Description

Onebeat is a fast-growing retail technology company helping some of the world's leading retailers make smarter inventory decisions using AI and advanced optimization. Our platform enables retailers to optimize replenishment, allocation, inventory balancing, and store operations—improving product availability while reducing excess inventory. Joining Onebeat means building software that solves real-world retail challenges at scale. Every feature you develop has a direct impact on global customers and millions of inventory decisions every day.

We're looking for a Full-Stack Application Developer to join one of our product teams and own features from technical design through production.

This is an opportunity for an engineer who enjoys building high-quality software, solving complex technical problems, and working across both frontend and backend technologies.

We will review CV`s in English only! We are looking for candidates based in Recify.
