The Position

The Sr. Infrastructure Operations Engineer will work as part of a dynamic team to provide high quality engineering, implementation, and support across all areas of the Windows platform, virtualization, storage, SQL Server, and cloud infrastructure — both on premises and in Azure.

This role serves as the senior technical escalation point for the Infrastructure Operations team: the engineer other engineers turn to when an incident exceeds the team’s depth, and the person accountable for the design, resilience, and documented recoverability of the firm’s virtualization, storage, SQL, and cloud platforms. This role provides expert guidance during complex incidents that exceed the team's standard support capabilities.

This role is also the firm’s designated Operations SQL SME, as defined in the SQL Responsibilities Rider to the Infrastructure Operating Model Charter and provides technical leadership for SQL Server operational support, availability, performance, maintenance, and recovery.

This individual must be a great communicator, work well within a team, and be a self-starter able to own and independently lead projects from planning through completion.

Critically, this individual is to strengthen the overall capability of the Infrastructure Operations team by eliminating single points of failure. This includes creating and maintaining high-quality operational documentation, developing repeatable procedures that other engineers can confidently execute, and actively cross-training teammates. The objective is to build a resilient, knowledge-sharing organization where critical expertise is institutionalized rather than dependent on any one individual. Deep expertise held privately by one person is expressly not the goal of this role.

• Primary owner — Monitoring: SolarWinds — node coverage accuracy, alert tuning, and reduction of alert noise so that alerts are trusted and actioned.

• Primary owner — Enterprise application certificates: full lifecycle management, a maintained renewal calendar, and prevention of expiry-driven outages.

• Secondary owner: Active Directory and Exchange On-Premises - (on-premises), providing depth behind the existing primary owners.

• Escalation point: serve as the senior technical escalation for the Infrastructure Operations team; take ownership of major incidents, drive root cause to closure, and publish a written RCA.

• Strong hands-on experience with Microsoft-driven server OS technologies Windows Server 2012/2016/2019/2022, including in-place upgrades and failover-cluster methodologies (a Windows Server 2012 end-of-life refresh, including 14 SQL cluster nodes, is currently in flight).

• Hands-on experience with Azure, PaaS, IaaS, and workload migrations to Azure — required.
