer is RIDYS personnel, with the employment relationship, social security contributions, and employer liability on our side, under REPSE registration. That distinction is what makes the arrangement hold up under review.

Before assigning anyone, we assess the operation’s specific quality needs: which product, which defects, which end customer, what interaction is expected, and on which shift.
With that, we define the profile and select the professional with the right experience for that sector and requirement. Then comes integration: the resident engineer becomes familiar with the processes, products, and equipment before taking on full responsibility.
Reports on the operation’s quality status, the period’s findings, corrective actions implemented, and follow-up on their effectiveness. Frequency and format are agreed with each customer based on what their own customer requires.
When the resident engineer attends meetings with the OEM or issue closures, they also deliver the supporting documentation those meetings require.
Continuity is the weak point of this service with most providers, which is why we address it separately.
Each assigned resident engineer works within a supervision and coordination structure that knows the account. That makes it possible to cover absences, vacations, and rotation without the customer losing service or having to onboard someone from scratch.
ISO 9001:2015 certification (Orion Registrar, ANAB accredited) and REPSE registration ARR197/2024 with Mexico’s Ministry of Labor (STPS), verifiable in the public registry. Personnel with DC-3 certificates and documented training records. Our processes are carried out in accordance with our customers’ IATF 16949 requirements.
San Luis Potosí is our operating base. We serve plants in San Luis Potosí, Guanajuato (León, Silao, Irapuato, and Celaya), Querétaro, and Aguascalientes; on request, also in Jalisco and in Saltillo and Ramos Arizpe, Coahuila.
The resident engineer can be assigned at your plant, your customer’s plant, or your supplier’s plant, depending on where the control point you need to cover is.
They are RIDYS personnel. The employment relationship, IMSS and INFONAVIT contributions, and employer liability are ours, under REPSE registration ARR197/2024.
Each account operates within a supervision structure that knows it, so absences can be covered without interrupting the service.
