About The Role
RadixArk's Compute & Business Operations team ensures we have the GPU and TPU capacity, vendor coordination, and operational discipline needed to power SGLang, Miles, and our production infrastructure. We work across Engineering, Finance, Product, and Research to keep compute predictable, cost-efficient, and aligned to company priorities. We're looking for a highly organized BizOps generalist who can thrive in a fast-moving, technical environment—someone who can track hardware inventory and contracts, coordinate procurement across cloud providers, manage cross-functional workflows, and surface risks early to keep our infrastructure running smoothly.
Requirements
Bachelor's degree in business, engineering, economics, computer science, or a related analytical field
3–6 years of experience in BizOps, technical program management, strategic operations, or similar roles involving complex, multi-stakeholder coordination
Strong analytical and quantitative skills; comfortable working with spreadsheets, metrics, and operational data
Excellent communication and documentation skills; able to create clarity, structure, and next steps in ambiguous environments
Highly organized with strong attention to detail and follow-through; able to manage many parallel workflows in a fast-paced startup environment
Experience coordinating cross-functional projects with engineering, finance, operations, and vendor partners
Ability to quickly learn technical concepts related to GPUs, TPUs, cloud infrastructure, and cluster operations (no prior deep expertise required)
Responsibilities
Track GPU and TPU inventory, allocations, availability, and incoming supply; coordinate forecasting with Product, Research, Engineering, and Finance teams
Maintain a consolidated view of compute contracts across providers (NVIDIA, Google, AWS, CoreWeave), including delivery schedules, renewals, acceptance criteria, SLAs, penalties, and cost exposure
Monitor provider performance, including outages, chronic issues, SLA adherence, delivery reliability, and surface risks early with clear, structured documentation
Build and maintain dashboards for utilization, inventory, uptime, and cost metrics; ensure data accuracy and drive actionable insights across teams
Coordinate cluster rollouts, expansions, and migrations by keeping timelines, dependencies, decisions, and documentation tightly aligned across Engineering and Infra teams
Support procurement workflows by coordinating internal requirements, preparing vendor documentation, managing approvals, and tracking POs, invoices, credits, and budget with Finance
Partner with Engineering to understand infrastructure needs for SGLang and Miles workloads and translate them into compute requirements
Create operational playbooks and processes for capacity planning, vendor management, and incident response
