Senior Systems Engineer, AI Gateway

Available Locations: Austin TX or San Francisco CA

About the Role

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. AI Gateway is Cloudflares bet that this layer should exist at the network edge: close to users close to compute and simple enough that a developer can adopt it with one API change.

We are looking for a Senior Systems Engineer to help build that layer. This is a deeply hands-on individual contributor role for someone who can move from a half-formed product idea to a working production-ready system quickly. You will work across the stack from distributed systems and high-throughput APIs to developer-facing workflows dashboards SDKs and docs helping define how developers build and operate AI applications on Cloudflare.

You should be excited by the current pace of the AI ecosystem. Provider APIs change weekly new models appear constantly and developer expectations are rising just as quickly. AI Gateway needs engineers who can build durable infrastructure in that environment without slowing down.

We also believe AI should change how we build software not just what we build. We dogfood AI Gateway Workers AI and Cloudflares broader agent stack heavily. You should be comfortable using AI-native tools agents harnesses and automation to improve your own engineering loop and interested in building the internal tools and context that help a small team ship like a much larger one.

Responsibilities

• Build core AI Gateway systems that handle high-volume inference traffic across providers models and Cloudflares 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 Cloudflares 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.
• 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.

Desirable Skills Knowledge & Experience

• 5 years of experience building and operating production systems ideally in AI infrastructure developer platforms cloud infrastructure edge/proxy systems high-scale APIs or distributed systems.
• Strong systems engineering fundamentals: networking APIs reliability observability data modeling performance and operational tradeoffs.
• Experience designing or scaling distributed systems where latency throughput availability and correctness all matter.
• Ability to work comfortably across the stack from API design and product surfaces to backend services queues storage systems control planes or performance-critical code.
• Strong developer tools taste. You have used and built enough APIs SDKs dashboards CLIs docs and internal platforms to know what makes them delightful or painful.
• Clear technical communication: you can write design docs explain tradeoffs review architecture and align engineers and product partners around a practical path forward.
• A builders bias toward working software. You can prototype quickly ship incrementally and improve systems while they are already in production.
• Operational judgment. You understand that at Cloudflare scale rare bugs are not rare for long and you build systems that are observable resilient and recoverable.
• Comfort using AI-native development workflows and curiosity about how agents tools and automation can improve engineering productivity.

Bonus Points

• Experience building AI/ML infrastructure inference platforms model gateways LLM-powered applications or provider abstraction layers.
• Experience building developer-facing APIs SDKs CLIs dashboards or platform products at scale.
• Hands-on experience with proxy edge gateway routing or traffic management systems.
• Familiarity with the current AI ecosystem: model providers model capabilities agent frameworks inference patterns and the rough edges developers hit in practice.
• Experience with cost controls rate limits caching retries fallbacks evaluation or observability for AI workloads.
• Experience with TypeScript Go Rust or similar systems/backend languages.
• You have built or heavily customized your own agentic development environment: custom agents harnesses tools or workflows that changed how you ship.
• You have built something with AI Gateway Workers AI or a competing product and have opinions about what is missing.
• A track record of writing publicly about developer tools infrastructure systems or AI products you have built.

Were not just a highly ambitious large-scale technology company. Were a highly ambitious large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014 weve equipped more than 2400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work technology already used by Cloudflares enterprise customers--at no cost.

Athenian Project: In 2017 we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free so that their constituents have access to election information and voter registration. Since the project weve provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Heres the deal - we dont store client IP addresses never ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
