Job Description:

Slash is building the future of business banking, one industry at a time. We believe businesses deserve financial infrastructure tailored to how they actually operate. That's why we're creating a new category of business banking. We combine the reliability of traditional banking (high yields, competitive rewards, and comprehensive security) with industry-specific features that make businesses more efficient, more competitive, and more profitable. Slash is, at its core, a technology company and is on a mission to build the best engineering team in the world. We’re looking for an iOS/Mobile Design Engineer to own the front-end experience of our product — from how it looks to how it feels, and how it’s built under the hood.

Job Responsibility:

  • Be the primary directly responsible individual for Slash's iOS app
  • Set the bar for quality, and be responsible for everything iOS related
  • Engineer and maintain our frontend infrastructure for React Native and iOS — everything from design systems to data management to performance
  • Foster and lead a culture of craft — you’ll be setting the standards for our UI and UX across the board
  • Building fast, high-quality interfaces that bring complex financial workflows to life with clarity and precision
  • Crafting smooth interactions, creating well-structured component systems, and collaborating closely with designers to get the details right

Requirements:

  • Has maintained and shipped products to the iOS app store before
  • Has a great sense of design — can think through product flows that make sense while making sure the UI looks and feels amazing
  • Can ship high quality and performant code that scales as the frontend grows and more complexity is added
  • Is thorough and obsesses over the tiniest of details
  • 3+ years experience
  • US citizen/visa only
What we offer:
  • Comprehensive health + benefits plan
  • Unlimited Vacation
  • Opportunity for high growth
  • High autonomy + ownership culture
