Staff Site Reliability Engineer, Storage Infrastructure (Cache)

Company Description

Twitter developed and continually improves a large-scale storage platform. SREs ensure availability of the environment, with a watchful eye on security, capacity and performance. This group writes software to improve service reliability and manage platform growth. Our tools and services reduce operational overhead and maximize performance.

The Position

As a Site Reliability Engineer (SRE) in Twitter’s Storage Infrastructure team, you will work to improve the reliability and performance of the next generation of distributed systems and containerized deployments. This team ensures the availability of in-memory data services (including Redis and Memcached), and caching content from foundation storage platforms. You will partner with product engineering teams to design, build, operate, and automate distributed storage services at the heart of Twitter’s infrastructure used by millions of people.

We are looking for software engineers that are passionate about reliability, performance, and efficiency, and that have experience building tools, services, and automation to manage and improve production services.

This team has some exciting challenges approaching. Services need to adopt IPv6, transition into Kubernetes, and reimagine elasticity. Opportunities exist for team members to influence how Twitter leverages future caching infrastructure. Work directly with most Twitter engineering teams to improve their caching services interactions.
