 * Understanding of on-chip microcontrollers and standard peripherals, with exposure to hardware and firmware co-design.

## Description

While engaged in frontend development, your responsibilities will include working on a wide range of high-speed, powerful DSPs, silicon photonics IPs, and chips. You will participate in chip-level features, programming model and application interface definitions. You will collaborate closely with analog designers and system architects to develop micro-architecture specifications, calibration and adaptation algorithms, which then will be translated into RTL and firmware designs. For backend design, you will define, build synthesis constraints and drive timing closure. Evaluating PPA trade-offs based on synthesis and P&R feedbacks is a critical step toward the most optimized product. For post-silicon, you will actively participate in silicon bring-up, build testing scripts for debugging, characterization, performance tuning, and production. You will also work with cross-functional teams to ensure successful production.
