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.

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

About the Role

The Security Platform team is an infrastructure/developer tools group tasked with building and operating powerful, resilient, and secure infrastructure and systems that enable other engineering teams to deliver products to our customers efficiently and securely. We are responsible for secrets management, internal certificate authorities/PKI, machine and workload identity, and more. We are not a policy, audit, or compliance team, but rather an infrastructure engineering/software development one.

Responsibilities

You’ll build and operate secure and resilient distributed systems for secrets and key management, running across our network that spans more than 310 cities in over 120 countries. Our focus is strengthening/re-architecting internal PKI and machine/workload identity. You’ll run and support the systems we build, both in an operational sense and by helping other internal developers use them. You will participate in the On Call rotation for emergency incident response. You’ll consult on the design and architecture of new systems and products to ensure they are built securely and use our services correctly.

Required skills

Production software development: Experience designing, building, and maintaining production software in Go, C, C++, Rust, or comparable languages. We value systems-oriented engineering experience, not familiarity with a particular language alone.
Production infrastructure ownership: Experience both building and operating critical production services or infrastructure, including debugging failures, recovering service, and improving reliability. Ability to reason about distributed systems and their failure modes.
Linux/UNIX proficiency: Hands-on experience administering and troubleshooting Linux/UNIX systems in production.
Security engineering: Experience developing or operating software or systems designed to provide security capabilities or enforce security boundaries. This can be part of a broader software or infrastructure engineering role; a dedicated security job title is not required.
Applied cryptography: A working understanding of symmetric and asymmetric cryptography and public key infrastructure (PKI), sufficient to make sound implementation choices using established libraries and protocols. Experience designing new cryptographic algorithms is not required.

Bonus/nice-to-have skills

Experience with secrets management, key management, internal certificate authorities/PKI, or machine and workload identity.
Experience managing the lifecycle of keys, certificates, or credentials, including issuance, rotation, expiration, and revocation.
Familiarity with HashiCorp Vault, OpenBao, or similar systems.
Experience with hardware-backed security, such as HSMs, TPMs, or trusted execution environments.
Familiarity with Go, Python, or Salt.
Contributions to open source security, systems software, or distributed systems projects.

You do not need experience with every technology listed above. We welcome candidates with strong software and infrastructure engineering fundamentals and related security experience.

Compensation

Compensation may be adjusted depending on work location.

For California based hires: Estimated annual salary of $194,000 - $266,000
For Colorado based hires: Estimated annual salary of $168,000 - $231,000
For New York based hires: Estimated annual salary of $185,000 - $254,000
For Washington based hires: Estimated annual salary of $185,000 - $254,000
For Washington DC based hires: Estimated annual salary of $185,000 - $254,000
For Canada based hires: Estimated annual salary of $150,000 - $206,000

Applications will be accepted until December 25, 2026.

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.

Sound like something you’d like to be a part of? We’d love to hear from you!
