  • Someone who enjoys security work focused on email detections that identify and protect our users
  • Distributed systems experience in a Unix environment

What the job involves

  • Cloudflare’s Cloud Email Security (CES) service builds advanced technology focused on the source of 95% of data breaches on the internet: phishing
  • Hunting for bad actors on the internet is an intellectual and technical challenge. We hunt at scale with web crawling, machine learning, computer vision, petabytes of data, and a global network of sensors
  • All of this technology delivers a comprehensive email, network and web protection layer around each of our customers. Customers know that with Cloudflare CES solution deployed their users won’t enable a hacker to gain a foothold that results in a breach of their systems
  • Come and join an engineering team that builds extensible, reliable, scalable web-based, and data processing applications that our customers count on every second of the day
  • Create the product’s subsystems and key components by applying up-to-date expertise in Software Engineering to define, design and create world-class implementations
  • Collaborate with other senior engineers to improve the overall system at the architectural, design, and implementation levels
  • Design and implement new features for our cloud-based email gateway solution that empowers Fortune 1000 customers
  • Design and implement forward-looking portions of the system to execute a long-term product vision
  • Work with large scale data systems in both online/streaming and offline/batch fashions
  • Design and implement revisions to areas of the system to enhance key features such as performance, reliability, scalability, or add new functionality

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 around 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.

The cloud infrastructure market reached $53 billion in 2022. While the Big 3 (Amazon, Microsoft, and Google) own 65% of the market, that still leaves billions of dollars left for companies such as Cloudflare. Its ambitious and successful work is likely to continue being a crucial feature of the web, but in 2023, placed it in the crosshairs of hackers looking to exploit its infrastructure. The beginning of 2024 saw Cloudflare vow to bolster its security and patch vulnerabilities.
