Role
Who you are
- You thrive in a fast-paced iterative engineering environment
- At least 2 years of recent professional experience with C++ or Rust
- Solid understanding of computer science fundamentals including data structures, algorithms, and object-oriented or functional design
- An operational mindset - we don't just write code, we also own it in production
- Deep understanding of the web and technologies such as web browsers, HTTP, JavaScript and WebAssembly
- Experience working in low-latency real time environments such as game streaming, game engine architecture, high frequency trading, payment systems
- Experience debugging, optimizing and identifying failure modes in a large-scale Linux-based distributed system
Desirable
- Experience building high performance distributed systems in Rust
- Experience working with cloud platforms, especially server-less platforms
- Experience with the internals of JS engines such as V8, SpiderMonkey, or JavaScriptCore
- Experience with standalone WebAssembly runtimes such as Wasmtime, Wasmer, Lucet, etc
- Deep Linux/UNIX systems, kernel, or networking knowledge
- Contributions to large open source projects
What the job involves
- The Workers Runtime team delivers features and improvements to our Runtime which actually executes customer code at the edge
- We care deeply about increasing performance, improving JS API surface area and compiled language support through WebAssembly, and optimizing to meet the next 10x increase in scale
- The Runtime is a hostile environment - System resources such as memory, cpu, I/O, etc need to be managed extremely carefully and security must be foundational in everything we do
- We are looking for a Systems Engineer to join our team
- You will work with a team of passionate, talented engineers that are building innovative products that bring security and speed to millions of internet users each day
- You will play an active part in shaping product features based on what’s technically possible
- You will make sure our company hits our ambitious goals from an engineering standpoint
- You bring a passion for meeting business needs while building technically innovative solutions, and excel at shifting between the two—understanding how big-picture goals inform technical details, and vice-versa
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.
