The posting

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.

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.
