Senior Director, IT Infrastructure and End User Experience

Cambridge, MA USA

The Senior Director, IT Infrastructure and End User Experience is a senior technology leader responsible for the strategy, design, delivery, and operation of the enterprise's corporate IT infrastructure and the end-to-end employee computing experience. This role is the accountable owner for a broad IT portfolio spanning corporate networks, endpoints, identity, audio/visual systems, print infrastructure, and the full collaboration and productivity suite—including Microsoft 365, Google Workspace, Slack, Notion, and Zoom.

Equally, this leader owns every stage of the end user technology lifecycle: onboarding, offboarding, birth-right access provisioning, service requests, helpdesk support, end-user enablement (hardware, software, accessories, training), AI enablement, and delivery of overall IT services. The goal is a secure, resilient, and modern technology environment that empowers employee productivity and business growth.

Reporting to the Chief Information and Security Officer (CISO), the Senior Director leads a multi-disciplinary team of engineers, administrators, support professionals, service providers, and manages significant operational and capital budgets. The role partners closely with Business Systems, Cloud, Security, IT/OT Convergence, GRC, HR, and other business stakeholders to deliver a frictionless, consumer-grade digital workplace.

The successful candidate will balance operational excellence with continuous innovation—driving collaboration platform modernization, automation, AI enablement for the workforce, and Zero Trust principles—while keeping employees, performance, reliability, and compliance outcomes at the center of every decision.
