Nightfall AI

Senior Backend Engineer responsible for building scalable, secure, real-time services and agentic AI systems that power Nightfall’s data loss prevention platform. The role combines distributed systems, search, data infrastructure, observability, and LLM-powered workflow orchestration.

Build the backend and AI platform that powers Nightfall’s real-time data protection at massive scale. You’ll architect reliable services, data infrastructure, and low-latency AI inference systems used to detect sensitive data and prevent exfiltration.

Build and scale machine-learning systems that detect and prevent data leaks in real time. This hands-on role combines model development, LLM and agentic workflow experimentation, production AI infrastructure, and Go-based data-processing services.

Lead the development of Nightfall’s Linux endpoint DLP agent, building kernel-level interception and userspace policy enforcement from the ground up. Own a strategic Linux platform spanning security monitoring, enterprise deployment, reliability, and cross-platform agent architecture.

Build and evolve macOS endpoint agents and system extensions that prevent data exfiltration across sensitive enterprise environments. This role combines OS-level development, endpoint security, and deep debugging of mission-critical software.

Build and evolve Windows endpoint software that prevents sensitive data exfiltration, including agents, drivers, system extensions, and services. This role combines Windows platform expertise with kernel-level debugging and secure software development.

Lead the design and development of Windows endpoint software that prevents data exfiltration, including drivers, system extensions, agents, and services. The role requires deep Windows internals expertise and ownership of complex features from design through delivery.

Lead the design and development of endpoint data-exfiltration prevention software for macOS. This role owns mission-critical endpoint agents, system extensions, and complex features from design through delivery.
