Description
About Us
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.
As a Senior Software Engineer on the team, you will build the foundational services that enable the world’s largest organisations to run on Cloudflare. You will be responsible for the APIs, UIs, internal tooling, and admin platforms that help manage complex enterprise logic at scale.
More specifically, there will be a heavy focus on scaling and extending Organisations - the new abstraction for our largest customers and partners to manage Cloudflare. While this is a full-stack role, our roadmap for the coming year is weighted toward backend architecture and systems design.
You will spend your time helping design our data models, architecting high-performance services in Go, optimising our PostgreSQL layer, and ensuring our services are resilient within our Kubernetes ecosystem.
You won't just ship features; you will also own the "operational excellence" of your services. You’ll use tools like Jaeger, Sentry, and Kibana to troubleshoot complex distributed traces and ensure our platform remains highly available for our external and internal customers.
You will also rapidly expand your domain knowledge and ability to deliver change through AI tooling. Cloudflare is ramping up its support and infrastructure for AI development tools like OpenCode.
Core Technologies
- Backend: Go, PostgreSQL, Redis, PHP
- Infrastructure: Kubernetes, Docker, Kafka
- Frontend: React, TypeScript
- Observability: Kibana, Elasticsearch, Jaeger, Sentry
Examples of desirable skills, knowledge, and experience
- Senior-Level Backend Expertise: 5+ years of experience building and scaling production-grade applications.
- Systems Architecture: Proven experience designing distributed systems that are scalable, maintainable, and fault-tolerant.
- Pragmatic Full Stack Ability: While your work will be weighted toward the backend, you are comfortable navigating a React/TypeScript codebase to build or improve UI components.
- Agentic AI Development: You are excited about exploring and adopting the rapidly advancing AI tooling in your workflows.
- Databases: Experience with SQL, including schema design, query optimisation, and serving globally distributed actors.
- Observability-First Mindset: You don't consider a feature "done" until it's monitored. Experience using distributed tracing (Jaeger), error tracking (Sentry), and log analysis (Kibana/Elasticsearch) to debug production issues.
- Cloud & Containers: Practical experience deploying and managing services in Kubernetes and Docker.
- Operational Ownership: You are comfortable participating in an on-call rotation and feel a sense of pride in maintaining high-uptime services.

What Makes Cloudflare Special?
We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul.
Fundamental to our mission to help build a better Internet is protecting the free and open Internet.
Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organisations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.
Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration.
Since the project, we've provided services to more than 425 local government election websites in 33 states.
1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver.
This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released.
Here’s the deal - we don’t store client IP addresses never, ever.
We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
