The Role
We are looking for a Mid-Level Backend Developer to join our Product Development team and strengthen one of our client project teams through February 2027.
You will work on backend systems for a modern digital product, building APIs, services, database models, integrations, and business logic using Java and Spring Boot.
You will collaborate closely with other backend developers, frontend engineers, QA engineers, DevOps, Technical Product Managers, designers, and client-side stakeholders.
We are looking for someone who already has solid professional experience and can independently deliver backend features while knowing when to ask questions, challenge assumptions, and involve other team members.
This is not a role where you simply close tickets. We value developers who understand the broader context of what they are building, communicate dependencies early, care about code quality, and take responsibility for getting their work properly tested and delivered.
What You'll Do
- Backend Development: Write clean, maintainable, testable, and efficient Java code using Spring Boot and modern backend engineering practices.
