Role

Who you are

Be interested in continually honing their craft
Have curiosity and be willing to share their perspective
Appreciate quality in their work and that of others
Communicate well, and be able to write clear explanations of their reasoning on technical decisions

What the job involves

This is a paid full-time remote summer internship for 12-16 weeks between May - September
Our internship program is intended for individuals enrolled in an academic program (undergraduate, graduate, etc.)
We think Davy’s sacrifice was worth it, though, since Faraday went on to do experimental work in the field of electromagnetism that is foundational to innumerable modern technologies
While we can’t promise you’ll become the next Faraday, we can promise you won’t be asked to deal with explosives on the job
Instead, you’ll be receiving mentorship from experienced mobile engineers (iOS and Android), writing Swift/Kotlin (maybe some TypeScript code), and contributing to a product that serves over 100,000 businesses
You’ll be joining as a Mobile Engineering Intern; we’d like to see folks who’ve got existing experience with native iOS or Android apps (no React Native, sorry!
) and might have some interest in working on some mobile-related full-stack tooling
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
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
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
Have a possible interest in other parts of our stack (Android: Kotlin/Compose; iOS: UIKit/SwiftUI/RxSwift; Frontend: TypeScript/React; Backend: Haskell)
Have existing experience in either/both iOS or Android, using UIKit/SwiftUI (iOS) or Jetpack Compose (Android)

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.
