Sr. Software Engineer, Inference

What Youll Do:

CoreWeaves 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 efficiencyproviding an industry-defining platform that enables teams to deploy models with confidence. We work cross-functionally across organizational boundaries to deliver high-performance low-latency infrastructure at scale.

About the role:

As a Senior Software Engineer 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. This role involves leading design reviews decomposing multi-service work into clear milestones and owning critical infrastructure areas such as request routing adaptive scheduling cost-per-token analytics and GPU resource isolation. You will implement advanced optimizationsincluding micro-batch schedulers speculative decoding and KV-cache reusewhile evolving capacity planning autoscaling policies and mentoring engineers across the team.

Who You Are:

• 3 years of professional industry experience building distributed systems or high-performance cloud services.
• Strong software development skills in Python or Go alongside a deep familiarity with networked systems and performance optimization.
• Hands-on experience with Kubernetes at production scale including automated CI/CD and modern observability stacks (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.
• Experienced in defining and owning SLIs/SLOs managing capacity planning autoscaling policies and driving post-incident remediation.
• Bachelors or Masters degree in Computer Science or a related technical field (or equivalent practical experience).

Preferred:

• 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 (such as 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.
