What You'll Do / Responsibilities Quicksilver is Cloudflare’s globally distributed key‑value store. It replicates our data all around the world, over tens of thousands of servers and over 500 data centers. It handles all kinds of network conditions and serves billions of keys per second. In this role, you will own and support the whole stack: the code base, the unit and integration tests, deployment and rollback plans, operations, monitoring, alerting, debugging and on‑call. Quicksilver is written in Go and C. If working at this scale excites you and you are intrigued by very tricky bugs, rather than being scared by them, you might be a match for this role.
Work on our distributed large‑scale key‑value store, write new features in Go and review pull requests
Improve performance, CPU, memory usage, etc.
Improve monitoring and tooling, all written in Go
Help debug and investigate hard‑to‑reproduce problems
Requirements
Previous experience writing robust systems with an emphasis on code quality, performance and technical debt
Proven experience with storage systems, peer‑to‑peer systems, large‑scale distributed systems or system programming
Ability to chase problems through multiple layers of the software stack, with curiosity and flexibility
Strong autonomy and independent problem‑solving, with a track record of designing simple yet powerful solutions
Comfort with both low‑level and high‑level programming and a taste for programming languages
Active contribution to a team that challenges designs, giving and receiving constructive criticism to produce the best solutions
Comfortable engaging in outages, possibly during anti‑social hours
What Makes Cloudflare Special? We’re not just a highly ambitious, large‑scale technology company. We’re a company that cares deeply about 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.
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. To date, 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 build a faster, more secure, and privacy‑centric public DNS resolver. It is available publicly for everyone to use – we never store client IP addresses and keep a strict privacy commitment.
