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...

We are currently recruiting for a Full Stack Developer with good hands on experience of AWS and JavaScript. Why do we need Full Stack Developers? Our applications are made up of frontends, backends and infrastructure. We believe that if we have engineers capable of working on all three, the result is a much more cohesive application that is easier to evolve and maintain over time. We therefore encourage all of our developers to get involved in all aspects even if they've only ever worked on one of them in the past. We don't want to put people into boxes and limit their ambition or creativity, our goal for our engineers is to help them reach their potential. We can do this by providing the freedom to try new things, learn new skills (from formal training and collaboration) and get things wrong a few times before getting them right (without upsetting our customers!). We have a sack full of ambition and a backlog full of ideas to provide the best experience to our customers. We...
