System Administrator; Revenue Tools

About Antithesis

We’re on a mission to redefine how modern distributed systems are tested and released. Our platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility. Our platform doesn’t just assure system correctness and reliability, it exists because developers need something better. If you’ve ever experienced the pain of a production outage, had a bad week on-call, or had a release delayed by weeks because of one killer bug – you’ll understand exactly why we’re doing what we do.

If you're passionate about developer-first products, system resilience, and correctness, we’d love to talk.

We’re hiring a Senior Manager–level System Administrator to manage, optimize, and scale our full Go-To-Market (GTM) systems stack. You’ll be the primary owner of Salesforce and the connective tissue across our revenue tools — Clari, Outreach, Zoom Info, Clay, Gong, and others — ensuring data quality, system reliability, automation, and seamless workflows that allow our teams to move fast and scale deliberately.

This is a high-impact, hands-on role for someone who loves making systems work elegantly, enjoys partnering closely with Sales, Customer Success, and Marketing, and wants to build the operational backbone of a fast-growing startup.
