Cloudflare's Emerging Technologies & Incubation (ETI) team is building infrastructure to make the web payable for autonomous agents. This Senior Software Engineer role focuses on agentic commerce—solving the problem that as AI agents increasingly navigate and act on the web, traditional payment and authorization models built for humans are breaking down.
You will design and build resilient, low-latency systems powering machine-to-machine payments, metering, and monetization across Cloudflare's network. The role requires architecting services that handle high-throughput transaction processing, usage metering, outcome verification, digital wallets, and emerging agentic payment protocols (x402, WBA, ACP, UCP). You'll bridge mainstream fiat commerce with decentralized protocols to enable micropayments at Internet scale.
Key responsibilities include:
- Designing and building core architectures for payable web resources using emerging protocols
- Writing technical specifications (RFCs) and architecture designs for internal and cross-team consumption
- Meeting directly with customers and product management to clarify requirements and translate business needs into scalable solutions
- Architecting services that reduce complexity, ensure failure recovery, and improve system observability
- Leading complex incident responses, retrospectives, and root-cause analyses
- Debugging high-complexity issues spanning multiple teams and services
- Mentoring engineers, improving processes, conducting code reviews, and sharing knowledge
You will be a technical leader who shapes product and engineering roadmaps, establishes technical standards, and elevates the collective engineering practice across the organization.
REQUIREMENTS:
- Deep software engineering and distributed systems expertise with a track record of architecting, building, and operating high-throughput, low-latency production services
- Broad experience with HTTP, API design, payment protocols/rails, web security, and cryptographic authorization mechanisms
- Demonstrated experience defining product KPIs and translating complex customer and product requirements into clear architectural roadmaps
- Proven track record of debugging complex distributed system failures spanning multiple teams and systems, with focus on systemic remediation
- Strong history of technical mentorship, leading incident retrospectives, and driving process improvements
- Ability to rapidly prototype, evaluate deep architectural trade-offs, and establish design patterns in emerging technical domains
- Excellent technical writing and communication skills, with experience drafting RFCs and specifications
BONUS SKILLS:
- Fluency in Rust (especially async Rust) or TypeScript/JavaScript edge runtimes (Cloudflare Workers, Durable Objects, KV) at system-architectural scale
- Deep knowledge of emerging agentic payment protocols (x402, A2P, ACP, UCP, Web Bot Auth) or digital wallet architectures
- Experience architecting 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
- Active contributions to open-source payment systems, agent protocols, web standards, or distributed systems projects
- Experience training interviewers, closing candidates, or guiding company-wide technical standards
