About Treeline

Treeline is building the Modern IT Operating System — a software‑ and AI‑native foundation that redefines how IT, security, and compliance are delivered. Rather than layering AI on top of decades‑old workflows, we rebuilt the MSP operating model from the ground up, with software as the foundation. Our AI‑enhanced 24/7 help desk delivers 80% faster response times and a 95% reduction in error rates versus traditional industry standard.

We operate in a $200B+ MSP market where 40,000+ providers still run on manual coordination and reactive ticketing. Treeline replaces that with a centralized software architecture — automating routine operations while elevating human experts to focus on architecture, risk, and strategy. We serve growth‑stage companies, with deep strength in regulated verticals (SOC 2, HIPAA, CMMC).

Through a combination of organic and inorganic expansion strategy, Treeline is growing fast. We’re backed by a16z ($25 M Series A) and have built a team with deep experience at the intersection of software and services, with a team of IT / security services industry‑veterans (e.g., Evergreen, Lyra) and top university graduates (Stanford, Harvard, Berkeley).

As our Finance Operations Associate, you’ll own the accounts payable engine for Treeline — from vendor onboarding through payment, reconciliation, and month‑end close. This is a high‑ownership, early finance hire: you’ll get direct exposure to AI‑native finance operations (we’ll teach you the stack), a clear path to grow as the function and the company scale, and a front‑row seat to a fast‑moving, multi‑entity rollup.

If you’re detail‑obsessed, dependable, and eager to build, there’s room to make the role your own and grow in the company.
