Software Engineer, Product Growth and Experimentation

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.

We realize people do not fit into neat boxes. We are looking for curious and empathetic individuals who are committed to developing themselves and learning new skills, and we are ready to help you do that. We cannot complete our mission without building a diverse and inclusive team.

The Growth Engineering team is responsible for building world-class experiences that help the millions of Cloudflare self-service customers get what they need faster, from acquisition and onboarding all the way through to adoption and scale up.

This team has a dual mandate, also focusing on evolving our current marketing attribution, customer event ingress and experimentation capabilities that process billions of events across those properties to drive data-driven decision making.

We are looking for experienced full-stack engineers to join the Experimentation and Data Capture team. The ideal candidate will have experience working with large-scale applications, familiarity with event-driven data capture, and strong understanding of system design.

The Experimentation and Data Capture Engineering Team will be responsible for the following:

• Technical delivery for Experimentation and Data Capture capabilities intended for all of our customer-facing UI properties, driving user acquisition, engagement, and retention through data-driven strategies and technical implementations
• Collaborate with product, design and stakeholders to establish outcome measurements, roadmaps and key deliverables
• Own and lead execution of engineering projects in the area of web data acquisition and experimentation
• Work across the entire product lifecycle from conceptualization through production
• Build features end-to-end: front-end, back-end, IaC, system design, debugging and testing, engaging with feature teams and data processing teams
• Inspire and mentor less experienced engineers
• Work closely with the trust and safety team to handle any compliance or data privacy-related matters

Examples of desirable skills, knowledge and experience:

• Comfort with building reusable SDKs and UI components with TypeScript/JavaScript required, comfort/familiarity with other languages (Go/Rust/Python) a plus.
• Experience building with high-scale serverless systems like Cloudflare Workers, AWS Lambda, Azure Functions, etc.
• Design and execute A/B tests and experiments to optimize for business KPIs, including user onboarding, feature adoption, and overall product experience.
• Experience with publishing-to and querying-from data lake/warehouse products like Clickhouse, Apache Iceberg, to evaluate experiments.
• Implement tracking and attribution systems to understand user behavior and measure the effectiveness of growth initiatives.
• Familiarity with event driven architectures, high-scale data processing, issues that can occur and how to protect against them.
