Staff Engineer

About the role
As a Staff Engineer on the Credit Scoring & Underwriting squad, you'll lead the technical architecture and execution across credit insights products. That means the insights and data platform our lenders already build on, and the new products we're putting on top of it. It's a hands-on job. You'll write production code, and you'll be the person the team pulls in when a problem is hard or badly defined. You'll also put real time into helping the engineers around you get better, through code reviews and mentoring.

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
