Full Job Description
The Role

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.

What You'll Do
  • Own features end-to-end in our TypeScript and Next.js codebase, from ideation to launch, while holding an exceptionally high bar for UX and design quality.
  • Build scalable full-stack systems, polished UIs, robust developer-facing APIs, and the SDK layer that ties them together.
  • Optimize performance and latency across the entire stack to ensure seamless, real-time user experiences.
  • Work closely with research and model engineering to shape how our voice AI capabilities are experienced in the product.
  • Contribute to our core architecture, ensuring seamless integration between our UI, SDK, and platform.
What You'll Bring
  • Proven track record: You've built and shipped beautiful products before and can point to production work you're incredibly proud of.
  • Product & Design Intuition: You care deeply about design, animation, and UX. You have strong taste and the confidence to defend it.
  • Full-Stack Proficiency: You're comfortable across the full stack: frontend, backend, APIs, and everything in between.
  • Execution Mindset: You set direction, own decisions, and get things across the finish line. Shipping is a skill you have mastered.
  • Autonomy: You thrive in environments where you can be autonomous, opinionated, and move fast.
Nice To Have
  • Experience building real-time or streaming applications (WebSockets, WebRTC, audio/media APIs).
  • Experience with monorepo setups using Turborepo or similar tooling.
  • Experience with modern UI animation libraries (like Motion/Framer Motion) to build fluid, organic interfaces.
  • Familiarity with voice, telephony, or conversational AI products.
  • You are a former product lead or startup founder.
Benefits
  • Top-tier compensation: in order to get the best talent, we provide salary and equity that recognize your skillset
  • 🥗 Meals: free breakfast, lunch, and dinner provided in the office
  • Healthcare: Comprehensive health, dental, and vision
  • We have regular off-sites and team celebrations
