You won't be handed a finished program. You will design it. Working at the intersection of security engineering, enterprise architecture, and business strategy, you will establish the frameworks, reference architectures, and technical standards that govern how AlphaSense builds and operates its technology environment securely at scale. This role requires deep technical expertise paired with the ability to influence executive stakeholders, shape cross-functional programs, and operate as a force multiplier across Security Operations, Integrated IT, Information Engineering, and the business. At the Staff level, you will: Own the architecture: Define and maintain the enterprise security architecture across Zero Trust, identity, network, endpoint, SaaS, infrastructure, mobile, and OT domains. Set the standard: Author and govern security architecture principles, reference designs, and technical standards adopted across the organization. Lead without authority: Drive alignment across Security Operations, Corporate Technology, Information Engineering, and Integrated IT teams through technical credibility and structured decision-making. Anticipate risk: Identify architectural gaps and emerging threat vectors before they become incidents, and prescribe remediation roadmaps. Accelerate programs: Provide architecture leadership for strategic security initiatives including Zero Trust maturity, identity consolidation, SaaS governance, and device trust. Responsibilities Zero Trust & Network Security Architecture Define and own the Zero Trust and Device Trust architecture strategy, including network segmentation, ZTNA policy design, and enforcement model across corporate and remote environments.

Design device trust and certificate-based authentication frameworks integrating MDM (Kandji, Intune), Okta FastPass, TPM/Secure Enclave, and hardware-bound credentials. Define role-based access control (RBAC) architecture and Joiner-Mover-Leaver (JML) automation patterns for consistent enforcement across 200+ enterprise applications.
