GTM Engineer
Build and own AgentMail's growth data pipelines, outbound engines, lookalike modeling, and PLG experiments as the company's single source of truth for growth. Requires technical scripting in Python/TypeScript/SQL, high agency, and experience with growth motions at PLG companies.
About the job
What You'll Do
- Own the growth data layer end to end: instrument the funnel, enrich every signup, and build the dashboards the company treats as the source of truth.
- Turn our best customers into ten more: lookalike modeling, automated outbound, LinkedIn plays, and surfacing champions and buyers inside companies already using us.
- Run experiments across the PLG engine (content, integrations, backlinks, paid) and double down on what moves signups.
- Connect the stack through APIs, webhooks, and automation so data moves cleanly between PostHog, our CRM, enrichment providers, and outbound tooling.
- Decide what tools we use and what gets kicked to the curb. You own the stack.
- Build AI-powered internal tools.
- Ship systems from prototype through rollout and adoption, then hold your ground. You built it, the team follows it.
What We're Looking For
- A technical foundation: CS, data science, or equivalent. You write real scripts in Python/TypeScript/SQL, wire APIs together, and are dangerous with Claude Code or Codex.
- You've seen a great growth motion up close, or you've been obsessively reverse-engineering how the best PLG companies grow.
- High agency in ambiguity: you call out what's broken, come with an opinion, and fix things without being asked.
- Low ego, high buy-in.
- Organized enough that the systems you build don't rot. Clean data is a discipline, not a feature.
- You want to help invent a market, not just run someone else's process.
Bonus Points
- Hands-on experience with tools like Clay, n8n, enrichment waterfalls, or sending infrastructure.
- PostHog fluency (we live in it).
- You've shipped agentic workflows or internal AI tooling before.
- You've worked at or studied a technical PLG company up close.
