Job description

We are looking for a Senior Infrastructure Engineer to take ownership of our enterprise Microsoft 365 platform and supporting infrastructure. This is a hands-on engineering role focused on platform architecture, automation, reliability, modernization, and emerging AI capabilities — not primarily ticket-based administration.

The ideal candidate is a proactive engineer who can independently identify opportunities, solve complex technical problems, and turn business requirements into secure, scalable, and practical technology solutions.

Key Responsibilities

• Own the engineering, architecture, and continuous improvement of the enterprise Microsoft 365 platform.
• Design, implement, and maintain Microsoft Entra ID, Hybrid Active Directory, Group Policy, and Identity & Access Management.
• Engineer and support Exchange Online, Windows Server, Enterprise PKI, and enterprise DNS services.
• Contribute to the modernization of on-premises infrastructure toward cloud-based services.
• Develop and maintain production-grade automation, primarily using PowerShell, to reduce manual operational effort.
• Build automated monitoring, remediation, and operational workflows to improve platform reliability and efficiency.
• Identify opportunities to apply Microsoft Copilot, OpenAI, and AI agents to infrastructure operations and engineering productivity.
• Apply an SRE mindset to improve reliability, resilience, scalability, and operational efficiency.
• Troubleshoot complex infrastructure and platform issues and address recurring problems through engineering and automation.
• Translate business requirements into secure, scalable, and maintainable technical solutions.
• Take end-to-end ownership of significant infrastructure and Microsoft 365 initiatives, from architecture and design through implementation.
• Work closely with infrastructure, security, application, cloud, network, business, and senior leadership teams.

Required Skills & Experience

• Strong hands-on experience with Microsoft 365 platform engineering.
• Strong expertise in Microsoft Entra ID and Identity & Access Management.
• Strong Hybrid Active Directory architecture and engineering experience.
• Experience with Exchange Online.
• Strong PowerShell scripting and automation capabilities.
• Strong Windows Server engineering, hardening, and troubleshooting experience.
• Experience with Enterprise PKI, DNS, networking, and infrastructure security.
• Experience designing and implementing enterprise automation in production environments.
• Strong technical problem-solving and troubleshooting capabilities.
• Ability to work independently, take ownership, and drive initiatives with limited supervision.
• Strong communication skills and the ability to work effectively with both technical and non-technical stakeholders.

Preferred Skills

• Microsoft Copilot and enterprise AI experience.
• Experience with OpenAI or related enterprise AI platforms.
• Experience applying AI to infrastructure or Microsoft 365 operations.
• ServiceNow automation experience.
• AWS experience, particularly Route 53 and SES.
• ITSM/ITIL and Agile/Kanban experience.
• Experience in financial services or another regulated environment.
