Backend Software Engineer

How will you make our customers happy? Every feature bol's shop teams produce, whether it's a customer-facing website innovation, an in-app UX improvement, or an update across emerging shopping channels, is built on a backend environment that you help create, cultivate, and evolve. As a Software Engineer in ShopCore-BackEnd, you build and operate the backend foundation that enables dozens of teams to scale, experiment, and ship with confidence, without having to worry about what's happening under the hood. This role goes beyond writing code. You'll help shape the platform, reliability, automation, and developer experience that product teams depend on every day. Every improvement you make accelerates product teams and helps millions of customers to a better shopping experience. The biggest challenge The challenge is not building features for a single product team; it is shaping the platform that 55+ teams depend on. Behind every successful product team is a reliable, scalable, and well-operated foundation they can trust. You will help evolve that foundation by solving scalability challenges, improving engineering effectiveness and balancing software development with operational excellence.
