Infrastructure Reliability Engineer

Role Overview

We are looking for a hands-on Infrastructure Reliability Engineer to improve reliability, automation, security, and operability across enterprise infrastructure—spanning cloud and on-prem/hybrid environments. This role focuses on Terraform + Ansible automation, Windows and Unix/Linux operations, observability, incident/postmortems, and strong vulnerability remediation ownership across servers, platforms, and containerized workloads.

The resources should have a minimum of 5 years' experience and the business is looking for the resources to have deep technical acumen across enterprise infrastructure.

Key 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.
• Establish sustainable patching, upgrade, and lifecycle management processes to reduce recurring findings.
• Vulnerability management tools (Qualys, Tenable, Rapid7, etc.).
• Audit and controls remediation experience - preferred.
• Ability to work across Cyber, Risk, Controls, Infrastructure, and Application teams.

Infrastructure Automation (Terraform + Ansible)

• 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).

Hybrid / Enterprise Infrastructure Operations

• 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.

Security & Vulnerability Remediation (Must-Have)

• Own vulnerability remediation workflows across OS, middleware, images, and dependencies: scanning → triage → patch/upgrade → validation → reporting.
• Support hardening standards (baseline configs, least privilege, secrets handling, access controls) and help close audit findings.

CI/CD & Release Enablement

• 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 (e.g., SonarQube, scanning steps).

Observability & Monitoring

• Build and maintain monitoring/alerting and dashboards using tools such as 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.

Reliability Engineering (SRE)

• 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.

Required 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).
