Job 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, 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

Restaurants today operate in an increasingly dynamic landscape, and we're building a modern product ecosystem to support this. The Food & Beverage (F&B) team at Square empowers restaurant businesses of all kinds to start, run, and grow their businesses through advanced workflows, specialized products, business insights, and inclusion in the greater Square ecosystem. In everything we build, we focus on efficiency, automation, and reliability: themes of paramount importance in a fast-paced environment where great hospitality is key.

Within a Restaurant, the Back of House is where all of the food is prepped, cooked and plated ensuring customers get timely service and enjoy their meal. The Back of House team encompasses the Kitchen Display System (KDS) and printed paper tickets, which are crucial parts of restaurant operations, ensuring orders reach the kitchen and are prepared correctly.

As a Staff Android engineer on the Food & Beverage team, you'll work closely with other engineers and cross-functional partners to ensure our applications are maintainable, and capable of meeting the diverse needs of our merchants. You'll play a pivotal role in enhancing the performance and reliability of our Android solutions, directly impacting millions of users worldwide. This position requires both deep technical expertise and the ability to collaborate and drive strategic initiatives.

You Will

    • Architect and improve the KDS codebase to support diverse merchant workflows within a single product
    • Collaborate with product managers, designers, and engineers across teams to deliver high-quality, scalable features
    • Champion best practices in Android development, ensuring code quality, performance, and maintainability
    • Identify, debug, and solve deep, complex technical problems that cross organizational boundaries
    • Provide technical mentorship and guidance to engineers, fostering a culture of learning and innovation
    • Identify and drive improvements in our Android development processes and tools, contributing to the technical roadmap
    • Proactively identify and advocate for strategic technical initiatives, building alignment with peers and leadership
    • Participate in and lead incident response, including on-call rotations and post-mortem processes
    • Move between the Solver and Architect archetypes, spending the majority of your time actively in or around code (be that Kotlin, Java, SQL, LookML, etc.)

You Have

    • 12+ years of Android development experience. We make heavy use of Kotlin, Workflow, and Jetpack Compose
    • Proven experience in architecting and leading complex Android projects at scale
    • Strong collaboration skills, with experience working across team and organizational boundaries to deliver cohesive, user-focused solutions
    • A track record of being self-directed, innovative, and biased towards action in a fast-paced environment
    • Proven ability to influence technical direction across organizational boundaries
  • Excellence in technical communication and relationship bu
