- Collaborate with storage infrastructure, metadata, networking, and platform teams on API contracts, capacity planning, and cross-functional initiatives.
Requirements
- Strong programming skills in Rust, TypeScript, Go, or similar languages.
- Experience building or operating large-scale distributed systems on the request path with demanding latency and reliability requirements.
- Familiarity with object storage, HTTP/API gateways, edge computing, or service-oriented architectures.
- Experience designing and operating high-throughput APIs, including authentication, routing, rate limiting, and backward-compatible API evolution.
- Understanding of monitoring, alerting, performance tuning, and incident response.
- Strong written and verbal communication skills, with the ability to explain technical decisions and coordinate across teams.
- Comfort using AI coding tools in daily development workflows.
