Lead Infrastructure Engineer

Lead Infrastructure Engineer (Windows/M365/Azure) Security & Operations (MSSP)

Location: Coimbatore, Tamil Nadu (Full-time)

Shift: 8:00 PM 5:00 AM IST (MT business hours alignment)

Reports To: Security Operations Manager (solid-line)

Dotted Line: CEO (United States) for platform/stack strategy, POC prioritization, and major tooling decisions

The Mission

Fountain Hills Technologies is an Arizona-based MSSP expanding our 24/7 India operations. Were seeking a senior infrastructure leader to own the standards, baselines, and automation that make our SOC/NOC faster and more reliableespecially for U.S. customers. This role sits at the intersection of infrastructure and security operations: improving telemetry/logging, hardening environments, reducing recurring issues, and serving as a hands-on escalation point for complex Windows/M365/Azure incidents.

Core Responsibilities

• Infrastructure Technical Leadership: Define and enforce technical standards across Windows/M365/Azure environments so issues are prevented, not just fixed.
• Customer Baselines & Hardening: Build repeatable baseline requirements (identity, endpoint, email, logging, monitoring) and drive adoption across customers.
• Telemetry, Logging & Integrations: Ensure security operations have the right dataimprove log collection, forwarding, reliability, and integration patterns that support detection/IR.
• Automation & Reliability: Reduce operational load through automation (PowerShell required; Python a plus), standard checks, and repeatable remediation workflows.
• L3 Escalation: Act as L3 for infrastructure and security-adjacent incidents (identity issues, email compromise support, endpoint instability, connectivity/logging gaps).
• Tooling Strategy + Modernization: Research and recommend infrastructure/security-adjacent improvements tied to measurable outcomes (stability, visibility, reduced manual work).
• POC Leadership (Internal + Customer): Lead infra-side POCs end-to-endtest plans, success criteria, operational fit, documentation, and rollout readiness (runbooks, training, support model).
• Customer-Facing Technical Support: Join technical sales and customer calls to validate designs, explain implementation approach, and guide rollout planning.
• Cross-Functional Collaboration: Partner with the Lead Security Engineer to ensure infrastructure decisions enable better detection and response (not blind spots).

Required Qualifications

• Experience: 10+ years of hands-on systems/infrastructure engineering (managed services experience strongly preferred).
• Windows & Identity Depth: Strong Windows Server/AD/GPO/DNS fundamentals plus troubleshooting at scale; strong Microsoft 365/Entra ID administration and identity troubleshooting.
• Cloud/Modern Ops Capability: Practical experience with Azure and modern endpoint/security operations requirements (logging, monitoring, baselines).
• Automation Requirement: Strong PowerShell and the ability to deliver basic scripting/automation for enrichment, validation, and remediation acceleration (Python optional but valued).
• Operational Discipline: Able to turn fixes into standards/runbooks; strong documentation habits and repeatable rollout thinking.
• Communication: Excellent written/spoken English for customer-facing technical discussions and U.S. stakeholder collaboration.
• Ownership & Judgment: Calm under pressure; makes clear recommendations and drives work through implementation.

Tools & Platforms (partial)

• Infrastructure & Networking: Palo Alto Firewalls, Cisco Meraki (Switches/APs), Datto RMM
• Security & Identity (integration awareness required): CrowdStrike (EDR/XDR), FortiMail, DNSFilter
• Data Protection: Rubrik (On-Prem & SaaS)
• Service Management: Zoho Desk

What Success Looks Like

• Fewer Repeat Issues: Recurring incidents drop due to baselines, hardening, and automation.
• Better SOC Visibility: Logging/telemetry completeness improves; fewer investigation blockers caused by missing data.
• Faster Resolution: L3 escalations resolve more quickly because standards and remediation patterns are consistent.
• Tech Stack Progress: POCs produce clear go/no-go decisions and smooth rollouts with documented support models and runbooks.
• Customer Confidence: Strong technical leadership on calls; customers see stable environments and clear guidance.
