Nightfall AI jobs

Backend Software Engineer role at Nightfall AI, a data loss prevention and insider risk management platform. The role involves architecting scalable microservices, authentication systems, and real-time data processing pipelines using technologies like Kafka and distributed databases. Requires 5+ years of systems programming experience (Python, Go, Java, C++), expertise in large-scale distributed systems, and data processing pipeline development. Based in Bengaluru.

Lead Product Designer at Nightfall AI is a senior UX design role responsible for designing intuitive experiences across DLP and insider risk management products. Requires 6+ years of hands-on UX design, strong AI tool proficiency (Cursor, Claude Code), design system development, and portfolio demonstrating interaction and visual design. Located in Bengaluru, India, with remote capability.

Nightfall is hiring a VP/Senior Director of Endpoint Engineering to lead and individually contribute to the endpoint agent platform protecting data across Mac, Windows, and Linux. You'll own the full technical strategy and implementation of endpoint security agents, personally writing production systems code while managing a team of 10+ senior engineers across three platforms. Required: 10+ years in systems/endpoint engineering with kernel-level expertise (macOS Endpoint Security framework, Windows WDF/WDM drivers, or Linux eBPF), 5+ years leading teams of 8+, and deep C/C++ skills—this is a hands-on player-coach role where you code alongside the team, not a distance-management position. The ideal candidate has shipped production agents or endpoint security tools, debugged kernel-level issues, and hired strong engineering teams. Nightfall is a well-funded ($100M+ Series B) AI-native DLP platform backed by Bain Capital Ventures and security luminaries like Kevin Mandia and Frederic Kerrest, protecting hundreds of enterprises from data exfiltration across SaaS and GenAI; the deal-breaker is this requires simultaneous hands-on systems coding and full P&L responsibility for a multi-platform team ramping up Linux development from scratch.

Nightfall, an AI-native data loss prevention platform trusted by hundreds of customers including top banks, is hiring a seasoned Endpoint Engineer to lead the expansion of its Linux agent capabilities from the ground up. You'll design and build production-grade DLP agents covering kernel-level event interception, userspace policy enforcement, and enterprise deployment across Linux distributions. The role requires 5+ years of systems/endpoint engineering experience with deep expertise in C/C++, Linux kernel subsystems (particularly eBPF, LSM hooks, fanotify), kernel-level debugging tools, and enterprise Linux deployments—ideally with prior DLP, EDR, or endpoint security product experience. Nightfall is well-funded by top-tier VCs (Bain Capital Ventures, Venrock, Pear VC) and counts cybersecurity leaders like Frederic Kerrest (Okta founder) and Kevin Mandia (Mandiant founder) among its backers. This is a ground-level opportunity to own a strategic new platform, collaborating closely with existing Mac and Windows teams to align cross-platform architecture. Compensation includes base salary (determined by experience and performance), bonus, benefits, and stock options.
