Photonics Layout Engineer

About the role

We are looking for a Photonics Layout Engineer to join our integrated photonics design team.
 
This position is also well-suited for Analog Layout Engineers who are interested in transitioning into photonic integrated circuit (PIC) design. In this role, you will be responsible for creating, optimizing and validating PIC layouts, ensuring manufacturability, performance and compliance with foundry design rules.
 
You will work closely with device designers, process engineers and tape-out teams to deliver high-quality layouts of silicon photonics PICs. Strong candidates will have hands-on experience with industry-standard layout tools, especially Cadence Virtuoso or similar software. Understanding of photonic components, waveguide routing and automated layout generation is a major advantage. You will also contribute to layout methodologies, PCells, and design automation flows to accelerate PIC development.
 
Dustphotonics, now part of Credo, develops cutting-edge technology in Silicon Photonics which is revolutionizing connectivity and communication in data centers. Silicon photonics is becoming a standard technology used for high performance systems, solving challenges of performance, integration, power and cost. This technology is growing rapidly also in other markets such as Healthcare, LIDARs and other sensors. We are looking to solve the difficult problems, in a smart and simple way, by thinking out of the box, leveraging the knowledge and know-how of the team members and work as team to create magic.
