Available Openings

Senior Java Developer

CHICAGO, IL
You're a top-notch Java developer that loves hacking at every level of the stack. It's hard to say what tomorrow will bring, but you'll be happy to hack away at it! Java and multi-threaded programming are your strength, but you'll explore and pick the best language and technology for the task at hand. You can build a back-end system to process huge amounts of data on Monday and tweak automated deployment scripts on Friday. You might not be familiar with every tool we use, but you're a fast learner—you can go from zero to expert in no time flat.
