About the Department

Emerging Technologies & Incubation (ETI) is where new and bold products are built and released within Cloudflare. Rather than being constrained by the structures which make Cloudflare a massively successful business, we are able to leverage them to deliver entirely new tools and products to our customers. Cloudflare’s edge and network make it possible to solve problems at massive scale and efficiency which would be impossible for almost any other organization.

What you'll do

We announced Cloudflare Workers in 2017  — since then it’s played a key role in Cloudflare’s strategy for entering the developer platform market. Until the launch of Workers, as Cloudflare was ramping up its capabilities in the performance and security spaces, it became clear that developers needed more ways to control the edge than rules engines could support. Workers has allowed Cloudflare to add programmability to the edge such that developers could have access to writing logic on the edge in their preferred way — through code. Over the past few years, Workers has grown from a simple functions-as-a-service option into a fully blown full-stack platform. With any application, however, in addition to serverless compute, you need to be able to manage state. In 2022, Cloudflare released D1 — built on Durable Objects, D1 is Cloudflare’s first serverless database.  In this role, you’ll be helping define and building the future of D1 to enable developers to build full stack applications.

  • Experience operating high volume Software-as-a-Service (SaaS) applications.
  • Experience designing and building library and REST APIs
  • A solid understanding of computer science fundamentals including data structures, algorithms, and object-oriented or functional design.

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.

Athenian Project: 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.

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.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
