Why Join Us

At Cloudfide, we engineer solutions where data truly becomes an accelerator for innovation. We build and evolve large-scale Big Data and cloud-native platforms for global clients, including leaders in retail and the Fortune 500. We process massive, complex datasets, operate fully in the cloud ecosystem, and work with the latest technologies, including AI, ML, MLOps, and modern data architectures.

Our projects have measurable, real-world impact, from enhancing customer experiences at scale to empowering data-driven decision-making in high-visibility global organizations. As we continue to grow, you'll have the opportunity to shape solutions, mentor others, drive architecture decisions, and take ownership of strategic initiatives.

Opportunity Overview

As a Fullstack Engineer, you will build a services support portal powered by a conversational AI assistant. Your goal will be to deliver a polished, secure, accessible, and responsive application where users and support agents can easily find knowledge and escalate to human support when needed.

Expect an AI-forward environment where you'll work across the full stack, from React interfaces to Python services and agentic AI capabilities. You'll join a team of passionate engineers who value technical excellence, collaboration, and continuous growth.
