Square
Senior Software Engineer, Android Payment SDKs
Square, San Francisco, California, United States, 94199
Company Description
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 through Afterpay, 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.
Job Description
Our Payment SDK teams serve both third-party developers who create their own applications using Square’s ecosystem, and also our own developers creating Square’s own applications. Our external customers include some of Square’s largest, and internally we collaborate with unusually many other teams, from device firmware to server APIs and services, from low-level security and account identity to developer support and sales engineering. In some ways our focus is narrow—we move money for in-person transactions, and do only the bare minimum of other functions required for that—but is, in a very real sense, the heart of Square.
You Will:
Design and implement features to expand the Android SDK products’ addressable market to new developers, merchants, and buyersHelp balance the external-facing and internal-facing demands, including designing APIs and systems that meet the sometimes-competing needs of bothCollaborate with some truly excellent teammates, both in the SDK team and adjacent to it, and help to onboard new engineers and develop the existing ones to remain excellent and to further improve both your peers and yourselfQualifications
You Have:
At least eight years’ experience as a software engineer, including at least several years’ experience working in Kotlin on Android in a professional environment. To us, “professional” means working in a group on something larger than your own efforts, using normal tooling such as IDE development, revision control, unit and UI testing including continuous integration systems, and gathering analytics data and troubleshooting of field issuesExperience not only implementing significant projects, but in resolving ambiguous and competing goals, identifying requirements, and designing and decomposing a tractable solution to those needsExperience in refactoring a complex code base, maintaining it and adapting to both changing circumstances and to correct past errors and misjudgementsExperience mentoring both junior and peer teammates, as well as receiving and learning from both peer and senior colleagues and managementIt’s a plus if you have developed Android SDKs as opposed to only applicationsIt’s similarly a plus if you’ve previously worked with payments, in finance, or in some other highly-regulated field or context. If not, no worries, you’ll learn. A lotIt’s a plus if you’ve had end-to-end ownership of something, and particularly ownership of build and release stages as well as feature layersIt’s a plus if your prior work included client/server communications and dependency injection. Again, we can teach you, but it’s a nice-to-haveTechnologies We Use and Teach:
KotlinAndroid APIsPatterns and models both for Android apps, in which we have control of the whole thing, and for SDKs, in which our developer customers can do unexpected and uncontrolled thingsCommon Android tools and libraries, such as Dagger dependency injection, OkHttp and Retrofit communications, Google protocol buffers. Also some uncommon ones Square releases, such as WorkflowsFinance and Payment regulations, both in the US and in countries where Square operates. These include PCI, SPoC, and MPoC standards and requirements, for exampleTesting frameworks and methodologies at a variety of levels, from simple unit tests to UI tests and nearly full-stack integration tests to humble manual testingAdditional Information
