Senior Software Engineer

Treeline is building a comprehensive software stack to transform traditional Managed Service Providers (MSPs) – firms that handle ongoing IT, security, and a majority of software purchasing for small and mid-market businesses – into a software-defined model powered by automation and AI. Valued at more than $150 billion, the MSP market comprises 45,000 providers across the U.S. and Canada, serving the majority of SMB and mid-market enterprises. Founded by Stanford alumni with over a decade of experience in Silicon Valley, Treeline is backed by top VC firms.

We’re a small, highly effective team that values impactful execution, modern tooling, and minimal bureaucracy. We prioritize making Treeline a truly enjoyable, long-term workplace – one where communication is open, politics are absent, and engineers have the autonomy and support to tackle challenging problems.
