Senior Software Engineer - (Fullstack/Backend), Team Management

  • San Francisco, CA, USA
  • Employees can work remotely
  • Full-time
  • Alternate Location: Austin, United States

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 make 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 partner with sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, and merchants who began selling with Square and have grown more significant. As our sellers scale, so do our solutions, and 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

As Square has grown, our sellers have gone from businesses with just a few employees to many (sometimes hundreds or thousands!). Team Management provides business owners and managers the tools to manage their entire team. It includes giving permission functionality within Point of Sale and Square Dashboard, plus allowing sellers to track their team's time with time cards. Team Management helps provide our sellers the peace of mind that their business is running smoothly, even if they're not physically present.
