About Numeral

Numeral is a payment technology provider that enables fintechs, payment services providers, and banks to launch new products, expand geographically, comply with payment regulations, and scale their operations with Numeral's cloud-native, API-first payments platform.

We develop and run direct integrations with a network of 30+ partner banks (including BNP Paribas, Barclays, Citi, HSBC, Banking Circle, LHV…) that can all be accessed through a single API, webhooks, and dashboard.

Customers include leading and up-and-coming fintechs like Spendesk, Swile, Alma, WorldFirst, Argentex, Deblock, and 20+ others. We have processed more than 4m payments since our first payment in 2023 and will process more than 10m payments over the next 12 months.

Founded in July 2021, Numeral has been acquired by leading core banking system provider Mambu in December 2024. Mambu’s composable core banking system complements Numeral’s API-first payments platform perfectly. Together, we are poised for hyper-growth, serving both Mambu and non-Mambu customers globally, challenging industry giants like FIS, Bottomline, and Volante, and delivering an even greater impact across our ecosystem.

This acquisition marks an exciting new chapter for Numeral. To support this growth, we are hiring across teams to scale our organisation and continue delivering exceptional customer value.

The role

As a Solutions Engineer at Numeral, you will play a critical role in supporting the entire sales cycle, from lead creation to deal closing, working alongside Account Executives to ensure prospects fully understand the value of Numeral’s solutions.
