It all started with an idea at Block in 2013. Initially built to take the pain out of peer-to-peer payments, Cash App has gone from a simple product with a single purpose to a dynamic ecosystem, developing unique financial products, including Afterpay/Clearpay, to provide a better way to send, spend, invest, borrow and save to our 50+ million monthly active customers. We want to redefine the world's relationship with money to make it more relatable, instantly available, and universally accessible. Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward innovation, collaboration and impact. We've been a distributed team since day one, and many of our roles can be done remotely from the countries where Cash App operates. No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy. The Role We're the Access team, and we're building the next generation of authentication and permissions infrastructure for Block. Behind every login and every account there's a platform that needs to be both rock-solid and remarkably flexible. This isn't about maintaining legacy systems, it's about building the foundation that will enable Cash App and Block's ecosystem to scale while serving increasingly diverse customer needs. The Challenge: As Block accelerates product innovation, we're seeing an explosion of new use cases: different account capabilities, different authentication requirements, different customer cohorts with different needs. We're building a platform that lets product teams move fast while we maintain the trust and security that our customers depend on. The Opportunity: You'll be joining at an inflection point. The decisions we make now about architecture, about APIs, about how we enable other teams-will define how Block scales for years to come. This is foundational work with massive leverage. You Will Design and build the APIs and services that power Authentication & Permissions across Cash App and Block's ecosystem, the systems that determine who can access what, and how they prove they are who they say they are. The work is varied and impactful. You might: Build fine-grained permissions systems that enable different roles and capabilities across various account configurations Build secure authentication experiences that protect customers while maintaining seamless access to their accounts Improve account recovery success rates, helping legitimate customers regain access while keeping bad actors out Consolidate authentication platforms, migrating critical flows into scalable, composable services Design authorization primitives that product teams across Block can use to build secure, flexible experiences How you'll work: You'll navigate complexity with pragmatism. You'll balance immediate business needs with long-term platform goals. You'll ship iteratively while keeping the big picture in mind. You'll collaborate across product, design, security, and engineering teams. You'll think critically about priorities. You'll adapt and thrive in an environment where priorities shift and requirements evolve.The common thread: you'll be solving complex technical problems that directly impact both customer trust and product velocity. You'll need to balance pragmatism with technical excellence-shipping iteratively while building toward a coherent platform vision. You Have 5+ years building and operating production systems with demonstrated impact and technical ownership Ability to think critically and analyze complex problems, weigh trade-offs, and make pragmatic decisions that balance competing priorities A bias toward iterative delivery. You know how to break big problems into shippable pieces and maintain momentum through ambiguity Comfort with complexity. Whether it's large codebases, distributed systems, or evolving requirements, you don't get overwhelmed; you get strategic Excellent communication skills. You can explain technical concepts clearly, build alignment across teams, and adapt your style to different audiences Customer empathy. You understand that behind every API call is a person trying to access their money, and that matters High technical standards in software testing, delivery, and operational excellence Adaptability and resilience. You stay calm and focused when priorities shift or requirements change Even Better If You Have Experience with authentication, authorization, or identity systems Experience working in large codebases and breaking apart monoliths Background in security, fraud prevention, or trust & safety domains Experience building platform or infrastructure that other engineering teams depend on Track record working effectively in distributed or remote teams Technologies We Use and Teach Java, Kotlin, Golang HTTP, JSON, gRPC, Protocol Buffers MySQL, Hibernate, DynamoDB Kafka and event-driven architecture DataDog, Prometheus AWS, Kubernetes We're working to build a more inclusive economy where our customers have equal access to opportunity, and we strive to live by these same values in building our workplace.

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 We believe everyone should be able to participate and thrive in the economy. So we're building tools that make commerce easier and more accessible to all. We started with a little white credit card reader but haven't stopped there. Our new reader helps our sellers accept chip cards and NFC payments, and our Cash app lets people pay each other back instantly. We're empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. Let's shorten the distance between having an idea and making a living from it. We're here to help sellers of all sizes start, run, and grow their business-and helping them grow their business is good business for everyone. Connected Devices (CD) CD owns the platform for connected devices here at Square. We're one of the many essential teams that merchants depend on to help them run a remarkable business. They work on integrating our hardware products with our mobile apps: think Readers, Terminals, Registers, and Handheld. As a member of CD, you'll be working at the intersection of hardware, product, and platform solving hard technical problems. Your contributions will span from internal teams to our merchants and everything between -- creating memorable and seamless experiences for Square's ecosystem. You Will Build and improve the mobile experiences that power Square's connected hardware products using Java and Kotlin Work across the full mobile stack, from networking to UI, to create smooth and reliable hardware integrations Develop systems that stay reliable and resilient so sellers can accept and report payments in any network or device conditions Partner closely with cross functional engineers to ship high quality features Work with product managers and designers to shape product scope and deliver clear, intuitive user experiences Use customer feedback to guide improvements and strengthen overall product quality Work directly on mobile and hardware integrations including BLE, USB, and similar technologies You Have At least 8 years of relevant industry experience Strong experience building production mobile apps in Java and Kotlin A background in building reliable systems that perform consistently in a variety of environments A history of working closely with hardware, software, and product teams Hands on experience connecting mobile apps to hardware through BLE, USB, or related methods A customer first mindset and a comfort level solving complex problems across different parts of the ecosystem We're working to build a more inclusive economy where our customers have equal access to opportunity, and we strive to live by these same values in building our workplace.
