Android Engineer, Payment Acceptance

Full-time

Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

Come join one of the many teams within Seller at Square – we build the products that our millions of sellers use every day to run and grow their businesses. Each team included below has unique and interesting opportunities – there’s almost certainly something for you!

Within Square’s Seller team, we value (and practice) deep collaboration between teams and disciplines. You’ll be working with engineers across the organization to design and implement solutions to problems with direct impact on our customers. You’ll be working regularly with product managers and designers to make sure we’re shipping the right things to our sellers and iterating based on their feedback.

Payments Acceptance Mobile
- Payment Acceptance Mobile builds SDKs for developers that build applications which take payments via Square – either talking to Square hardware via our Reader SDK, storing a card in buyer facing applications via our In-App Payments SDK, or using Square Point of Sale via our app-switch API. We work closely with both the Checkout Flow team, the Connected Device Experience team, and the Mobile Security team to create, package, and document the code that Square uses in our applications into ergonomic and simple SDKs that handle the complexities of taking card payments.
- As part of the Payment Acceptance Mobile team, you'll be building SDKs that not only serve Square's products, but also independent and professionally developed applications that Square wouldn't build. You'll bring the same product quality focus from Square products to building developer tools and libraries that allow our customers to never miss a sale.

Qualifications

You’ll need to…

Be proficient in Java and/or Kotlin 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 report payments no matter the network or device conditions.
Collaborate with iOS, Android, and Server engineers to ship features.
Work with product managers and designers to refine and define product scope and design.
Respond to customer feedback to improve our products.
