Backend Developer Intern

About Onified.ai
Onified.ai is building an Enterprise Resource Intelligence platform for manufacturers, with 50+ integrated applications spanning business and manufacturing operations.
We are looking for a Backend Developer Intern who wants to understand what happens behind those applications, like APIs, business logic, data, security, integrations and distributed systems.
You will write code that becomes part of live software, not spend six months doing training exercises.
What you will work on
Build and improve backend services and APIs
Implement enterprise business logic and workflows
Work with relational databases and data models
Build service-to-service integrations
Work with authentication, authorization and multi-tenant systems
Write tests and debug application behaviour
Investigate performance and reliability issues
Participate in code reviews
Learn how production SaaS systems are designed and operated
What we are looking for
Students who can commit full-time for six months, and 2026 graduates, from CS, IT, Engineering or related fields
Strong programming fundamentals
Understanding of object-oriented programming
Basic understanding of REST APIs
Basic SQL/database knowledge
Familiarity with data structures
Curiosity about how systems work beyond the UI
Willingness to debug rather than give up when something breaks
Good to have
Java, Spring Boot, Python, FastAPI, PostgreSQL, Redis, Kafka, Docker, Git or substantial backend projects.
Knowing our entire stack is not a requirement.
