About Prelude

Prelude is a small team of security researchers and software developers working to reinvent the way we protect endpoints in a world where threats are complex, emergent, and accelerating. Backed by Sequoia Capital, Insight Partners, and other leading investors, we are building an advanced security solution currently in early-access release. Greater detail about this initiative will be shared as conversations progress.

Role

We are seeking to expand our research and development team with highly technical software engineers. The team is primarily responsible for designing and developing high-performance systems for a greenlit product currently in development. In this role, you will work at the intersection of operating system internals, agent and service development, and endpoint security building resilient and efficient software.

As a core contributor, you will focus on systems programming, high performance endpoint agent development, and service architecture. Expertise in areas such as Windows internals, agent performance optimization, and secure service development will be key to success. This role requires delivering scalable, high-quality software, driving innovation, and collaborating across engineering and research teams to advance our mission.
