We are seeking a Staff Backend Engineer to design and build scalable, AI-native backend services that power customer intelligence, campaign orchestration, and attribution at automotive retail scale. This role is the critical technical anchor — defining hexagonal architecture patterns, owning service boundaries, driving AI integration patterns, and setting the engineering bar for the entire team.

Key Responsibilities
- Architect Java (Spring Boot 3.x) microservices using hexagonal architecture — defining clean domain cores, port interfaces for persistence (MongoDB, PostgreSQL, Cosmos DB), and adapter implementations for Kafka, Elasticsearch, Redis/Aerospike, and external APIs.
- Own core domain models and service boundaries end-to-end: from initial hexagonal design through production operation, Kafka event contracts, and iterative enhancement.
- Build scalable,



secure REST APIs and robust Kafka-based event-driven pipelines that consume and produce events across multiple source systems.
- Design MongoDB document schemas and PostgreSQL relational schemas for high-throughput, multi-tenant workloads — with deep attention to indexing strategy, TTL, and tenant isolation patterns.
- Design Cosmos DB data models for high-throughput event and state storage — partition key strategy, consistency levels, and TTL configuration.
- Design and implement durable campaign execution workflows using Temporal.
- Establish and own AI-native integration patterns: MCP tool registration, scoring model serving contracts, LLM gateway integration, and agentic workflow design.
- Identify and resolve performance bottlenecks across services, Kafka pipelines, data layers, and Elasticsearch query performance.
- Ensure all systems meet reliability, scalability, and observability standards.
- Mentor senior, mid-level, and junior engine
