Software Engineer

JOB DESCRIPTION As a Backend Engineer on the core team, you will help build the microservices, event-driven pipelines, and database integrations that power this engine. You will work alongside senior engineers to solve complex problems around scale, concurrency, and data consistency. Who You Are You write clean, testable, and maintainable code. You are curious about system architecture and want to learn how to design for high scale. You are comfortable asking questions, admitting what you don't know, and learning new technologies quickly. You care about edge cases, error handling, and what happens when systems fail. RESPONSIBILITIES Build & Scale Backend Services: Develop robust, high-performance microservices using Java and Spring Boot to handle real-time rule evaluation and incentive calculations. Event-Driven Development: Implement consumers and producers for our event bus (e.g., Google Pub/Sub, Kafka) to handle vehicle and program updates asynchronously. Database Optimization: Write and optimize complex SQL queries, design schemas, and manage data efficiently in PostgreSQL. Batch Processing: Assist in developing and maintaining batch processing pipelines (e.g., Dataflow/Beam) to handle large-scale program rollouts and data synchronization with our data warehouse (BigQuery). Ensure Quality & Correctness: Write comprehensive unit and integration tests. Since this system handles financial incentives, you will implement idempotent operations and precise data handling to ensure 100% accuracy. Collaborate: Participate in code reviews, technical design discussions, and work closely with product managers and QA to deliver features reliably. QUALIFICATIONS 3+ years of professional experience in backend software engineering. Core Tech: Strong proficiency in Java (Java 11/17 preferred) and the Spring Boot ecosystem. API Design: Proven experience building, securing, and scaling RESTful APIs and microservices. Databases: Solid understanding of relational databases (SQL). You should know how to write efficient queries, use indexes properly, and understand database transactions. Problem Solving: Strong grasp of data structures, algorithms, and basic Java concurrency. Best Practices: Experience with Git, CI/CD pipelines, JUnit/Mockito, and clean code principles.
