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 are looking for a quantitative, AI-fluent early-career professional to fill a data science role focused on payments data across Square and Cash App. You will partner closely with Product, Operations, Finance, and Engineering, leveraging data tools to optimize our payments platform from success rate, to cost efficiency, to risk mitigation. In addition to vertical work focused on the Payments domain, we also expect you to contribute to horizontal initiatives across the broader Data Org from data systems, to process and tooling.

Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block. The Role The People Technology team, part of the People Automation and Operations organization, manages the infrastructure powering Block's employee lifecycle from recruiting to off boarding.

Automate recurring operational work, sustainably. A meaningful share of the work supporting our People stack repeats. You'll replace it with automation built to last — documented, maintainable, and designed as shared capability rather than one-off fixes. Make other builders faster. As teams across People build their own AI-enabled solutions, you'll give them the underpinnings: trusted data access, integration patterns, reusable tools and agents, and clear guidance on what's safe to build and what isn't. You Will Talent Acquisition Partnership & Platform Strategy Partner with Talent Acquisition and other People teams to understand business challenges and identify opportunities to improve work through technology and AI. Advise teams as they evaluate and design AI-enabled solutions that are scalable, secure, and grounded in trusted People data.

Platform Architecture & Integration Design Build and enable shared integrations, data services, and platform automations that accelerate AI-powered solutions across the People organization. Evaluate and manage People Technology vendors, weighing build, buy, and integration decisions. Evolve People Technology toward consistent, shared platform capabilities and architectural patterns that empower builders across the organization. AI, Automation & Innovation Use AI and modern development tools to prototype, automate, and deliver technology solutions that improve the employee and candidate experience. Partner with builders across the People organization so solutions draw on trusted data, follow governance standards, and are designed for maintainability and scale. Evaluate emerging technologies and identify opportunities to improve productivity, employee experiences, and operational effectiveness. Platform Operations & Governance Steward our core People Platform, including systems of record such as Workday and Greenhouse, ensuring reliable, secure, and scalable operations. You Have Minimum of 5 years of related experience with a Bachelor's degree; or 3 years and a Master's degree; or a PhD without experience; or equivalent work experience. Experience managing enterprise People platforms such as Workday, Greenhouse, or similar systems, including hands-on work designing or implementing integrations between them using APIs, middleware, ETL tools, or integration platforms.

Experimented with AI tools to automate work or build solutions, and can talk through what you tried, what you learned, and how you'd apply it to People Technology challenges. We're all learning, but you need to have started.
