Role
Who you are
- 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
Desirable
- 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
What the job involves
- 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
Our take
Cloudflare is a multi-service global network that provides web security and infrastructure, DDoS mitigation services, and a content delivery network. Founded in 2009, Cloudflare has risen to become an industry giant, with over 25 million global internet properties on its network.
Cloudflare has been responsible for a number of admirable initiatives, offering free web protection to human rights groups, journalists, artists, and US election websites. This goes some way to counteracting the flak Cloudflare has received in some circles for the controversial groups and users who use its services. This chequered history, however, has not affected its over 80% market share in the content delivery network field.
This is perhaps in part because it has proven sharp at staying abreast of the rapidly morphing tech and digital space and customer demands. For example, Cloudflare is shifting to 100% renewable energy usage to create a zero-emissions internet, and in 2020 released a feature that would help users navigate data privacy regulations by selecting where their data is stored.
And impressive third-quarter 2025 results show strong momentum, with revenue rising to $562 million from $430 million a year earlier. The company also raised its full-year guidance, underscoring confidence in continued growth. As demand for secure, cloud-based infrastructure keeps growing, Cloudflare's expanding platform and improving efficiency leave it well positioned to capture further gains in a rapidly growing market.
