Founding Engineer

Ploy · San Francisco, CA · 3 wk ago
On-siteEngineering$150k–$250k/yrFull-time

About the role

The surface area is wide. You'll touch some mix of:

  • Multi-agent systems that plan, execute, and learn from websites and growth channels in production — orchestration, memory, evals, and everything it takes to keep them reliable.
  • The infrastructure that lets those agents make changes to live sites safely at scale — previews, diffs, rollbacks, performance guardrails.
  • The primitives and interfaces customers use to direct the agents themselves.
  • The feedback loops that make the product get smarter about a customer's business the longer it runs.

Responsibilities

You'll build something from 0 to 1 and thrive in ambiguity. You're comfortable going deep on any part of the stack — frontend, backend, infra, or ML/agent systems — and have strong taste in at least one. You've worked with LLMs in production, or you're hungry to. You make good decisions fast with incomplete information, and you're honest when something isn't working. You want to work in person in San Francisco, most days, with a small team that moves quickly.

  • You're comfortable going deep on any part of the stack — frontend, backend, infra, or ML/agent systems — and have strong taste in at least one.
