MAJORITY is a groundbreaking all-in-one digital financial service app that includes an FDIC-insured account, Visa® Prepaid card, money remittance, and international calling. We are built for migrants, by migrants.

Global migration is a 21st-century reality. Whether people are following their dreams, love or new experiences, more and more of us are leaning towards new environments. Our purpose at MAJORITY is to empower the amazing, the brave, and the talented and help them achieve all of their ambitions.

We believe that everyone deserves the same opportunity to succeed. Our mission is to provide migrants the tools to thrive in their new country.

We are a diverse group of people from over 40 different countries that come together every day and we’re looking for others driven by the same desire to create meaningful products that bridge cultural and geographic distances.

MAJORITY is looking for a skilled iOS Developer to join its Mobile team. This is a full time, in-person position based in Stockholm, Sweden. Developers may work from home up to 2 days a week.

About our mobile apps and MAJORITY

Our work matters to real people. It is the app they open to get paid, check their balance or send money home.

We build banking in an app: identity checks with document and selfie capture, card management and Apple Pay provisioning, international money transfers, a credit card, calling and phone plans.

Our app is written entirely in Swift, split into modular Swift packages with our own design system. The use of SwiftUI is growing and Swift concurrency is used throughout.

We release every two weeks, backed by snapshot tests, unit tests in Swift Testing and an XCUITest suite.

AI is part of how we build. Our repo ships skills for implementation, multi-agent code review, verifying features, writing UI tests etc. We keep improving them together.

To secure high quality code we practice code review and pair programming, we use CI/CD and automated testing.

Our engineers own what they build. We take on new challenges, not just new features, from new products to partner SDK integration.

We also have a lot of fun together. We have a lunch run club, play foosball and other games, go to the gym, AWs etc.
