• Design the unified communications architecture for member engagement at scale with compliance-grade correctness.
• Define the evaluation strategy and drive quality, reliability, safety, and observability of AI-driven workflows in a regulated financial environment.
• Lead cross-organizational platform convergence - shared architectural primitives across organizations with different stacks and competing priorities.
• Establish operational integrity standards: automated verification, reconciliation mechanisms, and self-healing infrastructure that prove these platforms are correct.

• Build engineering culture: rigorous design reviews, clear standards, incident-to-prevention feedback loops, and mentoring senior engineers into technical leaders.

Requirements

• Experience building marketing, advertising, or communications platforms - multi-tenant or consumer-facing at scale.
• Experience handling data at scale: event processing, storage, and querying for hundreds of millions of events and attributes per day.
• Experience building production AI agents or LLM-powered platforms - orchestration, evals, retrieval/grounding (RAG), and guardrails for regulated environments.
• Experience in financial services or regulated industries where compliance and data integrity are architectural requirements.
