• Collaborate with application and network teams to minimize latency and maximize throughput in performance-critical environments

• Work closely with the SE Team Lead, DevOps, Security, and Application teams to align infrastructure with organizational goals
• Document systems, processes, runbooks, and automation workflows thoroughly
• Mentor junior engineers and contribute to team knowledge sharing
• Evaluate and recommend emerging tools, technologies, and AI-driven solutions to continuously improve operational capabilities
• Participate in on-call rotation and incident response as required

• 5+ years of hands-on Linux systems engineering experience (mid-level) or 7+ years (senior level)
• Deep expertise in Red Hat Enterprise Linux (RHEL 7/8/9) installation, configuration, administration, and troubleshooting
• Proficiency with Ansible; writing and maintaining complex playbooks, roles, and modules
• Hands-on experience with Ansible/Red Hat Ansible Automation Platform (AAP)
• Demonstrated experience with Red Hat Satellite; content views, lifecycle environments, activation keys, remote execution, and patch management
• Strong understanding of Linux security fundamentals; SELinux, firewalld, PAM, sudoers, auditd, and system hardening
• Experience building and managing automated patching and OS update workflows
• Solid understanding of networking concepts; TCP/IP, DNS, NFS, bonding/teaming, VLANs
• Excellent troubleshooting, analytical, and problem-solving skills
• Strong written and verbal communication skills with the ability to document technical processes clearly

The technology integral to our operating environments include:

• Red Hat Enterprise Linux (Microsoft Windows is a plus)
• Automation tools and configuration management (Ansible)
• Clustering (RedHat Cluster), Virtual IP management

• EMC, Hitachi SAN Storage
• Cisco SAN switches

• Experience in low-latency or high-frequency trading (HFT) environments
• Familiarity with real-time kernel (RT kernel) configuration and tuning
• Knowledge of DPDK, SR-IOV, CPU pinning, NUMA tuning, and huge pages
• Experience with AI/ML-assisted operations tools (e.g., Red Hat Insights, AIOps platforms, predictive analytics tools)
• Familiarity with Red Hat OpenShift or containerized workloads (Docker)
• Experience with BeyondTrust, HashiCorp Vault, CyberArk, or similar secrets management solutions
• Knowledge of ITIL practices and change management processes
• Red Hat certifications: RHCSA, RHCE, RHCA, or equivalent
• Experience with monitoring and observability tools such as Prometheus, Grafana, Zabbix, or Splunk
• Exposure to cloud platforms (AWS, Azure, GCP) and hybrid infrastructure models

• Experience with FIX protocol infrastructure or financial market data systems
• Familiarity with compliance frameworks such as PCI-DSS, SOX, or NIST
• Contributions to open-source projects or internal tooling initiatives
• Experience with ticketing and ITSM platforms (Jira)
