Excellent programming skills, with experience writing very high-quality and low-complexity code with thorough documentation

What the job involves

We’re looking for a Senior Windows Software Engineer to join our Zero Trust team. You will be working on the Zero Trust desktop client, which protects corporate devices by securely and privately sending traffic from those devices to Cloudflare’s global network, which can apply advanced web filtering and advanced Zero Trust policies
In your role, you will predominantly be using Rust along platform-native languages & APIs to implement high-performance networking code that runs on multiple desktop platforms
You’ll be expected to improve the code quality and to build solid, testable, and well-documented foundations
You will be most successful in this role if you have a good understanding of Windows internals (virtual memory, multi-threading, process lifecycle, kernel programing, system APIs, etc.) and networking protocols (TCP/IP, UDP, DNS, QUIC, H/3, proxying, etc.)
You will also have to interact with other languages, such as Swift, C#, C, and python
As a Senior Software Engineer, you will be expected to make significant contributions to the design and implementation of major development projects, working closely with our product managers and other teams to implement customer-impacting features
You will work on stimulating problems born out of the scale of our deployment, and the stringent quality, performance, and security requirements of our product

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.
