Role
Who you are

- Serverless Architecture: Experience building with high-scale serverless systems (e.g., Cloudflare Workers, AWS Lambda, Azure Functions)
- Growth & Analytics: Experience designing interfaces for business KPIs (onboarding, adoption), running A/B experiments, using feature flags/gating, and leveraging telemetry
- System Design & APIs: Strong foundation in system design—balancing engineering excellence with visual aesthetics—and experience working with or designing RESTful APIs

What the job involves

- Experimentation & Growth: Deliver customer-facing UI experiences and A/B experiments aimed at accelerating user acquisition, engagement, and retention through data-informed hypotheses
- Full-Stack Execution: Architect scalable front-end solutions and build features end-to-end across the product lifecycle (front-end, back-end, IaC, system design, debugging, and testing)
- Cross-Functional Collaboration: Partner with product, design, and data/analytics teams to define outcome measurements, establish experimental frameworks, track behavior attribution, and shape product roadmaps
- Performance & Productivity: Enhance application performance, code quality, security, and developer productivity across core properties
- Trust & Safety Compliance: Work with cross-functional teams to ensure all product experiences comply with trust and safety principles
Our take
Cloudflare is a multi-service global network that provides web security and infrastructure, DDoS mitigation services, and a content delivery network. Founded in 2009, Cloudflare has risen to become an industry giant, with over 25 million global internet properties on its network.
Cloudflare has been responsible for a number of admirable initiatives, offering free web protection to human rights groups, journalists, artists, and US election websites. This goes some way to counteracting the flak Cloudflare has received in some circles for the controversial groups and users who use its services. This chequered history, however, has not affected its over 80% market share in the content delivery network field.
This is perhaps in part because it has proven sharp at staying abreast of the rapidly morphing tech and digital space and customer demands. For example, Cloudflare is shifting to 100% renewable energy usage to create a zero-emissions internet, and in 2020 released a feature that would help users navigate data privacy regulations by selecting where their data is stored.
And impressive third-quarter 2025 results show strong momentum, with revenue rising to $562 million from $430 million a year earlier. The company also raised its full-year guidance, underscoring confidence in continued growth. As demand for secure, cloud-based infrastructure keeps growing, Cloudflare's expanding platform and improving efficiency leave it well positioned to capture further gains in a rapidly growing market.
