What are the responsibilities and job description for the Intern, System Modeling - Mixed Signal Modeling and Analysis position at Ayar Labs?
Term: May through August, 2026
Department: Engineering
Please Note
Ayar Labs, the global leader in optical I/O chiplets, is harnessing silicon photonics to revolutionize the scaling of AI compute hardware. Our system modeling team is a key contributor to defining, simulating, and refining system architectures using highly refined device models and simulation tools to meet performance metrics across various manufacturing, product lifetime, and environmental corners. We are looking for motivated undergraduate or graduate interns to join our system modeling team, where you will develop mixed signal modeling and design methodologies that bridge the gap between the system model and device/subsystem design. In this role, you will work at the intersection between system modeling and mixed signal design to refine device/subsystem models and analyze their impact to system performance. Projects are tailored to your experience and interests, and you will be mentored by a senior engineer as you work alongside with Ayar Labs engineers to help drive the optical I/O revolution.

About Ayar Labs
At Ayar Labs we’re about to revolutionize computing by moving data with light. We’re unleashing processing power for artificial intelligence, high performance computing, cloud and telecommunications by removing the bottlenecks created by today’s electrical I/O -- making it possible to continue scaling computing system performance. Ayar Labs is the first to deliver an optical I/O solution that combines in-package optical I/O chiplets and multi-wavelength remote light sources to replace traditional electrical I/O. This silicon photonics-based I/O solution enables chips to communicate with each other from millimeters to kilometers, to deliver orders of magnitude improvements in latency, bandwidth density, and power consumption.
With our strong collaborations with industry leaders and government, our deep ties to MIT and UC Berkeley, and our commitment to hiring the best engineers in photonics and electronics, joining our team gives you the opportunity to collaborate with renowned experts on challenging, paradigm-shifting work.
We are passionate about delivering in-package optical I/O at scale, leveraging the strength of our patent portfolio and our team of leading interdisciplinary experts. We believe that deep cross-collaboration between teams facilitated by honest, open debate is the best way to drive innovation and achieve big wins. Join our team and experience the possibilities.
Ayar Labs is an Affirmative Action/Equal Opportunity Employer and is strongly committed to all policies which will afford equal opportunity employment to all qualified persons without regard to age, sex, national origin, race, color, ethnicity, creed, religion, gender identity, sexual orientation, disability, veteran status, or any other characteristic protected by law.
