About the Role
This is a senior, customer-facing technical role for a seasoned Microsoft Teams specialist with deep expertise in voice architecture, telephony, and Unified Communications. As Teams Voice Customer Engineer, you will work directly with enterprise clients to design, deploy, optimise, and troubleshoot Microsoft Teams environments — with a particular focus on Teams Telephony, Direct Routing, PSTN configurations, and enterprise voice infrastructure.
You will deliver across a portfolio of Microsoft-aligned engagements including Teams Workshops, Pilots, Activations, and Optimisation projects — as well as Teams Apps engagements. This role demands a rare combination of deep technical mastery and polished client communication — the ability to architect complex voice solutions and present them confidently to both engineering teams and executive stakeholders. If you are a UC specialist who thrives at the intersection of technology and customer success, this role was built for you.
