The posting

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
