The role
You would join our GTM Engineering team, where your closest teammates would be engineers and people from product, marketing and sales.
Our job is to automate the repetitive, mechanical work in sales, marketing and customer success, so those teams spend their time on the things only a human can do: closing deals, nurturing prospects,



and building the relationships that turn into upsells. We do that through experimentation, scrappy by design: find the shortest path to something that works, put it in front of people who will use it, learn and keep going.
In practice:
- Find where the most expensive friction is and build the thing that removes it , usually before the person drowning in it has to ask for help.
- Build it end-to-end, mostly on the backend: integrations with the tools our teams already use, data pipelines, LLM-powered workflows, and whatever interface makes it usable.
- Be measured on the outcome : leads, meetings booked, revenue generated.

A few things stand out about this role. Very few engineers get to draw a straight line from something they built to money the company made. The feedback loop is short: you ship on Tuesday, someone is using it on Wednesday, by Friday you know whether it worked. And you’ll work on AI systems in pro
