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. 

All of Block's product services are organized into departments with their own product and engineering teams. Underneath, there's a connected platform team that supports the network. We are that platform. Through data pipelines, we collect data from across Block's ecosystem of products. Our knowledge graph infrastructure contains billions connections between millions entities across Square. This connected data is used across multiple teams, from getting more users onto the Block platform to feature development for statistical models. The scope of this team's work is expanding and there are many opportunities for improving Square's growing global audience.

Within our team, we're looking for engineers to focus on building Block's graph data systems. Our focus is on building fault tolerant systems that make operations, analysts and data scientists happier and more productive.
