For nearly two decades, we have led our industry and worked at the frontier of applying AI/ML to investment management. We have become a multibillion-dollar asset manager, and we have ambitious goals for the future.\nYour colleagues will include internationally recognized experts in artificial intelligence and machine learning research as well as highly experienced finance and technology professionals. In addition to our enriching and collegial working environment, we offer highly competitive compensation and benefits packages, technology talks by our experts, a beautiful modern office, daily catered lunches, and more.\nAs a Senior Cluster Site Reliability Engineer (SRE), you will help scale our research compute cluster to meet our growing needs, and you will leverage engineering skills to ensure high degrees of uptime, reliability, and robustness. Our research clusters are at the core of our R&D, and you will be directly responsible for keeping this key resource available and performant. Your work will provide a world-class HPC platform for researchers to focus on cutting-edge machine learning problems at scale. You will support both on-prem and cloud infrastructure, and work to provide the best experience to our technical staff. You will leverage IaC, Automation, and SRE principles to refine and hone a product that operates 24/7 to support Voleon.\nThe Cluster Operations team works on the frontline to triage and mitigate real-time operational issues. You will be an integral member of this team, solving day-to-day issues with high urgency, while also engineering systemic improvements and architectural fixes to prevent recurring issues. You will collaborate with engineering teams to develop improvements to monitoring/telemetry. You will help design and oversee operational frameworks to ensure the cluster operates within a set of rigorous SLAs.\nResponsibilities\nBe a first responder in the event of cluster outages or issues. Triage and resolve urgent issues as they arise\n\nEnsure a high degree of cluster uptime (measured in multiple nines), and define + track SLAs to quantify reliability\n\nDiagnose systemic/recurring patterns of problems, and engineer precision solutions to them in collaboration with engineering teams\n\nDevelop 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\n\nHelp software and research teams design policies around fair cluster usage, and help develop enforcement mechanisms for said policies\n\nAssist in forecasting cluster growth, and help select appropriate scale-up strategies. Help optimize operations across dimensions of cost and usability\n\nRequirements\n5+ years of experience in SRE or DevOps roles, preferably working as a senior engineer or tech lead\n\nKnowledge of HPC/batch compute frameworks (Slurm, Kueue, AWS/GCP Batch) and/or machine learning training systems (Kubeflow, MLflow, Horovod)\n\nAbility to develop scripts and utilities of moderate complexity in a common scripting language (Python, Ruby, etc.)\n\nFamiliarity with infrastructure-as-code and configuration management tools (Terraform, Ansible)\n\nExperience with cloud infrastructure (AWS or GCP)\n\nFamiliarity designing and implementing modern observability stacks (Prometheus, Grafana, Loki, ELK, OpenTelemetry)\n\nExperience with distributed storage technologies (Lustre, Ceph, S3)\n\nEmbodies a \"system engineer\" rather than \"system administrator\" mindset, thinking systematically and leveraging automation\n\nBachelor degree in computer science\n\nPreferred Qualifications\nHands-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)\n\nFamiliarity with ML frameworks (PyTorch/Tensorflow, JAX, Horovod, DeepSpeed)\n\nFamiliarity with hybrid/on-prem environments\n\nExperience with containerization (Docker, Podman, Singularity), particularly for HPC/batch compute environments\n\nExperience with HPC networking (InfiniBand, RDMA)\n\nSolid security/IAM foundations (Identity management systems, AWS/GCP IAM, Zero Trust)\n\n“Friends of Voleon” Candidate Referral Program\nIf you have a great candidate in mind for this role and would like to have the potential to earn $15,000 if your referred candidate is successfully hired and employed by The Voleon Group, please use this form to submit your referral.
