Sr. Software Engineer (Fullstack/Frontend), Business Banking

Square - San Francisco, CA

Posted 15 days ago

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

When our sellers make a sale, the Business Banking team helps them manage and understand their business finances with products that include Square Card, Instant Transfers, advanced reporting, and cashflow insights. With this suite of products, we ensure that our customers get access to the funds they need when they need them, and that they can always understand and control where their money is going. We partner with platform and infrastructure teams to move billions of dollars each year on behalf of our sellers.

We are a product-focused engineering team with a full-stack background. Our projects leverage data-driven decisions to deliver features across mobile and web frontends. We also talk directly to existing and prospective merchants about their needs and pain to identify opportunities to improve their experience. Our team enjoys working together to contribute to meaningful work seen by millions of merchants worldwide. As a member of the team, you’ll be working collaboratively with mobile, backend and frontend focused engineers to deliver high-value banking features to Square sellers.

In this role, you’ll help build, maintain, and scale high-performance backend services, build world-class front-end experiences within our web-based products, and contribute to the future of banking.

You will:

  • Help brainstorm solutions and build robust systems to solve customer problems
  • Design, create, and optimize the payment product experience using Java and MySQL
  • Build and maintain new UIs and product workflows in JavaScript
  • Operate and scale a rapidly growing product that is vital to our sellers
  • Design, implement, interpret, and refine A/B tests
  • Build extensive, reliable support for product data logging and metrics
  • Work closely with our product, engineering, analytics, and marketing teams

Qualifications

You have:

  • BS/BA degree or equivalent experience
  • Strong programming skills
  • Great communication skills and enjoy working cross-functionally

Nice to have:

  • Experience contributing to medium to large scale feature releases
  • Experience with Java, JavaScript or Ruby
  • Knowledge of payments or fintech

Technologies we use and teach:

  • Java, Ember.js, MySQL, Ruby on Rails, Go and more
  • A/B test techniques and methodologies
