Software Engineering Intern

As a Software Engineering Intern at Lean, you'll ship real enhancements to the infrastructure our clients use to move money and access financial data. Production code, reviewed by experienced engineers, used by clients.

You'll work across several of our Java Spring Boot services, running on Kubernetes. AI-assisted development is central to how we work:
Claude Code is part of our standard toolchain, we provide a generous (near-unlimited) usage quota, and we expect engineers at every level to be fluent with it, using it to move faster while staying firmly in control of what ships.

You'll have a dedicated mentor, along with your team and manager, to set and track development goals with you. The internship is designed as a path into a full-time engineering role at 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 Tabby and Tas’heel to Hungerstation - 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.

• Design, develop, test, and debug software enhancements from ticket to production, with your mentor reviewing your work
• Use agentic coding tools (Claude Code) to raise both the quality and velocity of your work, and help the team build good patterns for using them well
• Take part in code reviews on both sides: act on feedback on your code and give considered feedback on others'
• Learn the team's tools, languages, and workflows fast enough to ship something in your first few weeks
• Join stand-ups, planning, and reviews, and flag early when something you own is at risk of slipping
• Build a working understanding of our clients, their end-users, and the regulated environment we operate in
• Get involved beyond your team: company events, demos, and cross-team work

• Final-year student or graduate within the last 12 months in Computer Science, Software Engineering, or a related field
• Hands-on experience using agentic coding tools as a core part of your workflow (we run on Claude Code), with the judgment to know when to trust their output and when to scrutinise it more closely
• Working proficiency in at least one language such as Java, C++, Python, or similar
• A grasp of the fundamentals: version control, testing, and debugging
• Something you've built outside coursework: a side project, hackathon entry, open-source contribution, or previous internship
• Problem-solving you can articulate. You can walk us through how you broke a hard problem down
• Clear written communication. You can explain what you built and why you built it that way
• Independence, plus the judgment to ask for help rather than stay stuck
