About the role

About the Role

Join an early-stage consumer AI company as its founding product engineer, with ownership of an AI assistant and its end-to-end user experience. You will work across agent behavior, product interfaces, and evaluation systems to help make everyday tasks easier for users.

What You'll Do

  • Build the agent decision-making layer, including tool-calling loops, memory, context assembly, prompt design, and model routing.
  • Create evaluation infrastructure with conversation replay, turn-level assessments, and regression suites to guide release decisions.
  • Own product experiences across mobile and web, from onboarding and initial interactions to ongoing use, group conversations, approvals, and trusted networks.
  • Ship features end to end, using experimentation and feature flags to measure outcomes and improve the product.
  • Develop integrations with email, calendars, bookings, payments, and browser automation, including reliable tool-use and user-approval flows.
  • Review conversations, speak with users regularly, and use feedback and product data to prioritize improvements.
  • Set engineering standards and help grow the team while remaining hands-on.

What We're Looking For

  • At least 4 years of software engineering experience at an AI product company, AI lab, or consumer product company shipping products at scale.
  • Production experience building agents with tool use, memory, and long-running conversations, along with evaluation systems that inform shipping decisions.
  • Full-stack experience with TypeScript, React, Next.js, and Postgres.
  • Experience with third-party APIs, OAuth, payments, or agent tools such as function calling, MCP servers, and browser automation.
  • A record of owning features end to end and demonstrating measurable product impact.
  • Strong product judgment, consumer experience sensibility, and fluency with AI-assisted development, including verifying and owning shipped work.
  • Experience leading a growing engineering team while staying hands-on, and evidence of sustained contribution at an employer or deep technical expertise.
  • Post-training or fine-tuning experience is a plus.

Compensation & Benefits

Base salary: $200,000 to $300,000 annually. Visa sponsorship is not available.
