Senior Systems Engineer, AI GatewayActive$194K–$266K

AI inference is becoming core infrastructure. Every serious application will need access to many models, across many providers, with reliability, observability, security, cost control, and routing built in from the start.

What you'll do

• Build core AI Gateway systems that handle high-volume inference traffic: across providers, models, and Cloudflare’s global network.

• Design and implement APIs, routing primitives, observability features,: controls, and developer workflows that make AI Gateway reliable and easy to adopt.

• Work across product and infrastructure boundaries with Workers AI, Agents,: and the broader Developer Platform organization to make Cloudflare’s AI platform feel like one coherent product.

• Turn ambiguous product and technical ideas into prototypes, design docs,: shipped features, and measurable production improvements.

• Improve reliability, performance, cost efficiency, and debuggability for latency-sensitive AI workloads.

• Build the software: and the software that builds the software: agents, tests, harnesses, evaluation loops, operational tools, and internal context that help the team move faster with confidence.

What they're looking for

• Sweat the developer experience. Error messages, SDKs, dashboard flows, docs,: examples, and API details all matter.
• Mentor other engineers through design review, code review, debugging, and: technical leadership without needing people-management authority.
• Bring strong opinions, clear judgment, and a willingness to revise your view: when data, users, or production reality prove otherwise.
