About Nooks

AI agents that dial, sequence, follow up, and prep deals alongside your reps. 1,800+ revenue teams run outbound, inbound, and deal management on Nooks. Backed by Kleiner Perkins.

About the role

Nooks is the Agent Workspace for Sales, where reps and AI agents execute and decide next moves together across 1M+ interactions per day. As our second security engineer, you'll help secure a fast-growing, AI-native platform and the customer data that flows through it — across a rapidly expanding set of product surfaces. This is a foundational, high-ownership role: you'll shape our security program from the ground up, including the novel challenge of securing AI agents and how they're used within organizations.

What they're looking for

  • 3+ years of hands-on information security experience
  • Experience at a startup or early-stage company, comfort with ambiguity, autonomy, and high ownership
  • Strong fundamentals in application and/or cloud security (AWS/GCP)
  • Pragmatic judgment — able to prioritize risk and do more with less
  • Clear communication and a collaborative, low-ego style

Nooks is an applied AI lab building the Agent Workspace for GTM. We design AI agents that operate across the full sales action set, from account strategy to prospect research and outreach .

Our mission is to 10x every seller by automating the busywork so they can focus on what humans do best: closing deals.

Today, over 1,500 customers run on Nooks, including Notion, HubSpot, Cursor, and Rippling. We’ve raised $70M+ from top VCs like Kleiner Perkins, which made its first sales-tech investment in over a decade with us. Since then, we’ve tripled ARR each year for 3 years running and grown a high-caliber team turning the art of sales into a scalable science.
