CoreWeave’s Inference team builds and operates the core cloud platform powering massive-scale GPU workloads for AI/ML, VFX, rendering, and real-time inference. Our stack is engineered for speed, scale, and cost efficiency—providing a powerful alternative to traditional hyperscalers. Infrastructure is our product, and we operate it at massive scale to power the most demanding workloads.
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.
Who You Are:- ~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.
- Experienced in owning system-wide SLIs/SLOs, capacity planning, autoscaling strategies, and mentoring senior and mid-level engineers.
- Bachelor’s degree in Computer Science, Engineering, or a related technical field.
Preferred:
- 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.
