About the job

Prox is a fast-growing grocery savings startup helping shoppers save money by making smarter grocery decisions. We’re building tools that make it easier for consumers to compare prices, discover deals, optimize baskets, and save on the products they already buy.

We’re looking for two unpaid Software Engineering Interns to join our mobile app team and help improve the Prox app experience.

These are hands-on roles for students or early-career builders who want real startup experience working on a live consumer product.

About the Roles
