Senior iOS Engineer, UI Systems

  • San Francisco, CA, USA
  • Employees can work remotely
  • Full-time

Company Description

Since we first opened our doors in 2009, the world of commerce has evolved immensely – and so has Square. After enabling anyone to take a payment and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn’t work together. So we expanded into software and started building integrated, omnichannel solutions – to help sellers sell online, manage inventory, run a busy kitchen, book appointments, engage loyal buyers, and hire and pay staff. And across it all, we’ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow all in one place.

Today, we’re a partner to sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. As our sellers scale, so do our solutions. We all grow together.

There is a massive opportunity in front of us. We’re building a business that is big, meaningful, and lasting. And we are helping sellers around the world do the same.

Job Description

UI Systems is building Square’s universal design system. This new design system will be deployed across all of Square’s seller facing products on iOS, Android and web, plus promote our public marketing website. This includes our flagship products Point of Sale, Square Register, and Square Terminal. Put simply, this team is building the new public face of Square.

We’re not only building a design system, though: our mandate is wider than that. UI Systems is also building the core UI frameworks and tools needed to make building, testing, and maintaining UI easy and fast at scale: we’re supporting nearly 200 mobile engineers (and growing!) with our work across Android and iOS.

Why are we doing this? As Square grows, ensuring a consistent experience across many products becomes a larger and larger challenge. At Square, we value great and consistent design – UI Systems is here to ensure that Square’s customers and Square engineers alike have a delightful and consistent experience when working with, or working on our products – no matter who built them.

You’ll need to…

  • Be proficient in Swift and/or Objective-C for development (we use both).

  • Enjoy working on mobile apps at all levels – from networking up to user interfaces and whatever’s in between.

  • Build high availability and highly resilient systems which can accept and accurately report payments no matter the network or device conditions.

  • Collaborate with iOS, Android, and Server engineers to ship features.

  • Work closely with product managers and designers to iterate on and define product scope and design.

  • Respond to customer feedback to continuously improve our products.

Qualifications

  • 7+ years of iOS development experience and an excellent command of engineering fundamentals
  • Demonstrated collaboration with co-workers on cross-functional teams and in other locations
  • Desire to understand developer pain points, jobs-to-be-done, and strong sense of ownership
