About the role
TL;DR
Own and architect the CI infrastructure for an open-source LLM inference engine.
- •RadixArk is hiring a Member of Technical Staff
- •CI / Infrastructure to own the infrastructure that keeps SGLang moving.
- •Our CI system runs 300+ GPU tests across NVIDIA, AMD, Intel, and Ascend hardware pools, gating every commit to one of the fastest-growing open-source LLM inference engines.
- •When CI is green and fast, 100+ contributors ship with confidence.
- •When it isn't, the entire project stalls.
- •That bottleneck is your problem to solve.
- •You won't just maintain pipelines
- •you'll architect them.
- •You'll replace brittle static thresholds with regression-based detection, harden runners against supply-chain attacks from fork PRs, and cut cycle times so contributors get feedback in minutes, not hours.
- •You'll work directly with core maintainers, hardware partners, and the open-source community to keep the system that gates every merge request trustworthy, fast, and secure.
- •This is not a role for someone who wants to write CI YAML and walk away.
- •It's for an engineer who treats CI infrastructure the way we treat serving infrastructure
- •as a system worth designing well.
