About Us

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. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was recognized by the World Economic Forum as a Technology Pioneer and named to Entrepreneur Magazine’s Top Company Cultures list.

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. Come join us!

About the Department

Cloudflare’s Engineering Team builds and runs the software that handles 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.

About the Team

Our team is responsible for building security products and solutions that help our customers filter out unwanted internet traffic. We do so by leveraging the enormous amount of internet traffic we have in deriving deep and meaningful data insights, and by designing and leveraging machine learning models and other techniques that can operate on high volume and velocity of data with high precision, performance and scalability.

About your Role

You are expected to write high-quality data processing code in Go, Python, Lua or other high-performance languages; building and administering alerting and monitoring our production systems; implementing mathematical, machine learning, and statistical models that are capable of detecting patterns on large data sets at very high speeds; analyzing large-scale data sets for business insights; building data access and controls APIs for internal and external customers.

Key Responsibilities:

  • Develop and operationalize highly scalable software that leverage machine learning, statistical analysis, and other rule-based models
  • Derive and obtain data insights and thread intelligence, propose models and implement effective proof-of-concept (POC)
  • Suggest, collect, synthesize, and document functional requirements and effective technical roadmaps
Qualifications
  • Experience in building, tuning, and improving machine learning models;
  • Running predictive models on large data sets; internals and optimization of Clickhouse database cluster; internals and optimization of CatBoost gradient descent library; running and debugging high throughput, low-latency data pipelines;
  • Experience writing high-quality data processing code in Go, Java, Python, Lua or other high-performance languages;
  • Strong data analytical skills, taking initiative in deriving data insights and thread intelligence, and proposing models and solutions that can lead to quick and effective proof-of-concept (POC);
  • Strong systems-level debugging.
Preferred
  • Experience in cyber security
  • Experience in productionizing machine learning models;
  • Familiarity writing and optimizing advanced SQL queries in Clickhouse;
  • Experience with cluster and configuration management systems such as Docker, Kubernetes, and Nginx;
  • Experience in writing RESTful and microservices applications;
  • Good Linux/UNIX systems knowledge

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: We equip politically and artistically important organizations and journalists 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.

Project Athenian: We created 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.

Path Forward Partnership: Since 2016, we have partnered with Path Forward, a nonprofit organization, to create 16-week positions for mid-career professionals who want to get back to the workplace after taking time off to care for a child, parent, or loved one.

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 policy and ensure that no user data is sold to advertisers or used to target consumers.
