• Lead design and rollout of a horizontally scalable, real-time customer segmentation engine integrating behavioral and profile data.
• Build unified customer profile infrastructure consolidating multi-source data with real-time identity stitching and consent management.
• Collaborate with data science teams to integrate AI/ML models into production workflows, including feature stores, model deployment, and inference orchestration.
• Implement proactive monitoring, alerting, and observability (using tools like NewRelic, Sentry, CloudWatch) for operational excellence.
• Mentor and guide engineering leads and teams in architectural best practices, cloud-native design, and scalable system development.
• Partner with product managers and GTM teams to align architectural decisions with business goals and global rollout strategies.
• Own system maintenance strategies, SLAs, fault tolerance, disaster recovery, and cost optimization initiatives.
• Develop and maintain comprehensive architectural documentation and roadmap to support product growth.

Required Qualifications
