## Job description

Lead the development of CPU Subsystems (CPUSS), a core component of next-generation microcontrollers. Drive the architecture definition, specification development, design, and verification of CPU subsystem components, including CPU cores, caches, memory protection mechanisms, debug and trace features, interrupt controllers, and bus interfaces. Develop and optimize CPU subsystem solutions for performance, power, and area, while leading RTL design, verification strategies, and the implementation of functional safety and security features.

You will also evaluate and introduce new technologies, design methodologies, and architectural innovations for future CPUSS products. Collaborate with global engineering teams and external partners to deliver high-performance, high-quality CPU subsystem solutions from concept through product realization.

## Qualifications

＜Must Have＞ Self-motivated individual with a proactive attitude and a strong willingness to take on new challenges. Experience in logic design and/or functional verification for LSI or IP development. Fundamental knowledge of microcontrollers, SoCs, CPU architectures, and CPU-related peripheral circuits. Experience leading development activities as a project leader, sub-leader, or technical focal point, including coordinating and guiding multiple team members toward successful project execution. 〈Nice to Have〉 Solid understanding of CPU architectures, bus protocols, and CPU peripheral circuits.

Experience with logic synthesis, non-functional verification (such as CDC, RDC, DFT verification) and timing verification. Broad understanding of semiconductor development beyond logic design, including DFT, physical design, and backend implementation, with the ability to effectively collaborate and communicate with engineers across different design disciplines. Experience managing development projects involving domestic and offshore external partners.

Knowledge of functional safety and cybersecurity/security technologies.
