About The Position

Overview We are seeking a Senior Algorithm Software Architect to lead design and delivery of GPU‑accelerated, high‑performance computing software. You will set architectural direction, coach engineers, and partner with product and domain experts to deliver scalable, reliable systems for large‑scale compute and data workflows.

Responsibilities Own the end‑to‑end software architecture for HPC/GPU platforms (services, libraries, data pipelines, deployment) Lead technical strategy, decision records, define candidate architectures, lead design reviews and drive decisions; drive clear trade‑offs for performance, reliability, and maintainability Design and implement GPU kernels and frameworks (e.g., CUDA, OpenCL, NCCL), optimizing for throughput, latency, and memory use Guide parallel and distributed computing patterns (MPI, multi‑GPU scaling, heterogeneous compute) Establish performance engineering practices: profiling, benchmarking, regression performance gates (Nsight Systems/Compute, nvprof) Collaborate across functions; convert requirements into clear technical plans, roadmaps, and measurable outcomes Uphold engineering excellence: coding standards, code reviews, test strategies, observability, security considerations Mentor engineers; provide technical leadership on design, delivery, and career growth. Communicate architecture, risks, and status to executives and stakeholders with clarity and candor.

Qualifications 10+ years in software engineering; 5+ years in software architecture for HPC or large‑scale systems Expert in C++ (17/20) and one scripting language (Python preferred) GPU programming expertise (CUDA, OpenCL); strong knowledge of GPU memory hierarchies, streams, occupancy Hands‑on with parallel/distributed stacks (MPI, NCCL, gRPC) and Linux performance tooling Experience with cluster orchestration (Slurm, Kubernetes), CI/CD, and containerization (Docker) Track record of technical leadership and exceptional communication with cross‑functional teams.

Preferred / Nice‑to‑Have Multi‑node, multi‑GPU scaling; mixed precision; numerical methods and algorithms. Experience with H200/H100/A100/L40S‑class accelerators and modern profiling workflows.
