Founding AI Systems Engineer (USA Only - 100% Remote) at Close

This role is for a mid-to-senior full-stack engineer who understands B2B business logic and growth marketing. You should have a background in building internal data tools and enough comfort with Python and TypeScript to automate complex sales workflows using AI. **What makes it worth a look...** The $140k–$210k salary comes with a 6% 401k match, 5 weeks of PTO, and a unique 1-month sabbatical. It is a rare chance to be a "founding" engineer at a profitable, bootstrapped company where your work directly shapes the company's internal $50m operations. **You might be a good fit if you...** * Have experience building lead scoring models or Slack-based business agents. * Can navigate a GTM stack including Segment, Customer.io, and data warehouses. * Prefer writing code that solves immediate business bottlenecks over theoretical infrastructure. * Want a remote US role that offers a yearly international team retreat.
