We have an experienced team that is looking to add developers seeking technical challenge and empowerment to make decisions that really move the business forward.

**Some major projects the Exchange team is currently working on:** continuing to scale our core exchange platform, honing the intelligence of our optimization, cutting feedback time for business intelligence, and aggressive automation. 
Currently, we:
● handles millions of transactions per second, hundreds of billions of times each day
● evaluates, selects, and optimizes ad-serving based on advanced statistics and machine-learning
● returns responses collected from dozens of parties in milliseconds
● constantly evolves to meet market demands that change in days and weeks, not months/years
● factors thousands of data-points in every serving decision

We’re small enough you can own something and have a direct impact, but big enough that you don’t have to do it alone. We care deeply about quality and doing the right thing, but have a strong focus on business value and time to market – and believe that focusing on the first part enables the second. Developers have technical management (who are technical and write code), as well as direct access to business, product, and operations (and they have access to us). Lastly, our Sr. Engineers have lots of empowerment and freedom of action (but we don’t water down our responsibilities or expectations)

**Some tools we use:
**● GIT, Maven, TeamCity, JIRA, Confluence, Crucible, Intellij, Redis
● Some practices we’ve adopted: TDD/unit-testing, continuous integration, code-reviews, Scrum
● Things we’re working on: cloud-computing, event-driven IO, self-healing systems, analytic databases
● We like open source: Spring,** Hadoop**, Jetty, Linux, Memcache
● Developers get fast boxes, with multiple monitors, and can choose Windows or Linux
● We keep a library of technical books (several hundred) and haven’t had problems buying additions

**What we value as a team:
**● Code built for Performance and Scale
● Solid engineering practices (e.g. design patterns, automated testing, fault-tolerant systems, KISS)
● Leveraging Open Source
● Agile development and tight interaction with business/operations
● Automated testing
● Developers who can navigate around a Linux box
● Passion, technical expertise, and personal accomplishment
● Rolling up your sleeves and getting things done
