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.
- 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 authorization, or eligible and likely to obtain required authorization.
