Senior Distributed Systems Engineer - CacheNew$194K–$266K

The Cache team builds and operates the high-performance reverse proxy and caching data plane at Cloudflare's edge. Built on Pingora, Cloudflare's open-source Rust framework for fast, reliable network services, this software serves cached content, routes traffic across cache…

What you'll do

• Design, build, and operate the high-performance cache and proxy data plane: that serves content at Cloudflare's edge and connects to customer origins

• Contribute to Pingora and the production services built on it, improving: asynchronous I/O, connection handling, memory and disk efficiency, and tail latency

• Improve cache correctness and performance through object placement,: retention, admission and eviction policies, range-request handling, and resilience to corrupt or incomplete data

• Build globally distributed purge and Tiered Cache systems that invalidate: content quickly, select efficient cache paths, improve hit rates, and reduce origin load

• Deliver shared platform capabilities and customer-facing APIs and rules for: cache keys, TTLs, response handling, purge behavior, and programmatic access from Workers

• Own features end to end: write technical designs, implement services and libraries, add automated tests and observability, drive staged rollouts, and operate the resulting systems in production

What they're looking for

• Participate in the team's on-call rotation, lead incident response and: post-mortems, and continually improve reliability, capacity, and operational tooling
• Reason carefully about failure modes and blast radius, using traffic cohorts,: measurable guardrails, and rollback mechanisms to introduce high-impact changes safely
• Partner with product and engineering teams across Cloudflare that depend on: or extend the cache and proxy platform
• Raise the engineering bar through code review, mentorship, clear written: communication, and improvements to team standards and tooling
