About the Role
Join an early-stage consumer AI company as its founding product engineer, with end-to-end ownership of an AI assistant and its user experience. You will shape how the assistant reasons, communicates, and takes action, combining hands-on engineering with close product collaboration and regular user feedback.
What You'll Do
- Build the assistant's agent architecture, including tool-use loops, memory, context assembly, prompt design, and model routing.
- Create evaluation systems with conversation replay, turn-level assessment, and regression tests to guide release decisions.
- Own product experiences across web and mobile, including onboarding, follow-ups, group conversations, approvals, and trusted-network features.
- Ship features from discovery through experimentation and launch, using user feedback and product data to guide iteration.
- Develop integrations with services such as email, calendars, bookings, and payments, along with reliable approval and recovery flows.
- Review conversation transcripts, speak with users, and help set engineering standards as the team grows.
What We're Looking For
- At least 4 years of software engineering experience at an AI product company, AI lab, or consumer product company.
- Production experience building agents with tool use, memory, and long-running conversations, plus evaluation systems trusted for release decisions.
- Full-stack experience with TypeScript, React, Next.js, and Postgres.
- Experience with third-party APIs, OAuth, payments, or agent tooling such as function calling, MCP servers, or browser automation.
- A record of owning features end to end and demonstrating measurable product impact.
- Strong product judgment, experience with AI-assisted development workflows, and the ability to validate and take responsibility for shipped work.
- Experience leading a growing engineering team while remaining hands-on; post-training or fine-tuning experience is a plus.
