Full Job Description
About Nightfall: 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. About the role: This is not a purely organizational role. We are looking for a player-coach - someone who leads the team and writes production code. You will own Nightfall's entire endpoint engineering effort across Mac, Windows, and QA today, while personally driving the architecture and early implementation of our Linux platform from the ground up. The ideal candidate has spent years in the trenches of systems and kernel-level development and now wants to multiply their impact through leadership - without stepping away from the code. You will set technical direction, mentor senior engineers, drive delivery at startup pace, and remain a hands-on contributor to the most complex and strategic parts of the codebase.
