🇵🇱 eCommerce Platform Engineer

About the role:

We’re looking for a Platform Engineer whose work will shape the backbone of our product ecosystem. This role goes far beyond building e-commerce plugins — it’s about designing and evolving a scalable, event-driven platform that reliably processes, stores, and exposes data coming from thousands of connected stores.

You’ll work on integrations with leading e-commerce platforms (such as Shopify, Shoper, and others), but plugins are only the entry point. The real impact comes from what happens next: how events are ingested, processed, persisted, and made available across our system in a way that is scalable, reliable, and ready for future product growth.

We move fast, value ownership, and expect our platform to keep up. You’ll take part in architectural decisions, build core platform components, and continuously improve how our integration layer and internal systems work together. Our company brings together around 180 people, including approximately a 25-person product and engineering team. You’ll be working closely with our two eCommerce platform engineers to continuously improve the platform.
