About the role

About the Role

Join an early-stage consumer AI company as its founding product engineer, owning the agent and the end-to-end user experience. You will shape how the assistant makes decisions, communicates, and takes action, while working hands-on across product engineering, prompts, and evaluation systems.

What You'll Do

  • Build the agent decision-making layer, including tool-calling loops, memory, context assembly, prompt engineering, and model routing.
  • Create evaluation infrastructure with conversation replay, turn-level judging, and regression suites to guide release decisions.
  • Own mobile and web product experiences, from onboarding and first interactions through ongoing use, group conversations, approvals, and trusted connections.
  • Ship features end to end, using experimentation and feature flags to measure their impact.
  • Develop integrations with email, calendars, bookings, payments, and browser automation, including OAuth and spending approval flows.
  • Review conversations and speak with users regularly to inform product decisions.
  • Establish engineering standards and help grow the team.

What We're Looking For

  • At least 4 years of software engineering experience, including work at an AI product company, AI lab, or consumer product company.
  • Production experience building agents with tool use, long-running conversations, and memory, along with evaluation systems used to inform shipping decisions.
  • Full-stack experience with TypeScript, React, Next.js, and PostgreSQL.
  • Experience with third-party APIs, OAuth, payments, or LLM agent tooling such as function calling, MCP servers, or browser automation.
  • A record of owning features end to end and delivering measurable product impact, with strong product and design judgment.
  • Comfort using AI-assisted development workflows while verifying and taking ownership of shipped code. Post-training or fine-tuning experience is a plus.
