Senior Security Client Solutions Architect – Microsoft; Remote

Who You Are

You're a Microsoft Security strategist who connects business risk, regulatory requirements, and the Microsoft security ecosystem into cohesive, outcome‑driven solutions. You are equally comfortable in executive conversations and deep architectural design sessions, translating complex security capabilities into clear, actionable road maps.

You naturally think in Zero Trust patterns and understand how identity, endpoint, cloud, data, and security operations interconnect within the Microsoft stack. You can lead discovery, shape deal strategy, and produce high‑quality client‑ready deliverables that accelerate services revenue while ensuring solutions are implementable and operationally sustainable. You operate independently, partner closely with sales and delivery teams, and mentor others to elevate Microsoft security architecture and consultative practices across the organization.

The Sr. Security CSA (Microsoft Security) leads solution strategy for complex Microsoft‑centric engagements. You will drive executive discovery, design integrated Microsoft Security architectures, and develop multi‑phase roadmaps aligned to measurable business outcomes. This role partners closely with Account Executives and practice leaders to qualify opportunities, shape deal strategy, increase services attach rates, and expand scope through cross‑sell and recurring services. You will serve as a trusted advisor to clients, an escalation point for complex designs, and a mentor to internal teams.

Must be based in the United States. Travel ranging from 40% to 80% may be required.
