Senior Systems Engineer - Application Security

About The Team

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!

About You

You must have at least 5 years of professional experience working hands-on as a software developer. We require proficiency with at least one of Go or Rust, plus exposure to devops tooling like but not limited to Kubernetes, Salt, Kafka or Systemd. Strong Linux / Unix fundamentals will be very helpful. You must have experience working with distributed systems at scale. Experience with cyber security is preferred but not essential.

Cloudflare’s culture is busy and multifaceted, and people who succeed here are persistent, have a can-do attitude and a genuine willingness to assume good faith in others. This last quality in particular requires them to be empathetic and emotionally intelligent, so you’re someone willing to take responsibility for the culture and environment that you create around you.

What You’ll Do

• 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.

Benefits

Cloudflare offers a positive and stimulating place to work, where you can enjoy friendly relationships with your colleagues and the freedom to have real impact on our products and customers. While the work is demanding, the company is unusual in offering an unlimited leave policy. This is not a “race to the bottom” or proxy for reducing the amount of leave taken; leaders around the company model the behaviour of always taking the time off that they need.

In addition to a competitive base salary, Cloudflare offers an equity program with stock grants on joining and regular refreshers linked to performance. And in common with other big tech companies, we offer medical and dental insurance, mental health support, a tax efficient defined contributions pension plan and life insurance.
