Senior Forward Deployed Engineer in London

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.

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

• 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 experienced with modern languages like TypeScript, Rust, and Go.
• You have a “ship‑first” mentality and maintain a high velocity, staying current with modern frameworks, languages, and deployment patterns.
• Broad technical fluency across the entire stack — from frontend performance and backend logic to data/storage and distributed infrastructure.
• You’ve owned mission‑critical services with real‑world users.
• You have integrated AI‑augmented workflows into your daily development cycle to accelerate prototyping and delivery.
• Ability to decompose complex business requirements into scalable, resilient technical architectures.
• Deep experience with at least one major cloud provider (AWS, GCP, or Azure), including an understanding of serverless, networking, and security primitives.
• You are a self‑starter who thrives in “zero‑to‑one” environments.
• Comfortable engaging in high‑stakes technical and strategic discussions with VP‑level stakeholders.

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.
