JobType: full time

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
