Full Stack Engineer

CASABOT is looking for a Senior / Mid Full-Stack Engineer to help build and scale the next generation of intelligent product experiences. This role is for an engineer who can move confidently across frontend, backend, integrations, and cloud infrastructure while keeping product quality, performance, and developer discipline high.

You will work on modern web applications, real-time product experiences, backend services, third-party integrations, and scalable architecture. We are looking for someone with strong hands-on engineering skills, good product sense, and the ability to work in a fast-moving environment where clarity, ownership, and execution matter.

Role Overview

As a Full-Stack Engineer at CASABOT, you will contribute to the design, development, integration, and optimization of core product capabilities. You should be comfortable building with the MERN stack, shaping frontend architecture with React / Next.js, designing backend services with Node.js / Express, and working with databases and real-time communication patterns.

This role also requires practical experience with third-party APIs, API versioning, CI/CD, Docker, AWS, logging, debugging, and collaborative engineering practices. You should be able to contribute not just code, but also structure, documentation, and sound engineering judgment.
