Linux Systems Engineer

Human Intuition. Machine Intelligence. Relentless Exploration. We're looking for a Senior Systems Engineer with 5–8 years of hands-on experience to own critical Linux infrastructure in a high-performance, low-latency trading environment.

Requirements

• 5–8 years of Linux systems engineering experience in production environments (RHEL/Rocky/CentOS strongly preferred)
• Deep, hands-on expertise with OpenShift and/or Kubernetes — cluster operations, CRI-O/container, resource management, and production troubleshooting
• Proven experience with Ceph distributed storage — OSD tuning, CRUSH maps, BlueStore, and failure domain design
• Strong consultative skills — ability to interface directly with developers and traders to translate business needs into technical infrastructure improvements
• Solid data center operations experience — server racking, cabling, firmware management, and out-of-band access (IPMI/iDRAC/iLO)
• Strong background in optimizing Linux systems for low-latency workloads — kernel tuning, CPU pinning, NUMA topology, and network stack optimization
• Experience supporting or directly working in financial services or electronic trading environments
• Sharp debugging skills across the full stack — you can go from a trading alert to a kernel trace without needing to be pointed in the right direction
• Red Hat Enterprise Linux (RHEL) certification is required

Benefits

• Competitive compensation
• 401(K) matching
• Gender-neutral parental leave
• Comprehensive medical, dental, and vision insurance
