About the Role
Cloudflare’s Engineering Team builds and runs the software that handles trillions of requests per month. Product development covers both new features and functionality and scaling our existing software to meet the challenges of a massively growing customer base.

The Cloudflare Zero Trust group within the Engineering organization is taking on the mission of ensuring the people and teams within an organization can access the tools they need to do their job safe from malware and other online threats with the speed and reliability that Cloudflare is known for.

Key Responsibilities
In this role you’ll help us build Gateway and DNS Filtering products, ambitious products that aim to be the most secure and performant method for an organization’s devices to connect to the Internet. As an engineer on the Gateway teams, you will focus on our high-performance global edge network data plane services and will also contribute to the control plane APIs that configure the edge services. You will be joining a global team of bright, hard-working, and supportive engineers who really care about their craft.

Example of systems that the team currently is building:

• A forward-proxy service running on every machine of Cloudflare’s extensive edge network, responsible for inspecting, filtering, and blocking device requests based on an organization’s configured policy;
• A DNS resolver running on our edge that leverages a Wirefilter based filtering rules engine;
• Microservices that allow organizations to configure, manage, and observe their organization's devices and their respective traffic.

Technologies we use:

• Gateway’s core edge services are written in Rust and deployed globally to 310+ data centers;
• Our REST API is written in Go, runs on Kubernetes, and uses Postgres as a data store;
• Our frontend is written in Typescript and React;
• For service monitoring we use Prometheus and Grafana;
• For service logging we use Elasticsearch and Kibana;
• For product analytics we use Clickhouse and BigQuery.

Because you’ll be solving problems of massive scale and significance, and shaping the future of the Internet, you are a growth-oriented individual who enjoys being outside of your comfort zone in a fast-paced environment.

Examples of desirable skills, knowledge and experience
As an ideal candidate for this position, you are curious, hard-working, and passionate.

A rough list of the skills we would love to see you bring:

• Programming experience in Rust, C++, or similar low level languages
• Programming experience in Go and/or Typescript is a plus, but not required
• A strong grasp of networking protocols in Layers 3-7 of the OSI Model
• Solid understanding of HTTP protocols - including experience with HTTP/2 and bonus for HTTP/3 experience
• Basic understanding of software security and encryption
• Experience in designing and implementing secure and highly-available distributed systems
• Willingness, curiosity, and enthusiasm to learn new programming languages, technologies, and systems
• Strong interpersonal and communication skills. Caring and empathy are coveted traits here
