Role Summary

Workers Observability (WOBS) Team provides a growing suite of tools to monitor, troubleshoot and optimize applications on the Cloudflare Developer platform. These tools increasingly work across Cloudflare products to provide complete visibility into user applications. We aim to make these tools not only best-in-class but also frictionless and intuitive to use. All this within the context of Cloudflare's scale and globally distributed infrastructure.

Team members help design and ship core software features across the observability stack - including the frontend customer experience, integrations with other Cloudflare primitives, and our internal data stores and ingestion pipelines. You will own code across the development lifecycle from design to release including QA, incident management, and performance optimization.

The Systems Engineer role is a full-stack position which requires extensive cross-functional collaboration. On a given day you might incorporate frontend feedback from a customer, run a Clickhouse query to diagnose a data ingestion bug, and propose a better tracing integration with another product on the Workers platform.

Role Responsibilities

Customer Focus: Be responsive to customer escalations, bug reports, and product feedback, and participate in pager duty for our production systems.
Software Development: Efficiently and reliably deliver high-quality software that meets the performance requirements of Cloudflare’s systems.
Troubleshooting: Address complex and subtle issues on our platform, which may require debugging across multiple systems, languages, and datastores.
Communication: Maintain clear written communication across a range of platforms as part of a globally distributed team (from US West Coast to UK) and across a range of different engineering and support teams.

Expertise: Success in this role will depend on becoming an expert not just on the observability platform, but on the Cloudflare Developer Platform as a whole.

Role Requirements (Must-Have Skills)

Must-Have Skills

Strong proficiency in at least one programming language, preferably a typed language (e.g. Go, TypeScript, Rust) as well as SQL

Experience troubleshooting distributed data systems including working with logs and data stores.

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
