Backend Developer Intern (Remote)

We’re looking for a Backend Developer Intern to join our engineering team at Credes - someone who writes clean, thoughtful backend code, understands system design at a foundational level, and operates with strong depth in AI-assisted development. This is a paid, fully remote internship with real stakes. You won’t be writing dummy CRUD APIs. You’ll be building backend systems that power real client products and in-house applications — with live users, real data, and production constraints. If you have strong Node.js fundamentals, a working knowledge of Django or FastAPI or Go, and 2–3 projects you’ve actually shipped — we want to talk. Key Responsibilities Design, develop, and maintain backend services and REST APIs for client and in-house projects Build scalable server-side applications primarily in Node.js, with Django, FastAPI, or Go as secondary stack depending on project requirements Handle database design, schema definition, query optimisation, and performance tuning across PostgreSQL, MySQL, and MongoDB Implement authentication and authorisation flows including JWT, OAuth, and role-based access control (RBAC) Integrate backend services with web and mobile frontends through well-documented APIs Use Redis for caching, session management, and performance optimisation Apply system design principles and architecture patterns to build for scale from the start Leverage AI-assisted development tools (GitHub Copilot, Cursor, Claude, etc.) effectively — and critically evaluate their outputs Debug, test, and document backend code to production-ready standards Collaborate with frontend and mobile developers to ensure seamless, reliable integrations Primary Requirements Non-Negotiable Requirements These are strict filters.
