Position Description

Ayar Labs, the global leader in optical I/O chiplets, is harnessing silicon photonics to revolutionize the scaling of AI compute hardware. Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models.

Backed by industry giants like NVIDIA, AMD and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next-generation AI scale-up architectures.

You will help solve the thermal and multiphysics problems that decide whether disruptive CPO succeeds, using electromagnetic, thermal, and charge-transport simulations on a leading-edge EIC-PIC process and packaging platform. You’ll get to close the loop between simulation and silicon: you’ll dig into real Validation data to learn how packaging, firmware, and device physics (such as ring-heater thermals) interact, and feed those lessons into the next submission.

Intern Skillset Needed

• Proficiency with Python
• Experience writing well-structured code and developing a code base as part of a team
• Deep understanding of photonic devices: couplers, photodetectors, electro-optic modulators, micro-ring resonators, gratings
• Experience with simulation and design tools for passive and active optical devices (e.g., FDTD, charge transport)

Education Requirements

Candidate should be actively pursuing a PhD in Electrical Engineering or other Engineering with Photonics specialization

Pay Range: $50 - 60/hourly, depending on education level
