CMSD develops highly configurable mixed-signal products (GreenPAKTM, GreenFETTM, PowerGreenPAKTM, and ForgeFPGATM families) for a wide range of applications such as consumer, industrial, computing, and automotive applications. A successful candidate will have in-depth system-level understanding and knowledge about semiconductor, hardware, and software development for high performance analog and mixed-signal systems in consumer, industrial, and automotive applications. The candidate will be responsible for researching technical trends and defining innovative high performance analog devices. Also, he or she will work closely with customers’ system engineering, hardware, and software teams to help define and use Renesas’s products. We are looking for someone who can build close working relationships with key customers as well as Renesas’s sales and FAE teams to define innovative products that can solve customers’ problems by understanding their needs or technical challenges customers are facing. The candidate will be responsible for conducting feasibility studies and taking the proposed product concept/ideas into a technical document (objective specification) that are the inputs to IC design teams. ### Responsibilities Listen, fully understand, and anticipate the needs of our current and prospective customers. Work with marketing team to define product roadmap and ensure that we have a plan for sustainable differentiation in the product category.
