Founding Engineer
Ploy
About Ploy Ploy is an agentic marketing platform that turns your website into your company's main growth engine. We deploy swarms of marketing and web design agents that monitor your site and proactively launch campaigns, content, and optimizations — giving companies the on‑demand infrastructure of a growth team. Ploy is founded by Bryant Chou, the co‑founder and former CTO of Webflow, where he spent 12+ years building the core product, CMS, and hosting that now power ~1.5% of the internet. We're a small, senior team based in San Francisco and backed by Y Combinator and other Tier 1 investors. What you'll work on 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. Who we're looking for You've built 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. If you don't match this exactly but think you'd be great here, apply anyway. We read everything. #J-18808-Ljbffr Ploy
