Core Responsibilities
Defines and owns the technical architecture for CSPM tooling, automation platforms, and integration frameworks - ensuring they scale reliably across thousands of cloud accounts and multiple business units.
Designs system-level patterns (event-driven pipelines, API contracts, data models) that other engineers build on - establishing the foundational approach for how security findings flow from detection through prioritization to remediation.
Drives architectural decisions on platform extensibility, service boundaries, and data ownership - balancing near-term delivery against long-term maintainability as the program grows.

Leads technical design reviews and mentors engineers on the team - raising the bar on code quality, system thinking, and operational readiness.
Shapes the technical roadmap for AI-assisted security capabilities - evaluating where machine learning and LLM-based automation can meaningfully reduce risk or operational burden, and architecting the systems to deliver them.
