Requirements

  • A foundation in infrastructure, platform engineering, distributed systems, high-performance computing, or machine-learning technologies, with the ability to participate in module design, development, deployment, and troubleshooting.
  • A solid foundation in Linux, networking, storage, and operating systems, with the ability to analyze resource usage and diagnose performance and stability issues.
  • Proficiency in at least one programming language, such as Python, Go, C++, Rust, or Java, and good coding and engineering practices.
  • Knowledge of containers, task scheduling, and resource management, and familiarity with at least one of Kubernetes, Slurm, Ray, or a comparable system.
  • Understanding of basic machine-learning model training and inference workflows, with practical model-training or related project experience, and knowledge of data I/O, compute-resource, and runtime-environment requirements.
  • Knowledge of CI/CD, Infrastructure as Code, monitoring and alerting, and automated operations, with attention to observability, reproducibility, and fault recovery.
  • Ability to learn, communicate, collaborate, understand research needs, analyze technical trade-offs, and help implement solutions.

Responsibilities

  • Build and optimize GPU/CPU resource management and job-scheduling systems to improve compute-resource utilization and job efficiency.
  • Support multi-GPU and multi-node computing tasks, optimizing data loading, task parallelism, node communication, and fault recovery.
  • Optimize large-scale data reading, caching, and storage access, and identify and improve compute, network, and I/O bottlenecks.
  • Develop job-submission, experiment-management, development-environment, and dependency-management tools to improve research efficiency and reproducibility.
  • Support deployment and operation of model-training, batch-inference, and online-inference tasks, and improve version management, monitoring, and fault recovery.
  • Build automated operations, monitoring and alerting, access-control, and resource-quota capabilities to improve system reliability.
  • Collaborate with research and engineering teams to turn shared needs into usable, reusable platform capabilities.

Desired Qualifications

  • Experience in quantitative investment, hedge funds, machine-learning platforms, or large-scale research-computing platforms.
  • Experience with large-scale feature engineering, data pipelines, distributed storage, or petabyte-scale data processing.
  • Experience building model-serving, batch-inference, or online-inference infrastructure.
  • Experience managing public-cloud or hybrid-cloud resources and optimizing GPU costs.
  • Experience building GPU clusters or tuning distributed-training performance, or familiarity with PyTorch Distributed, CUDA, or RDMA.
  • Familiarity with AI coding tools such as Claude Code or Codex, and practical experience incorporating them into development workflows or building supporting tools.
