Software Engineer - GenAI inference

Databricks

P-1284 About This Role As a software engineer for GenAI inference, you will help design, develop, and optimize the inference engine that powers Databricks’ Foundation Model API. You’ll work at the intersection of research and production, ensuring our large language model (LLM) serving systems are fast, scalable, and efficient. Your work will touch the full GenAI inference stack — from kernels and runtimes to orchestration and memory management. What You Will Do - Contribute to the design and implementation of the inference engine, and collaborate on model-serving stack optimized for large-scale LLMs inference - Collaborate with researchers to bring new model architectures or features (sparsity, activation compression, mixture-of-experts) into the engine - Optimize for latency, throughput, memory efficiency, and hardware utilization across GPUs, and accelerators - Build and maintain instrumentation, profiling, and tracing tooling to uncover bottlenecks and guide optimizations - Develop and enhance scalable routing, batching, scheduling, memory management, and dynamic loading mechanisms for inference workloads - Support reliability, reproducibility, and fault tolerance in the inference pipelines, including A/B launches, rollback, and model versioning - Integrate with federated, distributed inference infrastructure – orchestrate across nodes, balance load, handle communication overhead - Collaborate cross-functionally: with platform engineers, cloud infrastructure, and security/compliance teams - Document and share learnings, contributing to internal best practices and open-source efforts when possible What We Look For - BS/MS/PhD in Computer Science, or a related field - Strong software engineering background (3+ years or equivalent) in performance-critical systems - Solid understanding of ML inference internals: attention, MLPs, recurrent modules, quantization, sparse operations, etc. - Hands-on experience with CUDA, GPU programming, and key libraries (cuBLAS, cuDNN, NCCL, etc.) - Comfortable designing and operating distributed systems, including RPC frameworks, queuing, RPC batching, sharding, memory partitioning - Demonstrated ability to uncover and solve performance bottlenecks across layers (kernel, memory, networking, scheduler) - Experience building instrumentation, tracing, and profiling tools for ML models - Ability to work closely with ML researchers, translate novel model ideas into production systems - Ownership mindset and eagerness to dive deep into complex system challenges - Bonus: published research or open-source contributions in ML systems, inference optimization, or model serving Pay Range Transparency Databricks is committed to fair and equitable compensation practices.
