About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role We run one of the industry's largest AI compute fleets, spanning multiple cloud providers and datacenters, to train, research, and serve frontier AI models. Those fleets run on Kubernetes, and the Kubernetes Platform team owns the control plane that makes them work. We are operating at a scale where the defaults stop working. We own the scheduler and extend it to place topology-sensitive ML workloads across thousands of accelerators at once. We scale the control plane itself — apiserver, etcd, controllers — so it stays responsive as object counts and node counts grow by orders of magnitude. And we build the core cluster services every workload depends on, like service discovery, so they hold up under the same pressure. We make sure the control plane is fast, correct, and always available. Your work will directly determine whether Anthropic can keep reliably and safely training frontier models as our compute footprint continues to grow. Key responsibilities Own, operate, and extend the Kubernetes scheduler for Anthropic's accelerator fleets, including custom scheduling plugins and policies for gang scheduling, topology awareness, and preemption Scale the Kubernetes control plane (apiserver, etcd, controller-manager) to support clusters far beyond typical limits, and find the next bottleneck before it finds us Design, build, and operate core cluster services such as service discovery that every workload in the fleet depends on Build and maintain custom controllers, operators, and CRDs Partner with research, training, and inference to understand workload shapes and turn their requirements into platform capabilities Collabo

As a SoC Physical Design Engineer in the Heterogeneous Integration Group (HIG), you will drive the implementation of advanced HBM SoC logic/base die designs from netlist to GDSII. You will work closely with RTL design, verification, DFT, IP providers, packaging/assembly, and manufacturing teams to deliver best‑in‑class PPA (performance, power, area) and robust signoff collateral for tape-out. This is a hands‑on role with opportunities to own blocks or top‑level integration across multiple product generations. Key Responsibilities Own physical implementation for SoC blocks and/or top-level, including floor-planning, placement, CTS, routing, and physical optimization to meet PPA targets. Drive timing closure (setup/hold) across multi-mode/multi-corner (MMMC) scenarios; partner with RTL, architecture, and STA/signoff to converge designs. Integrate and implement complex IP (e.g., controllers, microcontrollers, NOC, interfaces, MBIST/DFT logic, buffers, PHY‑adjacent logic) with focus on robust physical integration and timing/power integrity. Perform and/or coordinate physical signoff, including DRC/LVS, IR drop/EM, and timing signoff, addressing violations efficiently. Partner with DFT teams to ensure scan/MBIST requirements are physically realizable and do not compromise PPA or schedule. Work with packaging, assembly, test, probe, and manufacturing collaborators to ensure builds meet manufacturability and quality requirements.
