About Quintessent

The resurgence of chip investments has driven an upward inflection in the performance of individual compute chips, but the ability of those chips to communicate with one-another has not kept pace. Communication, not computation, is now the system level bottleneck in large-scale computing and AI applications.

Quintessent is developing connectivity solutions to break the chip communication bottleneck and future-proof compute scaling.

About the role

Build the interconnect platform that powers the next generation of AI infrastructure.

Quintessent is taking on some of the hardest challenges in optical connectivity – directly

attacking the foundational bottlenecks limiting the scalability and reliability of next-generation AI

and computing infrastructure. Our team has trailblazed pioneering work in quantum dot lasers

and amplifiers, heterogeneous integration, and multi-wavelength silicon photonics. We are

converging innovations in materials science, process integration, chip and system design to

build products that we believe will form a core part of AI networking systems.

We are a scrappy, high-trust team that takes ownership, stays humble, and believes in tackling

hard problems with speed, intellectual honesty, and relentless improvement. We hold ourselves

to a high bar starting from a deep understanding of our customers’ problems. If this sounds like you, and you want to build the optical interconnect platform that powers the next generation of AI infrastructure, we’d love to talk.

Join our elite technical team driving the delivery the next-generation of DWDM optical interconnects.

What you'll do

• Develop and execute automated test/validation plans to quantify device performance
• Develop and execute automated data analysis to inform photonic circuit architectures
• Contribute to photonic control architecture/algorithm development & validation
