## Description

ASIC-PD team is hiring both junior and senior engineers, whose work scope is physical design from RTL to GSDII: design quality check, synthesis, formal check, partitioning, constraint (for both design and process), async check, timing analysis/fixing/signoff, also all related flow. Join us, you will work together with expertise in all these areas; you will not only work for physical application, but also drive physical friendly design with all related teams: ASIC/P&R/DFT/SI/ARCH etc.; you will work for the most advanced process/technology, the biggest chip in the world.

**What You’ll Be Doing**

- Invent and optimize new methods for increasing chip frequency while minimizing power consumption across a suite of internal optimization tools.
- Improve algorithms (in C++) for IR drop optimization, simulation
- As with any software engineering team, we do write a lot of code, but this is broader than a typical CAD or EDA role. Instead, we as a team own the whole process from discovery and invention of new optimization opportunities, to developing solutions and working directly inside design teams to facilitate deployment.

**What We Need To See**

- BS, MS, PhD in Electrical Engineering or Computer Science or equivalent experience
- Minimum 2+ years of relevant experience in CAD software and VLSI hardware design
- Strength in both CAD software and VLSI design
- Understanding of VLSI IR drop optimization or simulation and related concepts, including constraints, corner, CCSP, FSDB etc.
- Demonstrated ability in software development using C++
- Strong communication and interpersonal skills

**Ways To Stand Out From The Crowd**

- Familiarity with RedHawk and typical design flows written in Perl, Tcl, and Python.
- C++14 or newer experience, such as lambdas and concurrency
- Experience in high-performance software design including multithreading, distributed computing, efficient memory, and I/O use, etc.
- Experience in IR drop optimization, calculation
