Product Manager, Interactive Avatar API (staff/principal-level)

Synthesia Synthesia · Multimodal · Seattle, WA · Product

Product Manager to own and scale an Interactive Avatar API from closed beta to a platform for developers. This role involves defining the API surface, developer experience, and commercial model, working closely with engineering and research teams to address real-time challenges like latency and expressiveness. The goal is to turn complex avatar technology into an easily integrable and reliable product for businesses.

What you'd actually do

  1. Owning the end-to-end Interactive Avatar API. This is the developer-facing surface (SDK, integration patterns, docs), the real-time experience quality, and the path from closed beta to general availability, and defining what the roadmap looks like over the coming cycles
  2. Getting close to the developers and teams building on the beta: understanding how they integrate, where the API fights them, which real-time behaviors make or break the experience, and what "production-ready" means to them
  3. Translating that understanding into a clear product direction. What to build, in what order, and why, and keeping the team aligned as the strategy evolves
  4. Working closely with the engineering and research teams building the real-time avatar stack; contributing clear specs, sound judgment on trade-offs (quality vs. latency vs. cost), and the context that helps them build the right thing the first time
  5. Partnering with go-to-market and commercial teams to define how the API is packaged, priced, and sold - a real-time API has a fundamentally different business model from batch video, and shaping that is part of the job

Skills

Required

  • 5+ years in product, with direct experience owning a developer-facing API, SDK, or platform product.
  • Comfortable operating in an early-stage, 0→1 environment where discovery and delivery happen in parallel and the roadmap is still being shaped
  • Strong technical fluency: you can hold a credible conversation with engineers about real-time systems, latency, and integration trade-offs, and make good calls without needing every answer handed to you
  • Strong written communication: you can write a spec, a strategy doc, or an API design rationale that others can act on without a follow-up conversation
