About the role
The Lean Store team owns some of Lean's most revenue-critical and compliance-sensitive infrastructure - from payouts and billing to the regulatory ledger underpinning ADGM and SwiftX growth. As a Senior Software Engineer on this squad, you'll take full ownership of core systems, drive delivery on committed integrations, and ensure the reliability of infrastructure that processes millions in transactions. This is a hands-on execution role for an engineer who thrives on owning domains end-to-end.
About Lean
Lean is the leading financial infrastructure provider in the Middle East. We power some of the region's largest companies with APIs that enable payments, account verification, financial data access, and other critical financial infrastructure.
What started as the region's pioneering Open Banking platform and quickly became the de facto leader in account aggregation and payment initiation in the region is now becoming something bigger: a multi-product infrastructure company powering payments, data, and lending across MENA.
We've processed billions of dollars in transactions. We're trusted by 350+ clients - from Binance and Careem to Etisalat - and backed by General Catalyst, Sequoia, and Shorooq. Our $67.5M Series B was just the beginning. We're expanding into new markets, opening offices, acquiring businesses, and building capabilities that didn't exist here before.
