Semiconductor Assembly Mass Production Engineer

Job Description

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

Initially, the successful candidate will be responsible for manufacturing sites with relatively low production volumes to become familiar with our operations and processes. The scope of responsibility will then be gradually expanded to additional sites.

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 join the team and grow together with us.
