Principal Engineer - GTM Data Platform

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. Available Locations: Austin, Texas About the role Created in January 2025, our centralized Developer Go-to-Market (GTM) organization functions as a "speedboat" to maintain focus, control direction, and iterate quickly. Our mission is to build long-term relationships with developers by addressing their unique needs and challenges with specialized attention and resources. Our team operates across four core pillars: Marketing, Developer Relations, Growth Programs, and Sales. These functions work in close collaboration to support customers throughout their journey, from raising awareness and inspiring new use cases to driving platform adoption, consumption, and scaling customer relationships. Each function amplifies the impact of the others through strategic partnerships and shared insights. What you'll do You'll own the GTM-facing software and data products our sales motion runs on, end to end. That includes the data foundation underneath it and the signals that flag which accounts a rep should act on and when. You'll also lead our hardest cross-functional projects, the ones that span many teams and systems. You'll drive them to delivery, keep partner teams on track, and do it with a lot of autonomy. Day to day you'll improve how we visualize pipeline, build sales tools that flag the right moment to reach out to a customer, and make the developer buying journey smoother. The work is a mix of data engineering, full-stack product, and applied AI, and you'll build it on Cloudflare's own developer platform. This role fits someone who works well in a fast-paced, ambiguous environment, likes turning messy business problems into working software, and can juggle several priorities at once. Responsibilities • Design and implement features in a Golang, Typescript and SQL. • Build and operate production services on Cloudflare Workers and Kubernetes. • Own the data foundation including Query Engine, Workflows, MCP/APIs and other internal facing products and services. • Own projects end to end; from design docs and schema changes through implementation, testing, deployment, and production monitoring. • Participate in on call rotations, drive incident resolution, and write postmortems that improve reliability. • Use AI tools extensively to accelerate development, debugging, and operational tasks. We expect engineers to leverage AI as a core part of their workflow. • Collaborate across teams to coordinate capacity planning, API contracts, and cross cutting initiatives. • Embed with Sales, Marketing, Developer Relations (DevRel), and Growth to turn fuzzy operational pain into shipped software. • Help set the standard for GTM engineering organization wide. Desirable Skills, Knowledge, and Experience: At Cloudflare, we know that great candidates come from diverse backgrounds with non-linear paths. You don’t need to tick every single box to be right for this role. If you are excited about building a better Internet and ready to make an impact, please apply. • 10+ years of software engineering experience with a demonstrated history of leading complex, organization-wide data initiatives. • Deep expertise in building distributed systems and production infrastructure at scale, with proficiency in Go and strong working knowledge of TypeScript. • Exceptional ability to navigate ambiguous problem spaces, identify the highest-impact technical work, and drive projects autonomously from conception through adoption—balancing pragmatic execution with long-term technical excellence. • Deep analytical SQL and data modeling experience. Proven ability to manage complexity even at thousands of tables. • Able to debug database and query performance issues using profiling tools and source code where applicable. • Please be prepared to discuss specific examples of organization-wide technical initiatives you've led, particularly distributed systems or data infrastructure and their measurable business impact. Nice to have: • Previous experience as a Principal Engineer, Staff+ engineer, or technical leader on platform, infrastructure, or task force teams that operate outside traditional product roadmaps with a focus on enabling GTM organizations. • Columnar/OLAP or lakehouse experience (ClickHouse, DuckDB, BigQuery, Snowflake, Iceberg, Starrocks).Familiarity with the Salesforce data model and CRM/API integrations. • Familiarity with deploying to bare metal and Kubernetes. • Experience o
