【Gunma】Semiconductor Assembly Mass Production Engineer

We are seeking an experienced back-end assembly engineer specializing in FCBGA and WLCSP, including support for the R-CAR series, one of Renesas’ key automotive product lines.

The successful candidate will initially take primary technical responsibility for FCBGA/WLCSP products manufactured at both domestic and overseas internal manufacturing sites and OSATs. In the future, the scope of responsibility is expected to expand to cover a broader range of flip-chip package technologies, including Chiplet packages.

As a significant portion of the products are manufactured by overseas OSATs, we expect the candidate to take a proactive approach to communication and collaboration in both Japanese and English.

As this is a replacement hire following the departure of the previous engineer, we are ideally looking for an experienced professional who can make an immediate contribution. At the same time, strong support will be available from the experienced direct manager, and we welcome someone who is motivated to contribute to the team and continue growing together with us.

• Mass Production: Assembly yield, cost, and quality improvement activities; management of product/process changes; and coordination with relevant functions.
