• Collaborate with Digital, Loyalty, CRM, MDM, Architecture, and Infrastructure teams.
• Provide technical leadership to offshore Senior Developers, Developers, and QA/Automation.
• Participate in architecture reviews, capacity planning (4M+ monthly events), and production operations.

• 10+ years backend engineering; 5+ years implementing event-driven architectures.
• Strong expertise in Java, Spring Boot, microservices, and distributed systems.
• Hands‑on experience with GKE/Kubernetes, Pub/Sub or Kafka, and cloud‑native design.

• Strong integration experience with external APIs (Mar Tech, CRM, MDM, or messaging systems).
• Understanding of IAM, secure webhook handling, and zero‑trust principles.
• Experience implementing observability frameworks across microservices.

• Experience building or operating large‑scale notification, messaging, or orchestration platforms.
• Exposure to ESPs (Listrak, Braze, Iterable, SFMC, Adobe Campaign).
• Experience with hybrid on‑prem → cloud event ingestion models.
