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.   Why Credo

• Purpose: We invest in what matters. From meaningful-future shaping projects to competitive compensation, we empower you to grow your career while making a lasting impact.

• People: Connection starts within. We collaborate, celebrate wins, and create an environment where everyone can do their best work.

• Possibilities: Our belief shapes what’s next. Our technology powers the most reliable and energy-efficient connections around the world – and our team powers new products and markets that come next.

Qualifications

Basic Qualifications • Hands-on experience with Cadence Virtuoso or similar layout software (e.g., analog IC layout tools).

• Experience with DRC/LVS, foundry PDKs, and layout verification methodologies.

• Familiarity with foundries PDKs.

• Ability to build and maintain automated layout structures (PCells/SKILL scripting or equivalent).

• Strong communication skills and ability to work in cross-functional teams.   Preferred Qualifications • Background in silicon photonics fabrication processes.

• Experience with mixed photonic-electronic layout integration.

Responsibilities

• Develop and implement mask layouts for photonic integrated circuits using Cadence Virtuoso or similar software.

• Create and maintain PCells for photonic building blocks (waveguides, couplers, modulators, gratings, etc.).

• Perform waveguide routing, ensuring correct connectivity, bend radius limits, and low-loss optical paths.

• Verify layouts using DRC, and LVS to ensure compliance with foundry requirements.

• Collaborate with device designers to translate basic schematics and specifications into Software schematics and manufacturable layouts.

• Optimize layouts for performance, yield, and compactness while adhering to technology constraints.

• Participate in photonic design automation tool development and workflow improvements.

• Prepare and manage data for tape-out and support mask review processes.

• Debug layout and rule-check issues and propose corrective actions.
