Senior Staff Software Engineer, Square Invoices (Remote)

Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments 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, offer buy now, pay later functionality, book appointments, engage loyal buyers, and hire and pay staff. 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 in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale.

Today, we are a partner to sellers of all sizes – large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We’re building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same. .

The Role

The Square Services team is dedicated to empowering Home & Repair and Professional Services sellers with tools that allow them to manage their businesses on the go. We own and develop Square Invoices, which enables merchants to send invoices and receive payments remotely. Our team also builds a suite of solutions, including Square Contracts for agreement management, Square Virtual Terminal for accepting payments directly from a desktop, and project workflow tools for seamless operations. In this role, you’ll contribute to shaping the team’s roadmap and strategy, playing a key part in driving our server team’s success toward ambitious growth goals.

Square Invoices is the easiest way for merchants to close sales and collect payments remotely. Our customers rely on our products because they are well-designed, easy to use, and integrated with their business. We are a full-stack product oriented team, spanning across engineering, design, product, data science, and marketing. You’ll implement management’s strategy decisions and will play a critical role in helping the team accomplish our industry-leading growth goals.

We are focused, and rapidly growing with an abundance of growth and impact opportunities. We focus on building the best tools to help our merchants close sales and get paid quickly, anywhere, at any time. At the same time, we are doing this in a thoughtful and scalable way, making smart choices about how to automate critical functions for our merchants.
