Controller

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 vs. 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 ($25M Series A) and we’ve 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 Controller, you'll be the operational backbone of Treeline's finance function — running the day-to-day engine (accounts payable, corporate spend, reconciliations, and month-end close) while building the systems that let it scale. This is a mission-critical, foundational hire: you'll bring existing finops experience and pair it with a modern, AI-native tool stack to turn manual work into repeatable processes. You'll get a front-row seat to a fast-moving, multi-entity rollup and a clear path to grow with the function as the company scales. If you’re detail-obsessed, dependable and hungry to build the systems behind a scaling finance org, this role has room to grow with the company as much as you can.

• Audit & Tax: Own the external audit and tax relationships end-to-end — serving as the point of contact for auditors and tax preparers. Coordinate federal and multi-state income, franchise, and sales-and-use tax filings across all entities and manage 1099 and information-return cycles
