Design Engineer, Open Source Design

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

As part of a newly formed Block central design team, our mission is to reinvent the way we design, build, and govern product ecosystems, internally and externally to Block, while showing the world what open source design looks like in the process.

• A track record of defining major workstreams, setting clear success measures, and driving execution.

Even Better
