Description

DLP's rule-based framework is broken. We asked machines to find problems with rigid rules, then expected humans to investigate the noise - an impossible task. Jazz is the new model. It starts with total coverage from a forensic endpoint agent and uses a powerful Agentic Investigator that learns your business. It delivers clear, pre-investigated answers instead of alerts, and is designed to be run by a single person. Finally, DLP that works. We are looking for a Senior Low-Level Engineer to build the core technology that powers our endpoint intelligence. This role focuses on developing and owning critical capabilities within our Windows and macOS agents, from early research and proof of concept through production deployment. This is an early-stage, high-impact role where engineers take full ownership, move quickly, and shape foundational systems. What You’ll Do: Design and develop core capabilities for our Windows and macOS agents from early research and proof of concept through production deployment. Explore new technical approaches, prototype solutions, and translate ideas into reliable and secure production code. Own features E2E and integrate agent capabilities with backend systems and product workflows. Build performant and reliable components that operate at the OS level and handle complex system interactions. Ensure strong observability, performance, and stability across agent behavior in production environments. Collaborate closely with backend, product, and security teams to deliver capabilities that support real-world security investigations. What We’re Looking For: +4 years hands-on experience with low-level programming in languages such as Go, C, C++, or Swift, with a deep understanding of systems programming. Strong knowledge of operating system internals and system-level development. Experience building endpoint agents, system extensions, or similar low-level software. Experience working with Windows and macOS environments. Experience with reverse engineering and analyzing system behavior. Experience with Rust is an advantage. Demonstrated technical curiosity through projects, CTFs, competitions, or other hands-on technical activities. Ability to work independently, move quickly, and take ownership of complex technical challenges. Why join Jazz? Work on cutting-edge AI + cybersecurity challenges. Architect systems with massive technical depth and scale. High ownership and autonomy in an early-stage environment. Direct impact on product outcomes and engineering decisions. Collaborate with elite engineers and founders who have built large-scale systems before. Our office is located at Sonol Tower, Tel Aviv, next to Carlebach rail station. Requirements null
