Software Engineer, Frontend

As a Frontend Engineer at Phonic, you'll build the product layer that brings our voice AI to life for customers. From the real-time interfaces that power live voice conversations to the dashboards, APIs, and developer tooling that our customers rely on daily—you'll own the full surface area of what users see and interact with. You'll work in close collaboration with our research and ML teams to translate cutting-edge voice AI capabilities into polished, production-grade product experiences.

This is a role for a builder who cares deeply about craft, moves fast, and isn't afraid to take end-to-end ownership of features from design to deployment.

We’re a small team of researchers and engineers from MIT, Stanford, CMU, MosaicML, Citadel, and Genesis Therapeutics, including former founders, an IMO medalist, and an International Linguistics Olympiad medalist. We work in person in San Francisco five days a week. Everyone here is unusually obsessed with our customers: we’ll happily spend hours perfecting the way our model reasons while it talks, or the way it makes a caller feel heard, going as deep into the stack as it takes.
