About The Position

Substack is building a new economic engine for culture, giving the brightest, most interesting, and most creative people on the internet the power of their own publishing platform. Substack empowers independent writers, artists, videographers, podcasters, and creators of all types to create, share, and make a living off their work through subscriptions, while offering them creative freedom, ownership, and a direct connection to their audiences. We're looking for an IT Systems Administrator to own our internal IT operations end to end. This is a hands-on individual contributor role for someone who thrives in a fast-moving environment, takes pride in running a tight, well-organized IT function, and knows how to build systems that scale. You'll be the go-to person for everything from onboarding new hires to managing our SaaS tool stack and supporting our path to SOC 2 compliance.

Requirements

3–5 years of experience in a corporate IT or systems administration role, ideally at a tech company

Familiarity with SOC 2 requirements and ideally experience working in or toward a SOC 2 environment
Strong communicator who can work cross-functionally with operations, engineering, and external vendors
Organized and process-oriented — you document what you build and build for repeatability

Experience with compliance platforms like Vanta or Drata is a plus
