Linux Infrastructure Architect for Quantitative Research
2 days ago
We are seeking an expert Linux engineer to join our global technology infrastructure team. This is not a traditional admin or support role – instead, you will be a core enabler of quantitative research and high-performance computing (HPC) within a large-scale financial research environment.
The successful candidate will design, scale, and automate compute and storage platforms that allow researchers and portfolio managers to run advanced models and experiments.
- Design and manage quant research platforms and HPC environments.
- Research and experiment with new centralized multi-tenant clustered platforms.
- Troubleshoot complex issues across storage, OS, and networking layers.
- Build tools to improve performance, monitoring, and automation of HPC clusters.
- Drive efficiency through automation of provisioning and housekeeping.
Required Skills and Qualifications
The ideal candidate will have:
- 5+ years of engineering, deployment, and management of large-scale (250+ servers) Linux infrastructure, ideally in financial services or HPC environments.
- Expertise in distributed file systems (Lustre, GPFS) and a variety of filesystems (ZFS, XFS, ext4).
- Strong knowledge of Linux (RHEL/CentOS/Ubuntu) configuration, troubleshooting, and performance tuning.
- Familiarity with x86/AMD platforms optimized for both transaction speed and distributed parallel processing.
- Networking knowledge: 10GE/25GE, InfiniBand, RoCE, RDMA.
- Experience with Linux software RAID, hardware RAID, erasure encoding.
- Infrastructure automation skills: Terraform, Ansible, Puppet, Chef.
- Scripting: Python and Shell.
- Protocol knowledge: NFS (v4.1), CIFS, SMB, ACLs.
- Hybrid and cloud-native HPC deployment experience (AWS preferred).
- Familiarity with AWS storage services (S3, Storage Gateway, EBS).
- Knowledge of AI/ML HPC offerings on cloud platforms (AWS/GCP).
- Experience with HPC job schedulers (Slurm, Condor, Airflow, SGE).
- Hardware familiarity: HPE, Dell, Supermicro systems.
What Sets This Role Apart
This is not just a Linux admin/support role – you'll architect, engineer, and automate large-scale HPC platforms used for quantitative finance and advanced research. You'll work on mission-critical systems enabling portfolio managers and researchers to test and run complex models.
As part of our fast-paced, innovation-driven environment, you'll collaborate with experts who see infrastructure as a strategic enabler, not a back-office function.
