Midwest Tape's hoopla Digital is looking to expand its team to design, develop, and deliver technical solutions for the eCommerce and Product Discovery team, with a primary focus on backend services built using Java. This involves modernizing existing systems, improving scalability, and enhancing operational efficiency.
Requirements
- Strong hands-on experience designing and deploying microservices in distributed systems using Spring Boot 3 and Spring Security.

- Skilled in developing and maintaining RESTful APIs and GraphQL, with experience documenting APIs using Swagger/OpenAPI.
- Deep expertise in Apache Kafka and event-driven architectures, including building ETL-style data pipelines for integration and streaming.
- Solid understanding of relational databases, particularly PostgreSQL, with the ability to read, refactor, and optimize complex SQL; 5+ years working with NoSQL databases, especially MongoDB, including schema design, indexing, and performance tuning.
- Strong grasp of design patterns, SOLID principles, and engineering practices such as Test-Driven Development (TDD), Domain-Driven Design (DDD), and clean architecture.
- Proficient in writing unit and integration tests using JUnit, Mockito, and Spring Test frameworks, with CI/CD automation experience using GitHub Actions.
Responsibilities
- Re-architect existing PostgreSQL stored procedure logic into Java-based microservices that are scalable, testable, and easier to maintain, using a Kafka-driven, event-based ETL approach for decoupled data processing and system integration.
