Junior Linux Systems Engineer

Human Intuition. Machine Intelligence. Relentless Exploration.

The Role:

Responsibilities:

• Infrastructure Lifecycle: Execute the end-to-end server lifecycle, including racking, cabling, configuring, and maintaining physical hardware in our regional data centers.
• Support OpenShift/Kubernetes: Assist in deploying, scaling, and operating OpenShift clusters; help monitor cluster health, perform upgrades, and manage basic workload scheduling.
• Maintain Ceph Storage: Monitor and administer Ceph clusters, assist with capacity management, and learn to optimize distributed storage for throughput and latency.
• Access & Security Management: Manage users, granular access controls, and security protocols. Monitor backup systems to ensure data integrity and system resilience.
• Performance Monitoring: Learn and apply basic OS-level optimizations to support latency-sensitive applications; assist senior engineers with advanced kernel tuning (NUMA, CPU pinning).
• Production Reliability: Respond to and resolve incident tickets within required SLAs. Proactively monitor complex hardware/software issues, participate in root cause analysis (RCA), and escalate critical incidents to senior team members appropriately.
• Automation Support: Write, maintain, and execute automation scripts using Ansible, Terraform, or Python to reduce manual toil across bare-metal and virtualized environments.
• User Support: Work directly with trading and development end users to troubleshoot daily issues and provide reliable infrastructure support.

You Bring:

• 1–5 years of Linux systems administration experience in production environments (RHEL/Rocky/CentOS strongly preferred).
• Foundational knowledge of containerization (Docker/Podman) with an eagerness to learn OpenShift and Kubernetes cluster operations.
• Exposure to or a strong interest in learning distributed storage systems (like Ceph) and failure domain design.
• Solid data center operations experience — server racking, cabling, hardware troubleshooting, and out-of-band access (IPMI/iDRAC/iLO).
• Solid troubleshooting skills — you are comfortable diving into system logs, monitoring tools, and basic network stacks to isolate issues.
• Clear communication skills — ability to interface directly with developers and traders to resolve technical issues promptly.
• A strong interest in electronic trading environments and low-latency systems.
• Red Hat Certified System Administrator (RHCSA) certification is required; working toward or holding a Red Hat Certified Engineer (RHCE) certification is considered a strong bonus.
• You are a proactive, naturally curious person who values transparent communication and thrives in a mentorship-rich environment.
