Back End Java Developer

Job Description

We are looking for two Back-End Java Developers to support a critical system modernization effort. The overall architecture has been built out, and now it’s time to bring in skilled developers to execute. This is a long-term contract role ideal for developers who thrive in heads-down coding environments and like working on tangible outcomes. You’ll be working directly with the Engineering Lead on decomposing legacy systems, building new microservices, and streamlining data processes.

Project Scope:

Modernizing how Client Information IDs (CIF IDs) are managed and used across multiple systems

Current architecture leverages CIF IDs across 12+ applications, but these will be deprecated by end of 2025

New system will assign separate IDs for teams like Sales, Marketing, etc., with all records centralized in the EKM (Enterprise Knowledge Management system)

This is a cleanup and automation-heavy project — old systems must be decomposed, new IDs integrated, and data flows automated

Day-to-Day Responsibilities:

Develop and maintain Spring Boot microservices as part of the ID migration and automation process

Integrate new system identifiers into multiple internal applications

Replace and decommission existing logic tied to legacy CIF IDs

Create and optimize API endpoints to support cross-functional data operations

Work closely with the Engineering Lead to interpret technical requirements and turn them into production-ready code

Participate in unit testing, code reviews, and production deployment processes

Debug and resolve back-end performance or integration issues as they arise

Must-Have Skills:

5–10 years of Java development experience, focused on back-end systems

Strong expertise in Spring Boot – this is critical

Familiarity with service-based architecture and distributed systems

Experience in system integration, data mapping, and refactoring legacy code

Ability to work independently – you’ll need to gather requirements from the engineering lead and take ownership of execution

Experience automating backend processes and data migration

Qualifying Questions:

Can you describe a recent project where you had to pick up requirements from a tech lead and independently deliver the solution?

What’s your experience using Spring Boot to build or refactor microservices?

Have you worked on system modernization efforts or decommissioning legacy components in the past?

How do you approach identifying downstream impacts when refactoring shared service code?

Nice to Have:

Familiarity with ID/data management in enterprise environments

Knowledge of EKM or similar centralized knowledge/data stores

Experience working in environments with marketing/sales integration platforms
