We believe interns shouldn’t work on “toy projects.” At Luffu, you’ll ship real code to production.

What You’ll Do

As a Java Backend Intern, you will:

• Contribute to production-level backend systems
• Design and implement gRPC APIs and microservices
• Work with real databases and distributed systems
• Write clean, testable, maintainable Java code
• Participate in architecture and code review discussions
• Debug, optimize, and improve performance of live systems
• Collaborate closely with mobile and design teams

You won’t just observe, you’ll build.

What We’re Looking For

• Strong fundamentals in Java
• Understanding of OOP, data structures, and algorithms
• Basic knowledge of gRPC APIs and SQL/NoSQL databases
• Interest in scalable systems and clean architecture
• Eagerness to learn and take ownership
• Strong problem-solving mindset

Bonus points for:

• Experience with Docker, cloud platforms, or microservices
• Familiarity with Spring / Spring Boot
• Previous personal or academic backend projects

What You’ll Gain

• Hands-on experience building real production systems
• Exposure to startup engineering culture
• Mentorship from experienced backend engineers
• Understanding of how systems scale from 0 to 1
