• Collaborate with product, UX, and engineering teams to deliver scalable, end-to-end solutions
• Ensure high performance, reliability, and responsiveness of both backend services and UI components
• Participate in code reviews, testing, and debugging to maintain high engineering standards
• Support deployment, enhancements, and ongoing optimization of the platform

Required Qualifications

• 4+ years of software development experience
• Strong hands-on experience with:
• Java
• Spring Boot / Spring Framework
• REST API development
• Experience building front-end applications with Next.js, React, or similar frameworks
• Understanding of API-driven architecture and microservices design
• Experience integrating frontend applications with backend services
• Familiarity with relational or NoSQL databases
• Experience with Git and CI/CD pipelines

Preferred Qualifications

• Familiarity with API security practices (OAuth, JWT)

What This Role Focuses On

• Transitioning a legacy operational tool into a modern, scalable platform
• Enhancing the user experience for retail/store operations
• Building robust API layers to support integrations and future extensibility
• Delivering full-stack impact across backend services and frontend interfaces

Ideal Candidate Profile
