Staff Software Engineer, Inference--------------------------------------

Location: London, England

What You'll Do:

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 where infrastructure is our core product operated at massive scale.

About the role:

As a Staff Software Engineer 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 optimisation under strict P99 SLAs. In this high-impact role, you will implement advanced inference optimisations—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 rigour and observability practices across the organisation.

Who You Are:

• Bachelor's degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience).
• 8+ years of experience building large-scale distributed systems or cloud platforms, with a proven track record of leading cross-team or organisation-level technical initiatives at scale.
• Strong coding proficiency in Go, Python, or C++.
• Deep expertise in Kubernetes at production scale, including orchestration, scheduling, and service design.
• Strong understanding of networked systems, performance optimisation, and distributed system design.
• Hands-on engineering experience with inference systems, including batching/micro-batching strategies, caching, memory optimisation, mixed precision (BF16/FP8), and streaming token delivery.
• Demonstrated ability to systematically improve tail latency (P95/P99) and platform reliability through metrics-driven engineering.
• Proven experience owning system-wide SLIs/SLOs, capacity planning, autoscaling strategies, and mentoring senior and mid-level engineers.

Preferred:

• Direct open-source or production contributions to modern inference frameworks (e.g., vLLM, Triton, TensorRT-LLM, Ray Serve, or TorchServe).
• Deep experience with GPU systems engineering and hardware performance optimisation (e.g., CUDA, NCCL, RDMA, NUMA, or GPU interconnects).
• Direct exposure to large-scale AI/ML infrastructure or hyperscale cloud environments.

Wondering if you're a good fit?-----------------------------------

We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams—even if you aren't a 100% skill or experience match.

• You love to: Scale highly complex distributed architectures and mentor engineering cohorts to elevate technical standards across an organisation.
• You're curious about: Pioneering low-latency inference optimisations and finding innovative shortcuts to optimise cost-per-token performance.
• You're an expert in: Metrics-driven engineering, troubleshooting micro-bottlenecks, and delivering stable cloud platforms under strict multi-tenant constraints.
