Role Overview

We are seeking a skilled and motivated Linux Systems Engineer to join our Systems Engineering team. This is a pivotal role responsible for designing, implementing, and maintaining enterprise-grade Linux infrastructure with a strong focus on automation, security compliance, and operational excellence. The ideal candidate brings deep technical expertise in Red Hat Enterprise Linux (RHEL) ecosystems and modern automation tooling, with a passion for building scalable, repeatable, and secure infrastructure solutions.

Responsibilities

Infrastructure and Systems Engineering

• Design, deploy, configure, and maintain Red Hat Enterprise Linux (RHEL) systems across development, staging, and production environments

• Manage and optimize server infrastructure to ensure high availability, performance, and reliability

• Establish and enforce OS baseline standards and configuration management policies across the enterprise

• Lead efforts in environment normalization — ensuring consistency, compliance, and standardization across all Linux systems

• Participate in capacity planning, performance tuning, and infrastructure lifecycle management

Automation and Tooling

• Develop, maintain, and expand Ansible playbooks, roles, and collections to automate repetitive operational tasks

• Administer and optimize Ansible AWX for enterprise-wide automation workflows at scale

• Manage and administer Red Hat Satellite for content lifecycle management, host registration, patch management, and provisioning

• Leverage AI-assisted tools and platforms to enhance operational efficiency, anomaly detection, predictive maintenance, and intelligent automation workflows

• Build and maintain automation pipelines for scaling security patching, OS updates, and compliance remediation

• Contribute to Infrastructure as Code (IaC) practices and version-controlled automation repositories

Security and Compliance

• Own and drive the automated security patching lifecycle — from vulnerability identification through patch testing, deployment, and validation

• Ensure systems maintain compliance with internal security policies, CIS benchmarks, DISA STIGs, or other applicable frameworks

• Collaborate with the Security team to remediate vulnerabilities and implement hardening standards at scale

• Monitor and respond to CVEs and security advisories, coordinating timely patching across all managed systems

• Implement and maintain role-based access controls (RBAC), audit logging, and system integrity monitoring

Low-Latency/High-Performance Environments (Preferred)

• Support infrastructure requirements for high-frequency trading (HFT) or low-latency financial applications, including real-time kernel configurations and interrupt handling

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

Collaboration and Continuous Improvement

• 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

Your Profile

• 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 AWX / 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

• Postfix, Apache, Tomcat, OpenLDAP / Active Directory / MySQL / MariaDB 

• Dell / HP / Cisco UCS 

• Scripting in Shell, Perl, Python

• Virtualization Hypervisors Ovirt, RedHat KVM, VMWare

• Monitoring tools (e.g., ITRS, Spectrum, Munin, etc.) 

• EMC, Hitachi SAN Storage

• Cisco SAN switches 

Preferred Qualifications

• 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

Nice to Have

• 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)

Reporting Structure

This role reports to the Systems Engineering Team Lead and works in close collaboration with cross-functional teams including Security, DevOps, Networking, and Application Engineering.
