Senior Systems Software Engineer, Performance Architecture - Analytics and Data Intelligence

Overview Job Requisition ID: JR2019714 Job Category: Engineering Time Type: Full time NVIDIA’s Analytics and Data Intelligence (ADI) organization is building the next generation of GPU-accelerated data analytics, data science, and vector search systems. This role focuses on performance architecture for GPU-accelerated structured data processing and involves developing coordinated SQL and user-friendly interfaces across diverse CPU and GPU query engines, improving performance, reliability, and workload optimization. What You’ll Be Doing Extend JIT and compiler-based execution support in cuDF and related GPU-accelerated structured data processing systems. Design approaches for lowering expressions, ASTs, or query fragments into optimized GPU execution paths. Investigate kernel fusion strategies across cuDF operations to reduce materialization, memory traffic, launch overhead, and end-to-end query latency. Analyze structured analytics workloads to identify performance bottlenecks in expression evaluation, joins, aggregations, scans, data movement, and memory management. Build benchmarks and regression tests that capture real dataframe and SQL-like workloads, from micro-benchmarks to end-to-end pipelines. Collaborate with cuDF, CUDA, compiler/runtime, and query engine teams to translate workload analysis into implementation plans and architecture decisions. Prototype and evaluate execution strategies inspired by high-performance database engines, including fused operators, code generation, vectorized execution, and adaptive planning. What We Need To See Bachelor's or Master's degree in Computer Science, Computer Engineering, or a related field, or equivalent hands-on experience. 12+ years of validated experience in systems performance engineering or performance-focused architecture. Proven skills in profiling, instrumentation, and optimization for CPU and GPU systems, applying tools like tracing, counters, flame graphs, and kernel-level profiling. Experience with compiler, JIT, code generation, query execution, or runtime optimization techniques. Experience optimizing analytic database engines and/or query runtimes, including vectorized execution, join strategies, and columnar formats like Arrow and Parquet. Proficient in C++ and/or Python, with a strong ability to analyze performance-critical code and implement effective solutions. Experience with cuDF, RAPIDS, CUDA, Numba, LLVM, MLIR, NVRTC, or other JIT/codegen systems. Experience with benchmarking frameworks, performance dashboards, and CI/CD regression gating, along with a proven grasp of modern analytics and machine learning workflows. Ways To Stand Out From The Crowd Deep familiarity with NVIDIA GPUs and GPU programming (CUDA), including memory hierarchy, concurrency, and profiling toolchains such as Nsight Systems. Experience with TPC-style benchmarking (TPC-H, TPC-DS, or analogous), Click-Bench-like workloads, and building credible, repeatable performance narratives. Prior work on database execution engines, especially operator fusion, query compilation, vectorized execution, or adaptive execution. Demonstrated open-source contributions to performance-critical systems, including libraries, runtimes, databases, and ML or data tooling. With a competitive salary package and benefits, NVIDIA is widely considered to be one of the technology world’s most desirable employers. We have some of the most forward-thinking and hardworking people in the world working for us. Are you a creative and autonomous Systems Software Engineer, who loves challenges?
