About the Role
As a Staff Software Engineer (IC5) on the Inference team, you will operate as a technical leader across multiple teams and services, driving architecture, performance, and reliability for CoreWeave’s Kubernetes-native inference platform. You will define and lead complex, cross-cutting design initiatives spanning request routing, adaptive scheduling, GPU resource management, and cost-per-token optimization under strict P99 SLAs. This high-impact role requires you to implement advanced inference optimizations—such as speculative decoding and KV-cache reuse—while establishing performance benchmarking frameworks, guiding cross-functional alignment across infrastructure boundaries, and raising the bar for engineering rigor and observability practices.
Responsibilities
- Define and lead complex, cross-cutting design initiatives spanning request routing, adaptive scheduling, GPU resource management, and cost-per-token optimization under strict P99 SLAs.
- Implement advanced inference optimizations—such as speculative decoding and KV-cache reuse.
- Establish performance benchmarking frameworks.
- Guide cross-functional alignment across infrastructure boundaries.
- Raise the bar for engineering rigor and observability practices.
- Own system-wide SLIs/SLOs, capacity planning, and autoscaling strategies.
- Mentor senior and mid-level engineers.
Requirements
- ~8–12+ years of experience building large-scale distributed systems or cloud platforms.
- Proven track record of leading cross-team or organization-level technical initiatives at scale.
- Strong coding skills in Go, Python, or C++.
- Deep expertise in Kubernetes at production scale, including orchestration, scheduling, and service design.
- Strong understanding of networked systems, performance optimization, and distributed system design.
- Hands-on engineering experience with inference systems, including batching/micro-batching strategies, caching, memory optimization, mixed precision (BF16/FP8), and streaming token delivery.
- Demonstrated ability to systematically improve tail latency (P95/P99) and platform reliability through metrics-driven engineering.
- Bachelor’s degree in Computer Science, Engineering, or a related technical field.
- Direct open-source or production contributions to modern inference frameworks such as vLLM, Triton, TensorRT-LLM, Ray Serve, or TorchServe.
- Deep experience with GPU systems engineering and hardware performance optimization (CUDA, NCCL, RDMA, NUMA, or GPU interconnects).
- Direct exposure to large-scale AI/ML infrastructure or hyperscale cloud environments.
- Ability to scale highly complex distributed architectures and mentor engineering cohorts to elevate technical standards across an organization.
- Curiosity about pioneering low-latency inference optimizations and finding innovative shortcuts to optimize cost-per-token performance.
- Expertise in metrics-driven engineering, troubleshooting micro-bottlenecks, and delivering stable cloud platforms under strict multi-tenant constraints.
- Must be a U.S. person (U.S. citizen or national, U.S. lawful permanent resident, refugee, or asylee) or eligible to access export controlled information without required authorization, or eligible and likely to obtain required export authorization.
