Software Engineer, Agentic Discovery

About Us

Available Locations: Lisbon, or London (Hybrid)

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 products that enable the next era of the Internet: making domains Readable , Discoverable , and Callable for autonomous AI agents.

Here at Cloudflare, agentic discovery is a core part of our vision for the Agentic Internet . As AI agents change how humans and machines find, evaluate, and act on information, businesses need tools to control how they are represented and reached. We build capabilities that enable website owners to prepare their sites for agent interaction, test and observe how agents read their content, establish open interaction standards (like WebMCP and MCP), and create entirely new channels to reach agentic audiences.

We are a cross functional 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 Discovery team to build the core systems, protocols, and customer-facing tools powering agent-web interactions.

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.
