Must have
Bachelor’s or Master’s degree in Computer Science or a related technical field (or equivalent practical experience).
3+ years of professional industry experience building distributed systems or high-performance cloud services.
Strong software development skills in Python or Go, alongside deep familiarity with networked systems and performance optimisation.
Hands-on experience with Kubernetes at production scale, including automated CI/CD and modern observability stacks (e.g., Prometheus, Grafana, OpenTelemetry).
Practical, working knowledge of inference internals: batching strategies, caching, mixed precision (BF16/FP8), and streaming token delivery.
Proven track record of improving tail latency (P95/P99) and service reliability through metrics-driven engineering work.
Experience defining and owning SLIs/SLOs, managing capacity planning, autoscaling policies, and driving post-incident remediation.
Nice to have
Experience with low-level systems and high-performance computing components (e.g., C++ development, CUDA kernels, NCCL/SHARP, RDMA/NUMA, or GPU interconnect topologies).
Active open-source or production contributions to modern inference frameworks (e.g., vLLM, Triton, TensorRT-LLM, Ray Serve, or TorchServe).
Experience leading multi-team technical initiatives or partnering directly with enterprise customers on mission-critical platform launches.

We're proud to be a Living Wage accredited Employer.
What You'll Do:
CoreWeave’s Inference team builds and operates the core cloud platform powering massive-scale GPU workloads for generative AI and real-time inference applications. Our stack is engineered natively on Kubernetes for maximum speed, scale, and cost efficiency—providing an industry-defining platform that enables teams to deploy models with confidence across organizational boundaries.
About the role:
As a Senior Software Engineer, Inference, you will serve as an area owner responsible for leading technical designs, raising engineering standards, and delivering measurable improvements across multiple services. You will partner with product, orchestration, and hardware teams to evolve our Kubernetes-native inference platform while meeting strict P99 SLAs at scale. In this role, you will lead design reviews, decompose multi-service work into clear milestones, and own critical infrastructure areas such as request routing, adaptive scheduling, cost-per-token analytics, and GPU resource isolation. Additionally, you will implement advanced optimizations—including micro-batch schedulers, speculative decoding, and KV-cache reuse—while refining capacity planning, autoscaling policies, and mentoring engineers across the team.
