What You’ll be doing

• Deliver end-to-end infrastructure setups across regions/colocations: bring-up, validation, and go-live readiness
• Own the systems side of the stack: Linux servers, OS baseline, automation, configuration, and performance tuning
• Run and improve testing/validation: connectivity checks, load/performance tests, failure testing, and readiness checklists
• Participate in investigation of complex issues and bottlenecks across layers (OS/kernel/drivers/dependencies) and drive fixes with network/hardware peers and 3rd party vendors
• Build repeatable automation and rollout playbooks (Terraform/Ansible, scripting, standards)
• Improve observability: metrics/logs, dashboards, alert tuning, and latency/performance baselines
• Strengthen operations: runbooks, incident reviews (RCA), change hygiene, and documentation
• Participate in scheduled on-call rotations to support trading infrastructure and incident response. 

What we look for in you:

• Hands-on production experience with Linux and systems troubleshooting
• Ability to debug across layers and coordinate effectively with network/hardware engineers
• Solid networking fundamentals (TCP/IP, DNS, routing basics, MTU, packet loss/jitter symptoms)
• Automation mindset: bash/Python; Terraform/Ansible experience is a plus
• Strong written and verbal communication (clear status updates and documentation)
• Passion for technology and continuous learning 

Nice-to-Have:

• Low-latency / performance tuning experience (CPU/IRQ affinity, NIC tuning, etc.). Colocation / provider coordination experience (setups, acceptance, troubleshooting)
• Time synchronization basics (NTP/PTP) and practical impact on production systems
• Interest or experience in trading / exchange / broker connectivity
