Job summary

Enexus Global Inc. is seeking a hands-on Infrastructure Reliability Engineer to strengthen enterprise infrastructure across cloud and on-prem/hybrid environments.

You will own automation via Terraform and Ansible, manage Windows and Unix/Linux operations, and improve observability and incident response. You will collaborate with Cybersecurity, Infrastructure, and Application Development teams to remediate vulnerabilities at scale, implement patching lifecycles, and drive reliable delivery of

Qualifications

• Strong experience in SRE / DevOps / Infrastructure Engineering / Production Operations.
• Proven hands-on automation with Terraform and Ansible in real production environments.
• Strong administration and troubleshooting across Windows and Unix/Linux.
• Experience supporting enterprise infrastructure areas (compute, network, storage, load balancing, security controls).
• Practical incident management experience (on-call, RCA/postmortems, operational improvements).
• Demonstrated experience with vulnerability remediation (not just monitoring-actual patching and verification).

Responsibilities

• Lead remediation of infrastructure vulnerabilities across Windows, Linux, middleware, and supporting Frontier AI platform components.
• Drive closure of control findings, audit items, and cyber remediation commitments within agreed timelines.
• Partner with Cybersecurity, Infrastructure, and Application Development teams to identify, prioritize, and remediate vulnerabilities at scale.

• Vulnerability management tools (Qualys, Tenable, Rapid7, etc. )
• Audit and controls remediation experience - preferred
• Ability to work across Cyber, Risk, Controls, Infrastructure, and Application teams.
• Build and maintain Infrastructure as Code using Terraform across cloud and/or virtualized environments.
• Automate configuration, provisioning, patching, and deployments using Ansible across Linux/Unix and Windows estates.
• Standardize environments (dev/test/stage/prod), build reusable modules/playbooks, and enforce configuration consistency (prevent drift).
• Operate and troubleshoot infrastructure components end-to-end, including: Compute (VMs/servers), virtualization platforms (e.g., VMware or equivalent), Networking (DNS, routing, VPNs, proxies), load balancers, firewalls/security controls.
• Partner with application teams to ensure infrastructure supports scalable, reliable application delivery.
• Own vulnerability remediation workflows across OS, middleware, images, and dependencies: triage, patch/upgrade validation reporting.
• Support hardening standards (baseline configs, least privilege, secrets handling, access controls) and help close audit findings.
• Implement and support CI/CD automation (e.g., Jenkins, Spinnaker, Cloud Deployment ) to improve release reliability.
• Enable safe release patterns (blue/green, canary, automated rollback), and enforce quality/security gates (SonarQube, scanning steps).
• Build and maintain monitoring/alerting and dashboards using Prometheus, Grafana, Dynatrace, Splunk, and cloud-native monitoring where relevant.
• Improve MTTR through better telemetry (metrics/logs/traces), service dashboards, and well-defined escalation paths.
• Define and drive reliability outcomes (availability, latency, resilience, recoverability) using SLIs/SLOs where applicable.
• Reduce alert fatigue by tuning alerts, improving signal-to-noise, and maintaining actionable runbooks.
