At Stripe, infrastructure ranges from system design and implementation (such as building out our data tier) to building internal abstractions (such as creating the frameworks used in our codebase) to devops (such as writing tools to manage our server fleet).<p>If you've scaled a distributed system, created developer tools, or designed widely-used libraries, we'd love to talk -- send an email to gdb@stripe.com. Feel free to include a description of your prior work and any other background you think would be relevant.
