Senior Systems Engineer (Application Security)

• Application Security is responsible for Cloudflare’s fast-growing security product portfolio including WAF, Page Shield, Web Asset Management and API Shield
• Being part of Cloudflare means working at internet scale and we are uniquely positioned to tackle challenging problems related to being connected to more networks, websites and customers than any other provider worldwide
• Working at great scale by default (to an extent not offered by most other employers in big tech) means pushing boundaries well beyond what commodity solutions like Nginx and Kafka provide out of the box
• You’ll be working with custom components that have been created in an engineering-driven and pragmatic way - our code is well-tested and documented and uses modern ecosystems like Go and Rust
• This gives you confidence that you will spend your time having an impact and not firefighting!
• You’d be joining a high-profile part of the business that can really accelerate and support your career. Cloudflare has a strong track record of growing in a thoughtful way and hires carefully so we’re confident that you will enjoy working with your colleagues here!
• Design systems and write code following bleeding edge industry best practices and help others on the team do the same. Review RFCs, technical specifications and code
• Deploy and maintain live software-based services at scale (up to 100m requests / second, 1m customers). Take regular shifts as part of the team’s On Call rota
• Support and grow other Engineers through knowledge sharing
• Keep up to date with trends in detecting current and emerging security risks to web applications and provide input on how these impact Cloudflare’s products
• Work with Engineers and Product Managers outside your immediate team in communicating our roadmap and getting things done
