In this role, you will design and ship scalable software across edge infrastructure, data pipelines, protocol layers, and developer tooling. You will work on cutting-edge standards like WebMCP, MCP, AEO, and agent-native controls that enable content owners to manage how autonomous AI agents find, parse, and safely execute tasks on their digital properties.

What you'll do

• Design and ship production-ready services that enable customers to evaluate, test, observe, and measure how AI agents read, represent, and interact with their websites and applications.
• Build and maintain support for emerging agent protocols and integrations (MCP, MCP Apps, UCP, MPP, WebMCP).
• Implement fine-grained content controls (access management, licensing, auditing) and agent-native audience/business models (attribution, monetization, and analytics).
• Write clean, secure, well-tested code, advocate for end-user privacy, and help maintain high system reliability, performance, and documentation.
• Partner with software engineers, researchers, product managers, design engineers, and cross-Cloudflare stakeholders to take capabilities from concept to production.

Desirable Skills, Knowledge, and Experience

• Strong software engineering and distributed systems fundamentals.
• Experience building and operating reliable, high-throughput production services.
• Solid understanding of HTTP, APIs, proxies, caching, web security, and web performance.
• Hands-on experience or deep interest in AI agents, tool calling, Model Context Protocol (MCP), or agent harnesses.
• 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).
• Hands-on experience with search, Answer Engine Optimization (AEO), web crawling, or RAG platform engineering.
• Open-source contributions to agent frameworks, protocols, web standards, browser engines, or distributed systems projects.
• Past experience contributing to a major web framework, proxy, CDN infrastructure, or bare-metal backend cloud provider.
• Proven track record of debugging and resolving network-level and application-level performance bottlenecks.
• Understanding of cryptographic concepts (public-key encryption, digital signatures, hash functions) or privacy-preserving web protocols.

Compensation

Compensation may be adjusted depending on work location.

• For Portugal based hires: Estimated annual salary is between €54,000 - €75,000.
• The final offer will be inclusive of time exemption, in alignment with the applicable law and collective bargaining agreements.

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.
