About Us: Voyant Photonics, based in the heart of New York City, is transforming machine perception with a new class of LiDAR devices that are compact enough to fit in the palm of your hand and powerful enough to measure range, velocity, and reflectivity with unparalleled accuracy. By leveraging cutting-edge silicon photonic chips smaller than your fingertip, we deliver sensors that are not only revolutionary in performance but also affordable enough to integrate into any system. Our technology disrupts the status quo of bulky, expensive, and power-hungry LiDAR systems, making high-precision sensing accessible for widespread adoption in robotics, autonomous vehicles, drones, industrial automation, and beyond. With Voyant, the next generation of machines can see, understand, and navigate the world like never before. Discover how we’re redefining what’s possible by making real products out of cutting edge research in silicon photonics. Why Join us? At Voyant, you’ll help build some of the world’s most complex silicon photonics chips, reimagined for high-performance 3D sensing. Our chips are at the heart of our LiDAR systems, and your work has a direct impact on our core product and roadmap. As a Senior Silicon Photonics Engineer, you’ll play a key role in defining photonic architecture and developing new passive and active components. In your first year, you’ll own simulations, and design system PICs, working hands-on from concept through implementation. You’ll join a small, fast-growing team that collaborates tightly across photonics, systems, packaging, and electronics. The role offers both deep technical ownership and real growth potential — from leading component design to eventually overseeing full tapeout efforts across disciplines. If you're excited by cutting-edge technology and meaningful challenges, this is a rare opportunity to shape a core system in a company that’s bringing photonics innovation to market.
