Seven Red Lines  is looking for a  Mid-Senior Backend Engineer  to join the  core engineering team of a fast-growing Amsterdam startup  in the e-commerce payments space. 

The company manages disputes and chargebacks end-to-end for online merchants, integrating with e-commerce platforms, payment providers, fulfillment systems, and customer-support tools to collect evidence and resolve cases with payment providers and card networks.

- Own your work end-to-end, from design through deployment, in a modern GCP environment
