At Cloudflare, we have our eyes set on an ambitious goal: to help build a better Internet. Today the company runs one of the world’s largest networks that powers trillions of requests per month. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare have all web traffic routed through its intelligent global network, which gets smarter with every request.

About The Team

Cloudflare’s Technical Operations team is responsible for ensuring the reliability, observability, and resilience of the worldwide platform. Data Storage is a critical component of our platform functionality, which encompasses traditional relational databases (primarily PostgreSQL), Key-Value stores like Redis and (our very own) Quicksilver, and distributed filesystem technologies. As we grow and scale, our portfolio of data storage options will need to grow with us.


We’re looking to establish a team of engineers who will be dedicated to databases and storage at Cloudflare. This team will encompass the full lifecycle of provisioning, monitoring, tuning, and scaling storage solutions. This team will work closely with both SRE and Engineering to provide a highly-automated, highly available and extremely resilient data platform that scales with us.

Main requirements

  • Experience as a professional programmer with operational ownership of the software you’ve written.
  • Direct experience shipping, supporting, and managing distributed systems with demanding consumers.
  • Expertise in operating/administering a traditional relational database system, preferably PostgreSQL
  • Experience writing, debugging, and tuning SQL.
  • Experience in managing distributed storage systems such as Ceph and HDFS.
  • Experience developing software in Go, Python or C/C++
  • Formal computer science background (BS/MS in Computer Science or equivalent)
  • Experience with alerting and monitoring tools such as Prometheus, Grafana, and Kibana
  • Experience with configuration management software, preferably Salt.

Nice to have

  • Interest in newer database technologies like CockroachDB
  • Experience with stream processing technologies
  • Experience with non-relational data stores such as time-series databases (ex. OpenTSDB), key-value stores (ex. Redis), columnar databases (ex. ClickHouse), and full-text search engines (ex. ElasticSearch)
  • Experience with data warehousing tools and patterns
