Senior Software Engineer, Enterprise Readiness

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. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

We realize people do not fit into neat boxes. We are looking for curious and empathetic individuals who are committed to developing themselves and learning new skills, and we are ready to help you do that. We cannot complete our mission without building a diverse and inclusive team. We hire the best people based on an evaluation of their potential and support them throughout their time at Cloudflare.

About The Department

Cloudflare’s Engineering Team builds and runs the software that handles about 10% of HTTP requests on the Internet today. We also build and run the internal tools that builds and runs our software. The Engineering Team is split into two groups: one handles product development and the other handles operations. Product development covers both new features and functionality and scaling our existing software to meet the challenges of a massively growing customer base. The operations team handles one of the world’s largest networks with data centers in 102 cities worldwide.

What you’ll do

As a Senior Software Engineer on the team, you will build the foundational services that enable the world’s largest organizations 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 our

Organizations model

• 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

, optimizing 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.

Which, connected to everything safely possible with MCPs, is enabling engineers to have greater impact, faster than ever.

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. Deep proficiency in a typed language like

Go, PHP

,

Rust

, or

Typescript

for APIs is a plus, but our primary language Go can be learned on the job.

Systems Architecture

Proven experience designing distributed systems that are scalable, maintainable, and fault-tolerant. You understand how to manage state, concurrency, and data consistency.

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 optimization, 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 organizations 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.
