Ready to join a mission that matters? The future of cybersecurity starts with you.

As a Senior(+) Engineer (typically equivalent to Staff or Sr Staff titles in other companies), you’ll join this Core Platform Team with bottom‑up visibility and ownership over a fast‑expanding codebase aimed at AI‑based Detection & Response. You’ll work on deploying core services to new clouds, modularizing reusable components, improving core libraries, frameworks, observability tooling (tracing, profiling, alerting, SLOs, etc.), and reducing manual toil through automation.

Recently the group introduced adaptive concurrency to our core Kafka library for flow control to protect database performance. In overarching terms, you’ll build and maintain the next‑generation infrastructure and security platform for Crowd Strike, including an application and service delivery platform, massively scalable distributed data storage and replication systems, and a cutting‑edge search and distributed graph system.

  Golang, Java, Scala, Kotlin, Python, Node.js.
• Degree in Computer Science (or commensurate experience in data structures, algorithms, distributed systems).
• The ability to scale backend systems – sharding, partitioning, scaling horizontally are second nature to you.
• The desire to ship code and the love of seeing your bits run in production.
• Deep understanding of distributed systems and scalability challenges.
• Deep understanding of multi‑threading, concurrency, and parallel processing technologies.
• Team player skills – we embrace collaborating as a team as much as possible.
• A thorough understanding of engineering best practices from…
