## Description

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.

Responsibilities:

- 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.

Requirements:

- 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.

Nice to Have:

- 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: For Portugal based hires: Estimated annual salary is between €54,000 - €75,000.
