Full Stack Engineer

About StockSaver

StockSaver is the hungarian branch of JLI Trading Limited, which is the technology-led company behind Jobalots.com and BargainFox.com, two of Europe’s fastest-growing e-commerce platforms. With millions of monthly users, we’re expanding our Budapest tech team to support ongoing growth, innovation, and platform scaling, which means developing further our existing platforms and creating new, green-field e-commerce platforms as well.

Role Overview

We’re looking for a mid-level Full-Stack Engineer with experience in Laravel (PHP) or similar backend technology and experience in React to join our core platform team. You’ll work on high-performance, production-grade systems, directly supporting e-commerce features such as checkout, payments, product catalogues, and customer account flows.

This role is ideal for someone who thrives in high-traffic environments, has a strong grasp of back-end architecture and optimisation, takes pride in clean, testable code, and is not afraid to try out new technologies.

Our team is relatively small and new, therefore you’ll have a huge impact on the way of work and team’s culture, while you will also provide a lot of impact to the products we’re developing. Therefore, we’re looking for someone who likes to take on big ownership and responsibility.
