Director, Sales Engineering

Nightfall is the AI-native, unified data loss prevention and insider risk management platform that protects sensitive data across SaaS apps, GenAI tools, email, endpoint devices, and more. Hundreds of customers, spanning AI innovators to top 10 banks, trust Nightfall to detect and stop data exfiltration at scale. Nightfall enables organizations to innovate freely without the risks of losing intellectual property or exposing customer data. Our agentic platform helps security teams regain their time by putting data loss prevention on autopilot. With automatic remediation, security violations can be resolved automatically before they become incidents, and end-users can be automatically trained and coached in the moment to self-heal violations that they introduce.

Nightfall is backed by leading VC firms including Bain Capital Ventures (Enrique Salem - former CEO of Symantec), Venrock (early investors in Cloudflare), WestBridge Capital, Pear VC (early investors in Dropbox and Doordash), and a cadre of cybersecurity leaders including Frederic Kerrest (founder of Okta), Maynard Webb (former COO of eBay), Ryan Carlson (President of Chainguard), Kevin Mandia (founder of Mandiant), and many others.

We're hiring a Director of Sales Engineering to lead our SE team and shape how Nightfall wins technically. You'll lead three SEs covering Enterprise and Commercial deals, and you'll stay hands-on: running demos, building labs and jumping into the deals where you can make the difference.

Enterprises are deploying AI tools and agents faster than their security programs can keep up, and buyers want to see how Nightfall protects their data across people, AI agents, SaaS, email and endpoints. You'll make sure every technical evaluation shows that clearly, and you'll bring what you hear in the field back to our product and engineering teams.

This is a player-coach role. You'll work closely with our CRO on how sales engineering scales as we grow.
