Member of Technical Staff (Infrastructure): World Models

What You'll Do Collaborate with researchers and engineers to understand workload requirements and translate them into infrastructure decisions — not just run what you're given. Design and improve scheduling and resource allocation for inference and training coexistence on shared GPU clusters. Build, operate, and scale GPU infrastructure across clusters of thousands of GPUs. Own GPU utilization and cost as first-class metrics. Build automated tooling and observability that reduces friction for the AI team. Participate in on-call rotation and drive reliability improvements. Serve as the primary point of contact for GPU providers, managing relationships and coordinating infrastructure needs. Over time , you'll take on broader ownership: setting scheduling policy, driving architecture decisions for compute and storage systems, and identifying when infrastructure no longer fits evolving workloads. What We're Looking For Deep Systems Foundation: Linux-native. Understands how machines work, can debug at the kernel level. Deep understanding of networking and storage stacks. Cluster Engineering: Experience operating and scaling GPU infrastructure (hundreds to thousands of GPUs), Kubernetes, Slurm, and distributed storage systems. Distributed Systems Fundamentals: Experience designing, building, and operating distributed systems at scale. Production Discipline: Track record of running critical infrastructure reliably — monitoring, incident response, and automation that reduces toil. ML Familiarity: Enough understanding of training and inference workloads to collaborate with researchers and make sound infrastructure decisions. Bonus: Resource-Constrained Thinking. Experience in environments where allocation, scheduling, and prioritization of scarce resources was the core problem (e.g. HPC, trading, large-scale ML platforms). Challenges You'll Tackle Balancing latency-sensitive inference against long-running training workloads Operating under tight GPU constraints with constantly shifting demand Adapting infrastructure to rapidly evolving model architectures and scale Making tradeoffs between cost, utilization, and reliability at scale Traits of the Ideal Candidate High ownership: Owns problems end-to-end, sets priorities, and escalates early. Challenges systems: Questions what exists and drives improvements when it no longer fits. Learns fast: Quickly builds context to make sound infrastructure decisions. Thinks in systems: Understands dependencies, validates assumptions, and catches issues early. Raises the bar: Shares context, surfaces risks, and helps the team move faster. What we offer (compensation & benefits) Competitive salary and equity Private health coverage Pension contribution (UK, Canada, US) Unlimited paid vacation Fully-distributed, async-first culture Hardware setup of your choice Stipends for phone, internet, and meals In our team, we approach our work with the dedication similar to Olympic athletes. Anticipate occasional late nights and weekends dedicated to our mission. We understand this level of commitment may not suit everyone, and we openly communicate this expectation. If you're motivated by deeply technical problems, a seemingly never-ending uphill battle and the opportunity to build (and own) a generational technology company, we can give you what you're looking for. All business roles at Moonvalley are hybrid positions by default, with some fully remote depending on the job scope. We meet a few times every year, usually in London, UK or North America (LA, Toronto) as a company. If you're excited about the opportunity to work on cutting-edge AI technology and help shape the future of media and entertainment, we encourage you to apply. We look forward to hearing from you!
