Senior Systems Engineer, Cloud App Control

Available Location: Sydney, Australia
About the Department
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 One 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.
What you'll do
In this role you'll help us build features within Gateway, an ambitious product that aims to be the most secure and performant method for an organization's devices to connect to the Internet. As an engineer on the Cloud App Control team, you will focus on our high-performance global edge network data plane services and will also contribute to the control plane API's 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 deployable forward-proxy that runs inside customer networks responsible for inspecting and filtering cloud API traffic to preventatively secure IaaC workloads.
• 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 200+ data centers
• Our deployable proxy is written in Go providing a single binary that is easy for customers to integrate within their overall architecture.
• 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.
