What We Offer
At Convverge, we build business‑level solutions using Microsoft technology to solve complex problems for our clients.We’re a close‑knitted, high‑trust team that values technical quality, ownership, and practical problem solving. Our people are trusted to make good decisions, take accountability for outcomes, and work collaboratively across disciplines.We’re looking to add senior technical depth to our team through a fractional role that combines hands‑on engineering, solution design, technical leadership, and knowledge transfer.About the Role
Convverge is looking for an experienced Fractional Senior Infrastructure & Cloud Engineer to provide senior‑level technical expertise across our client environments.This is a hands‑on fractional role designed to complement our existing technical team by providing deeper expertise across Microsoft cloud, infrastructure, networking, security, and complex technical troubleshooting.You’ll step in where senior technical depth is required, whether that means resolving a difficult Tier 3 escalation, designing an Azure Virtual Desktop environment, reviewing a client’s security posture, supporting a migration, or helping determine the right technical approach to a complex infrastructure problem.This is not a traditional help desk position. Your focus will be on the problems and projects where experience, judgment, and technical depth matter most.Just as importantly, we want this role to strengthen the capability of the team around you. A key part of the mandate is to solve, document, teach, and standardize so that knowledge is shared rather than concentrated.What You’ll Do
