Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.
Expect deep dives on distributed systems, Kubernetes/cloud ops, incident response, and payment-adjacent reliability. Prepare stories on SLOs, safe rollouts, and debugging production issues. Be ready to discuss how platform choices support merchant card acceptance and banking features.

As a Senior Platform Engineer at SumUp you would typically own shared infrastructure that keeps payment and merchant services reliable: design and operate platform APIs, CI/CD, observability, and capacity for card-reader and banking backends; partner with product and security on releases; and harden systems that process merchant transactions at scale.
The listing marks remote as off; expect Berlin-based work.
Merchant card readers, online payments, and related business banking products.
