Senior Software Engineer, Backend

Common Room is the AI GTM Platform that empowers your teams with AI agents built on complete buyer intelligence. We unify every signal across the full buyer journey into one continuously-updated, person-level view—so your team knows exactly who to target and why, what to say, and when to reach out.

GTM teams are drowning in tool sprawl, fragmented data, and AI that doesn't deliver. Common Room replaces your disconnected stack with one platform built for scale and complexity. We bring together data, orchestration, and execution in one system built for orgs of 75-1000+.

We've raised over $50 million from top-tier investors including Greylock, Index, and Madrona, and we're backed by 25+ operators from companies like Figma, Stripe, Airtable, Slack, Notion, Loom, and more.
