About the Role:

As a Senior+ contributor, you'll join this Core Platform Team with bottom-up ownership of our codebase and a far-reaching edict for service resiliency, with several key feature additions and critical re-architecture initiatives underway (improvements to core libraries and platform services, observability tooling (tracing, profiling, alerting, SLOs etc), and automation to reduce manual toil).

Recently we introduced adaptive concurrency to our core kafka library which implements flow control to protect database performance and are presently making large-scale automations around how we build new clouds. In terms of overarching goals, we’re building the next-generation infrastructure and security platform for CrowdStrike which include an application and service delivery platform, massively scalable distributed data storage and replication systems, and a cutting-edge search and distributed graph system.
