We are looking for a strong backend developer with around 5+ years of experience who wants more ownership, more technical influence, and room to grow within a fast-scaling SaaS company. The role This is a backend role with real impact. You will help design, build, and improve product features used by leading retail brands, working closely with Product, Engineering, Customer Success, and Support. You will not just implement tickets.
