Job Description

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.

Key Responsibilities

Security & Vulnerability Remediation

• 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.

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 (VMware or equivalent), networking (DNS, routing, VPNs, proxies), load balancers, and security controls.
• Partner with application teams to ensure infrastructure supports scalable, reliable application delivery.

CI/CD, Observability & Reliability (SRE)

• Implement and support CI/CD automation (Jenkins, Spinnaker, Cloud Deployment) and enable safe release patterns (blue/green, canary, automated rollback).
• Build and maintain monitoring/alerting dashboards using Prometheus, Grafana, Dynatrace, and Splunk.
• Improve MTTR through better telemetry and define/drive reliability outcomes using SLIs/SLOs.

Must-Have Skills

• 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 estates.
• Experience supporting enterprise infrastructure areas (compute, network, storage, load balancing, security controls).
• Demonstrated experience with vulnerability remediation (scanning, triage, patching, and verification).
• Hands-on with vulnerability management tools (Qualys, Tenable, Rapid7, etc.).
• Audit and controls remediation experience across Cyber, Risk, Controls, Infrastructure, and Application teams.
• Observability tooling: Prometheus, Grafana, Dynatrace, Splunk, and cloud-native monitoring.

Required Qualifications

• 13+ years of professional experience in SRE, DevOps, Infrastructure Engineering, or 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 (actual patching and verification).

Preferred Qualifications

• Prior EX-JPMC experience required.
• Audit and controls remediation experience.
• Experience with containerized workloads and cloud-native infrastructure.
