Senior Frontend Engineer
About the role
As a senior frontend engineer in the Lean Lighthouse team, you will be responsible for ensuring that Lean is a sticky experience for our clients, deeply embedded in both their internal and external workflows. Your team builds products which connect end-users’ banking data to businesses such as lenders who can use that data to make better underwriting decisions. You will be responsible for the end-user experience involved in consenting to this journey based on top of our Link SDK, using the latest technologies. Our tech stack primarily comprises React and a strong foundation in underlying technologies like TypeScript is essential.
The Moment
Lean has tripled in size over the past twelve months. We’re on track to triple again next year.
What started as the region’s pioneering Open Finance platform is now becoming something bigger: a multi-product infrastructure company powering payments, data, and lending across MENA. We’re expanding into new markets, opening offices, acquiring businesses, and building capabilities that didn’t exist here before.
We’ve processed billions of dollars in transactions. We’re trusted by 300+ clients - from Binance and Careem to Etisalat - and backed by General Catalyst, Sequoia, and Shorooq. Our $67.5M Series B was just the beginning.

Develop and maintain high-quality frontend applications using React and TypeScript.
Work closely with Design and Product teams to craft excellent UX and UI per User need.
Debug and resolve complex issues, even in unfamiliar areas.
Write clear and concise technical specifications to communicate concepts to stakeholders.
Collaborate effectively with QA to ensure high standards of quality.
Demonstrate an independent, self-starting attitude, requiring minimal supervision.
Go above and beyond when necessary to meet critical business needs.
What we're looking for
Bachelor's or Master's degree in Computer Science, Data Science, Engineering, or a related field.
Proficiency with React and TypeScript in large codebases, and related technologies (Vite, ES6, Radix, ShadCN, Storybook).
8+ years frontend experience as part of a team, following established engineering and project management practices (Agile, Scrum), contributing to code reviews and familiarity with agile ceremonies (planning, refinement, retrospective).
Experience leading frontend system designs and architecture decisions, backed up with written technical specifications/RFCs responding to product requirements.
Experience with advanced React patterns and concepts - Hooks, Context, performance optimization, state management tradeoffs.
Experience with coding standards in a team environment - readability, DRY vs WET, type-safety and testability.
Strong understanding of REST APIs and ability to code high-caliber, responsive UIs with CSS and CSS-in-JS.
Strong experience with CI tools (Git, Jenkins) and testing frameworks (Cypress, Jest, Playwright).
Experience with common frontend features (authentication, authorization, multi-tenancy, A/B testing, search, design libraries, performance, UI experiments)
Skilled in independent problem-solving, debugging and solving complex issues.
Experience with design tools like Figma, and working with design systems with shared React components.
Ability to effectively balance quality and execution speed, with experience reviewing and pairing on code.
Enthusiastic about the JS ecosystem, keeping up with the latest developments, and optimizing web applications for performance, security, and resilience.
Desired Qualifications
Experience in fintech or open banking domains.
Mobile experience is a strong bonus.
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.
