At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Intern...

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution ...

Cloudflare’s engineering teams build and maintain the systems and products that power our global platform. A global platform which is within approximately 50 milliseconds of about 95% of the Internet connected population, serving on average, over 46 million HTTP requests per second.

Cloudflare engineering delivers code to production at a tremendous pace, and depends on automated testing to do so without incidents. The SLO team builds and runs the internal platform and tooling that empowers other engineering teams to set up Service Level Indicators (SLIs) and effectively measure their Service Level Objectives (SLOs). This enables all engineering teams to effectively measure their service and feature reliability that verify the interactions between systems and products in production at huge scale.
We are looking for a highly motivated software engineer to join our Production Platform Organization. You will build the infrastructure necessary to collect, store, and make reliability data easily accessible for monitoring needs. You’ll need to communicate effectively and proactively with engineers across the company to deeply understand the behaviors of our systems and refine their reliability objectives. You will also work closely with Product Managers and Product Site Reliability Engineers on quality of service measurements for enterprise customers. 
Build the Platform: Create and maintain production reliability testing infrastructure and availability reporting.
Define Reliability Metrics: Measure uptime metrics like correctness, availability, and latency SLIs/SLOs. Develop, document, and execute SLI/SLO plans to verify systems continue to operate as expected.
Collaborate Cross-Functionally: Collaborate with engineering teams to understand how their systems function and interact with other Cloudflare systems in production at a huge scale. 
Communicate & Improve: Provide clear and concise feedback to engineering and product teams as an excellent communicator. Help drive continued improvements in the software development and reliability measurement processes.

Experience: Proven track record as a software engineer or similar role with a deep understanding of developing and maintaining distributed systems.
System Design: Experience designing, implementing, and maintaining secure and highly-available distributed systems.
Programming Languages: Programming experience with one of the following languages: Go, Rust, or Python.
Reliability Metrics: Deep understanding and hands-on experience measuring uptime metrics like correctness, availability, and latency using SLOs/SLIs.
Experience working with Clickhouse, Prometheus, GraphQL, and Postgres.
Experience working with data pipelines with a focus on reliability and scale.
Experience working with synthetic traffic & load testing tools. 
Experience developing reliable, extensible platforms that other engineers can trust and leverage.
