## Description

This role is part of Datadog’s Security Agent team, which powers critical security capabilities across Workload Protection, Vulnerability Management, Cloud Security products, and other emerging security offerings.

What You'll Do:

 * Lead the architecture and development of security agent capabilities that power runtime threat detection and workload protection across Datadog Security products.
 * Design and build reusable eBPF-based monitoring functionality for process, file, and network visibility within Linux environments.
 * Drive end-to-end delivery of new features, from technical strategy and design through implementation, testing, and rollout.
 * Establish and evolve testing methodologies that improve platform coverage, detection quality, reliability, and performance.
 * Partner with product, security, infrastructure, and engineering teams to deliver shared platform capabilities used across multiple Datadog products.
 * Provide technical leadership by influencing engineering direction, mentoring peers, and helping resolve complex cross-functional challenges.
