Integration Software Engineer


Fintecture is a payment infrastructure offering immediate transfer, allowing merchants to collect payments easily.

Launched in 2020, the idea was born out of a simple analysis and yet ignored by all: traditional payments are too complex for merchants and a source of uncertainty for payers.

So, we took a crazy bet: reinventing the payment ecosystem by tackling the technological architecture of payments. Our role is to bring innovative solutions to an industry monopolised by historical players.

We have grown from a team of 7 to over 80 motivated and determined talents to rewrite the history of the payments’ industry. This team has enabled us to sign some fifteen big accounts, ranging from large retail such as Auchan and Leroy Merlin, to business services such as Edenred and Groupe Up, and even tech giants, in just six months.

In 2022, we are raising a total of $29m with the objective of positioning ourselves as the leader of account-to-account payments, doubling our business-volume every two months.

Fintecture, beyond the technology, is a way of looking at the future!
