Senior Forward Deployed Engineer

About Us

At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

About the Role

As an FDE, you'll work as a hands-on, consultative build partner to a portfolio of Cloudflare's most strategic customers — companies building complex, ambitious applications on our developer platform. You'll work shoulder-to-shoulder with their engineering teams to shape architecture, prototype alongside them, review code, and unblock the hard technical problems that stand between them and production — so they can build faster and scale further on Cloudflare.

This is a one-to-many motion. Rather than embedding full-time with a single account, you'll work in parallel, bringing patterns, reference implementations, lessons learned from across your portfolio to every customer you work with. Customers come to us building on the developer platform, but when we engage we support the full breadth of the Cloudflare platform.

You operate as a technical force multiplier — helping customers ship, raising the quality of what they build, and surfacing real-world product insights back to Cloudflare's Product and Engineering teams.

What You'll Do

• Act as the hands-on technical build partner across a portfolio of strategic customers building on the Cloudflare platform, driving each engagement forward from idea to launch.

• Shape scalable, resilient architectures on Cloudflare and guide customers on the design decisions that matter — before they become bottlenecks.

• Hands-on development alongside customer teams to prototype, configure, and build reference implementations that demonstrate the right way to solve a problem on Cloudflare.

• Review customer code and share the best practices that raise the quality, performance, and security of what they build.

• Diagnose and resolve hard technical problems across the stack, removing the blockers between customers and a successful launch.

• Write reference code, samples, and technical guidance that customers can learn from, build on, and reuse.

• Support the full breadth of the Cloudflare platform when engaged — from Workers, storage (KV, R2, D1), and Durable Objects to AI (Workers AI, AI Gateway, Vectorize), security, networking, and observability.

• Join Customer Engineering rituals — design reviews, planning sessions, and technical working sessions.

• Surface real-world edge cases, friction, and product gaps directly to Cloudflare's Product and Engineering teams to shape the product roadmap.

• Establish and maintain trusted technical relationships with customer engineers and technical leaders (Staff+ engineers, Directors, and VPs).

• Identify opportunities to accelerate the adoption of Cloudflare services, unlocking new capabilities across each customer's tech stack.

Desirable Skills, Knowledge, and Experience

• Proven Engineering Pedigree & Customer-Facing Experience: 7+ years of professional software engineering experience, including time in a customer-facing engineering role — such as forward deployed, solutions or sales engineering, professional services, or developer relations — where you worked hands-on with external engineering teams. You are a builder at heart, with a track record of delivering production-grade systems, not just advising on them.

• Languages: You are experienced with modern languages like TypeScript, Rust, and Go.

• Active Practitioner: You have a "ship-first" mentality and maintain a high velocity, staying current with modern frameworks, languages, and deployment patterns.

• Full-Stack Architectural Depth: Broad technical fluency across the entire stack — from frontend performance and backend logic to data/storage and distributed infrastructure.

• Production Maturity: You've owned mission-critical services with real-world users. You understand production rigor, the urgency of incident response, and the architectural discipline required to run highly available systems.

• AI-Native Development: You have integrated AI-augmented workflows (e.g., Windsurf, OpenCode) into your daily development cycle to accelerate prototyping and delivery.

• Systems Design & Strategic Thinking: Ability to decompose complex business requirements into scalable, resilient technical architectures. You can visualize the "big picture" without losing sight of the implementation details.

• Cloud Ecosystem Fluency: Deep experience with at least one major cloud provider (AWS, GCP, or Azure), including an understanding of serverless, networking, and security primitives.

• High Agency & Navigating Ambiguity: You are a self-starter who thrives in "zero-to-one" environments. You don't wait for a ticket; you identify the problem and own the solution end-to-end.

• Executive Presence: Comfortable engaging in high-stakes technical and strategic discussions with VP-level stakeholders, with the ability to translate complex engineering trade-offs into business impact.

Bonus Points

• Direct experience building on Cloudflare Workers or the broader Cloudflare Developer Platform.

• A visible public profile, including open-source contributions, technical blogging, or speaking engagements at industry conferences.

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re 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, we've equipped more than 2,400 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 Cloudflare’s 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, we've 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. Here’s the deal - we don’t 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.
