Role

Who you are

Have 2-5 years of iOS experience, working in Swift
Have experience shipping production apps with SwiftUI, and some experience working in UIKit (we use both)
Be interested in learning about and engaging with other parts of our stack (Android: Kotlin/Compose; Frontend: TypeScript/React; Backend: Haskell/Nix)
Be adaptable (we often context switch between product domains), empathetic (product teams are trying to ship product, and don’t always think about mobile first), and pragmatic
Above all else, we’re looking for great engineers with a deep passion for iOS apps and an interest in learning – even if you don’t meet all the qualifications, we’d love to hear from you!

What the job involves

Join a small-but-mighty team of experienced iOS and Android engineers (and one backend dev!) – the team has been making apps for over a decade and we’re pretty darn good at it
Feel a strong sense of product ownership and actively seek responsibility – we often self-organize on small/medium projects, and we want someone who’s excited to lay their own vision atop our foundation and make a big impact across the mobile team and Mercury as a whole
Work closely with designers to ship a beautiful app – they love to collaborate on getting the details right; plus, many of our customers are startups and appreciate our thoughtful, polished designs
Maintain a high quality bar – we provide banking services, so preventing crashes, errors, visual glitches, and wacky edge-cases is a top priority for us

Our take

Frustrated by the archaic, fee-laden banking services offered to entrepreneurs, the founders of Mercury set out to create a better solution. They envisioned a platform that was dynamic, tech-driven, and free from unnecessary fees.

Mercury delivers on this vision by automating business payment processes, offering FDIC-insured accounts, and providing full API access, empowering entrepreneurs with greater control and efficiency. This approach stands in stark contrast to traditional startup banking, which often burdens young businesses with high fees and limited functionality.

By prioritizing user experience and offering a free service tier, Mercury has attracted over 200,000 businesses and achieved a $3.5B valuation as of 2025. As a rising unicorn in the stagnant world of startup banking, mercury is backed by substantial funding and poised for continued growth, constantly adding new features and expanding its team to further disrupt the industry.
