Note: The job is a remote job and is open to candidates in USA. The Voleon Group is a technology company that applies state-of-the-art machine learning techniques to real-world problems in finance. As a Senior Cluster Site Reliability Engineer, you will be responsible for scaling the research compute cluster, ensuring high uptime and reliability, and collaborating with engineering teams to improve monitoring and operational frameworks.
Responsibilities
- Be a first responder in the event of cluster outages or issues. Triage and resolve urgent issues as they arise
- Ensure a high degree of cluster uptime (measured in multiple nines), and define + track SLAs to quantify reliability
- Diagnose systemic/recurring patterns of problems, and engineer precision solutions to them in collaboration with engineering teams
- Develop robust metrics and observability for cluster health and use those metrics to inform your work. Build out custom observability mechanisms when off-the-shelf ones won't do
- Help software and research teams design policies around fair cluster usage, and help develop enforcement mechanisms for said policies
- Assist in forecasting cluster growth, and help select appropriate scale-up strategies. Help optimize operations across dimensions of cost and usability
Skills
- 5+ years of experience in SRE or DevOps roles, preferably working as a senior engineer or tech lead
- Knowledge of HPC/batch compute frameworks (Slurm, Kueue, AWS/GCP Batch) and/or machine learning training systems (Kubeflow, MLflow, Horovod)
- Ability to develop scripts and utilities of moderate complexity in a common scripting language (Python, Ruby, etc.)
- Familiarity with infrastructure-as-code and configuration management tools (Terraform, Ansible)
- Experience with cloud infrastructure (AWS or GCP)
- Familiarity designing and implementing modern observability stacks (Prometheus, Grafana, Loki, ELK, OpenTelemetry)
- Experience with distributed storage technologies (Lustre, Ceph, S3)
- Embodies a 'system engineer' rather than 'system administrator' mindset, thinking systematically and leveraging automation
- Bachelor degree in computer science
- Hands-on experience with HPC frameworks (Slurm, Grid Engine) and Kubernetes-based job orchestrators (Airflow, Kueue, Kubeflow Pipelines), along with other distributed computing frameworks (Ray, Modin, Dask, Spark)
- Familiarity with ML frameworks (PyTorch/Tensorflow, JAX, Horovod, DeepSpeed)
- Familiarity with hybrid/on-prem environments
- Experience with containerization (Docker, Podman, Singularity), particularly for HPC/batch compute environments
- Experience with HPC networking (InfiniBand, RDMA)
- Solid security/IAM foundations (Identity management systems, AWS/GCP IAM, Zero Trust)
