Our solutions allow merchants to route dynamically a transaction to the best payment provider to optimise their conversion rate. Your main task will be to design and create or maintain micro-services within our infrastructure. Our product handles millions of transactions within a week. The API has its key part on it but the load is also on a multitude of other services.

You will work closely with our technical teams to learn about the possible technical bottle-necks.

Your role would be to lead us to new technologies that our product can benefit from.

Our product handles financial data making uptime one of our key KPIs. We expect that you will be able to work on high-availability and technically challenging programs. 

You will join a talented team of 10 engineers, Data Scientists and DevOps, that are tech-passionate, working closely with most of them. Our main goal is to ensure that we can contribute to your personal growth as an engineer.

Our team is focused on building the best payment performance tool there is. It allows merchants to better understand their online processes as well as offline payments.
