Lean is the leading financial infrastructure provider in the Middle East. We power some of the region’s most ambitious companies. What started as the region’s pioneering Open Banking platform quickly became the de facto leader. We’ve processed billions of dollars in transactions. We’re trusted by 350+ clients – from Binance and other global names to the region’s largest banks and fintechs.

About the role: The Lean Store team owns some of Lean’s most revenue-critical and compliance-sensitive infrastructure. We are looking for a Senior Software Engineer to join the Store team (banking-as-a-service) and own the core ledger functionality underpinning the SwiftX compliance use case and ADGM scaling, the billing system end to end, the Mal integration, and payouts infrastructure.

What you’ll own: Build and maintain core ledger functionality that underpins Lean’s SwiftX compliance use case and regional expansion; own the billing system end-to-end – its reliability, maintenance, and ongoing evolution; deliver on the Mal integration, a strategically committed new integration with direct revenue implications; cover ongoing payouts infrastructure – incident response, client features, and DC-related work – ensuring SLA adherence; drive stability, performance, and scalability improvements proactively across the squad’s domain; and give design-level code reviews, contribute to refinement, and write clear technical specifications.

What we’re looking for: Strong backend engineering in Java, Spring Boot, JPA/Hibernate, microservices, and REST APIs; production experience with Kafka for event-driven systems; data layer proficiency: PostgreSQL and Redis; familiarity with build and delivery tooling: Maven, Docker, Jenkins; observability mindset: Prometheus and Grafana in production environments; experience with AI-assisted engineering tooling (e.g. Claude) in day-to-day work; ability to own a domain independently – handle most backlog items without direction, drive design decisions and take responsibility for outcomes; writes high-quality, secure, fully tested code with solid monitoring and alerting; clear communicator – able to explain technical risk to both engineers and leadership; and reliable on commitments; unblocks the squad and escalates early when needed. Nice-to-have: fintech or payments engineering background; experience working within regulated financial environments; and mentorship experience with junior engineers.

Why Join us? We’re building the financial infrastructure for MENA. Not as a slogan, as a fact. Since 2019, we’ve become the first regulated Open Banking and Open Finance company operating across the region. Our recent $67.5M Series B from General Catalyst and Sequoia isn’t just validation: it’s fuel. We solve hard problems. We move fast. We hold ourselves to a high standard. Not only do we offer competitive salaries, private healthcare, and flexible office hours, but we also offer a range of benefits that support our people. Lean is proud to be an equal opportunity workplace and an affirmative action employer.
