The posting

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.

COMPENSATION & BENEFITS

Salary range: $200,000 to $300,000 USD annually. Visa sponsorship is not available.

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.
