Application Security Engineer

About Verto

At Verto, we're on a mission to democratise global finance and empower businesses in Emerging Markets to reach the world. Founded by British-Nigerian entrepreneurs Ola Oyetayo and Anthony Oduu, our roots in Africa provided a firsthand understanding of the significant challenges businesses face with cross-border payments, ranging from illiquid currencies and high fees to slow transactions. This deep-rooted insight is why Africa remains a core focus, as we're committed to bridging the gap between emerging and developed markets and fostering global economic growth.

What started as an FX solution for the Nigerian Naira has evolved into a market-leading platform, enabling thousands of businesses to seamlessly transfer billions of dollars annually. We believe that where you do business shouldn't determine your success or ability to scale. We're creating equal access to the easy payment and liquidity solutions that are already a given in developed markets.

We're not alone in realising this crucial need; we're backed by world-class investors including Y-Combinator, Quona, and MEVP. With Verto receiving the Milken-Motsepe Prize, appearing on CNBCs list of fastest growing UK companies, the Deloitte Fast 50 and Sifted's fastest-growing UK tech companies, we are building a seamless cross-border payment future. Join us as we continue to grow and transform global finance.
