About Phonic

Phonic is a product and research lab focused on powering the most realistic, human-like voice AI conversations. We've re-thought the entire stack in pursuit of this goal, from models to product, to create voice agents that feel like they truly understand you, respond emotionally and perform agentic tasks with frontier intelligence.

Our team includes top-tier AI researchers, international olympiad medalists, and former founders.

Our customers include companies that are building voice-native AI products in industries such as customer support, healthcare, and logistics. We have raised over $30M from First Round and Lux Capital.

About the Team

Phonic has a very talent-dense and close-knit team. We collaborate with high trust and are constantly trying to improve how we work to deliver world-class research and product. Everyone takes ownership in what they do and they aren’t afraid to dive in headfirst into new problems. Our team includes top-tier AI researchers, international olympiad medalists, and former founders and we’re fully in-person in our SF office.

About The Role

As a Product Engineer at Phonic, you'll own the development and delivery of platform features from ideation to launch, while upholding a high UX bar. You'll work in our TypeScript and React codebase to build scalable fullstack systems from polished UIs to robust developer-facing APIs. With a lean team, you'll have outsized influence on product direction, shaping how users interact with our voice AI models and how we prioritize what gets built.

What You'll Do

  • Own features end-to-end in our TypeScript and React codebase, from ideation through launch, holding a high bar on UX throughout

  • Build scalable fullstack systems, from polished UIs to robust developer-facing APIs

  • Work closely with research and model engineering to shape product direction and decide how users experience our platform

  • Contribute across the entire stack to ensure seamless integration across our UI, SDK, and platform

What You'll Bring

  • A track record of building and shipping beautiful products

  • Deep care for design and user experience; you have strong taste and the confidence to defend it

  • The ability to set direction, own decisions, and get things across the finish line - shipping is a skill you've honed

  • Comfort thriving in a startup environment where autonomy, opinions, and speed are the norm

  • An appreciation for simplicity: you know that shipping something clean is harder than it looks

Nice To Have

  • You enjoy being customer facing: you get dopamine from working with and shipping to customers.

  • You’re broadly excited by LLMs and the future of AI.

  • You are a former product lead or a former founder.
