Job description

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.

What you'll own

• Build and maintain core ledger functionality that underpins Lean's SwiftX compliance use case and regulatory requirements for ADGM scaling
• 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 on a live revenue stream
• Drive stability, performance, and scalability improvements proactively across the squad's domain
• 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 contribute to tech specs
• Writes high‑quality, secure, fully tested code with solid monitoring and alerting
• Clear communicator — able to explain technical risk to both engineers and leadership
• 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
• Mentorship experience with junior engineers

NB. While we think the above experience could be important, we’re keen to hear from people that believe they have valuable experience to bring to the role. If you identify with the team and mission, but not all of our requirements, then please still apply!!

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 UAE and Saudi Arabia. We’ve processed billions of dollars. We connect millions of accounts. We enable companies like Binance, Careem, and Etisalat to build products that were previously impossible in this region.

Our recent $67.5M Series B from General Catalyst and Sequoia isn’t just validation: it’s fuel. We’re expanding into new markets, launching new products, and setting the pace for what financial innovation looks like in MENA.

We solve hard problems. We move fast. We hold ourselves to a high standard. And we’re looking for people who’ve done this before to help us do it right.

If you’re motivated by building something that lasts, not just something that scales, Lean is where you need to be.

Not only do we offer competitive salaries, private healthcare, and flexible office hours, but we also insist that every member of the team hold a meaningful equity stake in the business to ensure long‑term alignment. We'd love you to join us for this journey!

Lean is proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.
