RadixArk is building the infrastructure layer for frontier AI systems — unified inference, training, and evaluation stacks powering next-generation LLM applications at scale.
RadixArk is the employer — EngRadar is a job radar, not a recruiter. We track this posting from their own careers page and send you straight there; we never handle applications or CVs.
We're looking for a Head of Business Development to build the BD function at RadixArk from the ground up. The BD team is the institutional memory of this company — maintaining active relationships across every customer we've touched, detecting signals early, and ensuring nothing falls through the cracks. You'll design the system, build the team, and run it.
The role is equal parts relationship and rigor. You'll hold the relationship thread across a broad customer surface while tracking coverage rates, handoff volume, signal trends, and engagement quality — and translating that into clear intelligence for the broader commercial organization.
We move fast, operate with a sense of urgency, and expect the same from everyone on the team.

RadixArk is an infrastructure-first company built by engineers who've shipped production AI systems, created SGLang (20K+ GitHub stars, the fastest open LLM serving engine), and developed Miles (our large-scale RL framework).

Our team has optimized kernels serving billions of tokens daily, designed distributed training systems coordinating 10,000+ GPUs, and contributed to infrastructure that powers leading AI companies and research labs.
We're backed by well-known infrastructure investors and partner with Nvidia, Google, AWS, and frontier AI labs. Join us in building infrastructure that gives real leverage back to the AI community.
