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 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 hugely 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.
About the Team
We build the infrastructure that makes the web Payable, powering the future of machine-to-machine commerce.
Here at Cloudflare, agentic commerce is a core part of our vision for the Agentic Internet. As AI agents increasingly navigate, consume, and act on the web, standard payment and authorization models built for humans are breaking down. We build tools that make the new internet payable by giving our users the ability to monetize access to their content, data, services, products, and outcomes across the Internet, regardless of where they are hosted.
Building these capabilities requires solving complex engineering problems across high-throughput web infrastructure, low-latency transaction processing, usage metering, outcome verification, digital wallets, and emerging agentic payment protocols (such as x402, WBA, ACP, and UCP). We bridge mainstream fiat commerce rails with decentralized protocols, enabling micro-payments at Internet scale.
We are a tight-knit group that communicates and collaborates regularly. We celebrate our achievements, support each other when we make mistakes, and hold each other and our work to a high standard.
About the Role
We are looking for a Software Engineer to join our Agentic Commerce team to build the core systems, protocols, and customer-facing tools powering machine-to-machine payments, metering, and monetization.
In this role, you will design and ship scalable software across edge infrastructure, transaction engines, protocol layers, and developer tooling (such as our Monetization Gateway). You will work on cutting-edge standards, cryptographic authentication, and commerce controls that enable businesses to define pricing terms, authenticate agents, verify outcomes, and manage agent-generated revenue streams.
What you’ll do
-
Design and ship production-ready, low-latency services that make web resources Payable for autonomous agents using emerging standards (x402, WBA, ACP, UCP).
-
Build high-precision systems for usage metering, pricing definition, outcome verification, and value attribution tailored for agentic workflows.
-
Build secure protocols and capabilities for authenticating and authorizing buyers, sellers, and autonomous agents across host-agnostic endpoints.
-
Develop capabilities and APIs that give businesses granular visibility, telemetry, and control over agent-generated revenue, billing, and settlement.
-
Build resilient bridges between mainstream fiat commerce rails, digital wallets, and decentralized/cryptographic payment protocols for Internet-scale micropayments.
-
Write clean, secure, well-tested code, maintain strict accounting/financial precision, and advocate for high reliability, security, and low-latency performance.
-
Partner with software engineers, researchers, product managers, design engineers, and cross-Cloudflare stakeholders to take capabilities from concept to production.
Examples of Desirable Skills, Knowledge, and Experience
-
Strong software engineering and distributed systems fundamentals.
-
Experience building and operating reliable, high-throughput, low-latency production services.
-
Solid understanding of HTTP, APIs, payment protocols/rails, web security, or cryptographic authorization.
-
Hands-on experience or deep interest in payment systems, usage metering, billing engines, digital wallets, or machine-to-machine interaction protocols.
-
Ability to rapidly prototype, evaluate architectural trade-offs, and ship solutions in a fast-moving, emerging technical domain.
-
Strong written and verbal communication skills.
Bonus Points
-
Fluency in Rust (with a big plus for experience in async Rust) or TypeScript/JavaScript edge runtimes (e.g., Cloudflare Workers, Durable Objects, KV).
-
Experience with emerging agentic payment protocols (x402, A2P, ACP, UCP, Web Bot Auth) or digital wallet architectures.
-
Experience building high-precision event metering pipelines, usage-based billing engines, outcome verification systems, or revenue attribution tools.
-
Experience with smart contract bridges, cryptography (public-key encryption, signatures, hashes), or hybrid fiat/crypto payment infrastructure.
-
Open-source contributions to payment systems, agent protocols, web standards, or distributed systems projects.
-
Proven track record of debugging and resolving performance, concurrency, or transactional correctness bottlenecks.

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.
