As part of the development of EV battery cell& modules, define with the ACC AFS entities the tests to be carried out in accordance with the availability of ACC equipments, ressources and priorities defined.
- Analyze the Customer EV data related to ACC product, the ACC manufacturing data and define tests set-up and pass failed criteria in order to confirm or not the customer preliminary hypothesis and analyis.
- With the support of Protoline/TestFactory tests results and deviation with our internal standards/specifications analyze the raw data and identify the potential root causes of the failed ACC product.
- To support the customer on their site for deeper analysis for more complex or hazard failure.

As a Technical AfterSales Validation Engineer, you are responsible for defining and technically monitoring the AfterSales activities to which you are assigned:

o You act as the main technical contact with all stakeholders involved in processing the claim (ACC AFS entities, GigaF Quality, Diagnostic center/TestFactory/analytical lab, ACC logistics, Resident Engineer, and Customer technical AFS services).

o You define and develop the test plan to confirm the defect and identify the root causes by interacting with experts (chemistry, mechanics, electrical,..).

o You release a synthetesis report of the tests conducted and the identified failure mechanism.

o You write lessons learned (RETEX) for production plants and for Resident Engineers to make them autonomous in handling similar future failures.

o You act as a "Flying Doctor" on a customer's site to carry out initial diagnostic operations or safety measures before shipment.

Additionally, You ensure the test plan is followed and provide evidence of the failure:

o You issue Test Requests to the Diagnostic center and TestFactory.

o You write all test procedures, ensuring they comply with HSE and AFS entities requirements and constraints: procedure, means, expected results, timing, etc.

o You check the progress and monitoring (technical planning, KPI work package) of the tests.

o You analyze the raw data from various tests/teardowns and analytical lab data with the support of experts or designers if needed.

o You continuously shared lessons from experience throughout the different ACC entities and propose improvements to prevent recurrence.

Moreover, You interface with ACC/Customer AFS teams:

o You are the technical reference to remotely support teams at customer sites by guiding them in diagnostics or technical activities to facilitate initial analysis of the failure.

o You are the technical reference who physically supports on-site customer expertise or activities related to packaging/disassembly/shipment of faulty products at customer AFS sites.

o You rely on the V&V AFS manager and GigaFactory Quality Plant services to define additional controls to eliminate and/or detect identified failures before shipment to the customer.

o You regularly report the status of identified failures to improve validation teams' understanding of requirements to strengthen tests impacting product specifications (reliability, safety, performance criteria, etc.).

o You monitor product specification changes, as well as validation plans conducted by product engineering teams, to update documents/tests to be performed in case of SAV returns and to train teams at customer sites.
