## Description

At Cloudflare, we're not looking for people who wait for a polished roadmap; we're looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you're the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you'll fit right in.

What you'll do

In this role, you'll help build and maintain Data Security products as a Software Engineer. These products empower customers to gain deep visibility into Cloud/SaaS security opportunities and into trends in their network traffic and product use. As an engineer on the team, you will focus on building new functionality into our APIs and distributed code while ensuring the performance and reliability of our services which ingest millions of data points each day. You'll be joining a team of bright, knowledge-seeking engineers who are truly missionaries in solving the security and network visibility challenges for our customers.

Technologies we use:

 * Products are written in Go, Python, and Typescript.
 * Code runs on Kubernetes, Cloudflare Workers, AWS, GCP, Azure.
 * We utilize Postgres as our data store, Redis as our cache, and Kafka as our message broker.
 * 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.
