Senior Software Engineer, R2 Metadata

Hybrid

Responsibilities

Design and implement features in a metadata system, backed by a distributed SQL DB, that serves every R2 API operation, ensuring correctness, performance, and compatibility with the S3 API surface.
Build and operate production services on Cloudflare Workers and Kubernetes that handle high throughput metadata operations with strong consistency and durability guarantees.
Own the schema, data model, and query patterns for a metadata layer managing billions of objects across multiple distributed database clusters.
Own projects end to end; from design docs and schema changes through implementation, testing, deployment, and production monitoring.
Collaborate across teams (storage infrastructure, networking, other platform teams) to coordinate capacity planning, API contracts, and cross cutting initiatives.

As a result, they see significant improvement in performance and a decrease in spam and other attacks.
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.
Use AI tools extensively to accelerate development, debugging, and operational tasks. We expect engineers to leverage AI as a core part of their workflow.
Strong programming skills in TypeScript, Go, or similar languages. •
Experience with distributed databases; schema design, query optimization, indexing strategies, and understanding consistency/performance tradeoffs at scale. •
Familiarity with cloud infrastructure concepts such as object storage, edge computing, or service oriented architectures.
Understanding of reliability and observability practices: monitoring, alerting, performance tuning, and incident response.
Strong written and verbal communication skills; ability to explain technical decisions clearly and coordinate across teams.
