Senior Software Engineer, Agentic Commerce

Cloudflare•San Francisco, CA

21h•Hybrid

About The Position

Cloudflare is hiring a Senior Software Engineer for its Emerging Technologies & Incubation (ETI) Agentic Commerce team, based in Lisbon or London in a hybrid workplace. The team builds infrastructure that enables machine-to-machine commerce and makes web content, services, products, data, and outcomes payable to autonomous agents. Its work spans high-throughput web infrastructure, low-latency transaction processing, usage metering, outcome verification, digital wallets, and emerging agentic payment protocols, while connecting mainstream fiat commerce rails with decentralized protocols. The Senior Software Engineer will act as an expert and technical leader, defining architecture, building core systems, and establishing engineering standards for payments, metering, and monetization across Cloudflare’s network. The role includes shaping product and engineering roadmaps with customers, Product Management, and other Cloudflare teams; writing architectural specifications; improving system resilience, observability, and recovery; leading complex incident responses; reviewing major systems; defining product KPIs; and mentoring engineers 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 or rails, web security, and cryptographic authorization mechanisms.
Demonstrated experience defining product KPIs and translating complex customer and product requirements into architectural roadmaps.
Proven ability to debug complex distributed-system failures spanning multiple teams and systems, with a focus on systemic remediation.
Strong history of technical mentorship, leading incident retrospectives, and driving process improvements within and beyond an immediate team.
Ability to rapidly prototype, evaluate architectural trade-offs, and establish design patterns in an emerging technical domain.
Excellent technical writing and communication skills, including experience drafting RFCs and specifications consumed by multiple engineering organizations.

Nice To Haves

Fluency in Rust, especially async Rust, or TypeScript/JavaScript edge runtimes such as Cloudflare Workers, Durable Objects, or KV at system-architectural scale.
Deep knowledge of emerging agentic payment protocols such as x402, A2P, ACP, UCP, or 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 such as public-key encryption, signatures, and 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.

Responsibilities

Design and build resilient, low-latency systems and core architectures that make web resources payable for autonomous agents using emerging protocols such as x402, WBA, ACP, and UCP.
Write technical specifications (RFCs) and architecture designs for deliverables used by engineers within the team and across other Cloudflare engineering groups.
Work directly with customers and Product Management to clarify requirements, define actionable KPIs, and translate business needs into scalable architectural solutions.
Architect services that reduce code complexity, support recovery from internal and external failures, and improve system health observability.
Lead complex incident responses, retrospectives, and root-cause analyses; drive initiatives to prevent customer escalations and reduce system alerts.
Debug and resolve complex issues spanning multiple teams, services, and protocols, and teach others how to handle similar challenges.
Mentor engineers, improve engineering and interviewing processes, conduct high-impact specification and code reviews, and share knowledge through technical talks and writing.
Shape product and engineering roadmaps in partnership with customers, product managers, and teams across Cloudflare.
Define core product KPIs and establish technical standards for the team and organization.
