Responsibilities

~1 min read
  • Own a core product domain end-to-end (for example the B2B business platform, the voice/SMS/email agent layer, the underlying data/AI graph, or a new consumer product)
  • Talk directly to customers, turn their feedback into product decisions, and ship the work yourself
  • Build and tune multi-modal agents for low-latency voice, strong messaging response rates, and durable conversation state across channels
  • Set the architecture and quality bar for non-deterministic systems: evals, prompt versioning, guardrails, and drift detection
  • Work across the full stack, from React/Next.js on the front end to Node.js services and Python voice pipelines

Tech stack: TypeScript, Node.js, Next.js, React, Python, LiveKit, Deepgram, Redis, plus modern LLM and agent tooling (Anthropic/OpenAI SDKs, Vercel AI SDK, Mastra, Braintrust)

Requirements

~1 min read
  • 3–8 years of full-stack engineering experience
  • Track record shipping a product from zero to one, whether at a high-growth startup, as a founder, or on a new-product team inside a larger company
  • Strong command of TypeScript across the stack (Node.js and React/Next.js)
  • Comfortable owning product decisions without a PM, including speaking directly with customers
  • Real, hands-on depth in at least one relevant area: production voice or SMS agents, long-running agent state and memory, B2B2C or marketplace products, or agent evaluation and guardrails
  • Genuine product experience building with LLM APIs or agent SDKs (not tutorials or thin wrappers)

Nice to Have

~1 min read
  • Prior experience as a founder or at an accelerator-backed startup that gained real traction, with the perspective to reflect on what worked and what didn't
  • Degree from a strong computer science program (weighed more heavily for candidates at the earlier-career end of the range)
  • Python experience with real-time voice pipelines (LiveKit, Deepgram, STT/TTS) or with evaluation tooling
