Must have RTB/programmatic experience

Some major projects the Exchange team is currently working on: continuing to scale the core exchange platform, honing the intelligence of our optimization, cutting feedback time for business intelligence, and aggressive automation. Currently, they handle:

• Handles hundreds of thousands of transactions per second, billions of times each month
• 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

They are small enough that you can own something and have a direct impact, but big enough that you don’t have to do it alone. They 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 the company).

Some tools they use:

• GIT, Maven, TeamCity, JIRA, Confluence, Crucible, Intellij, Redis
• Some practices they’ve adopted: TDD/unit-testing, continuous integration, code-reviews, Scrum
• Things they’re working on: cloud-computing, event-driven IO, self-healing systems, analytic databases
• They like open source: Spring, Hadoop (they run the NYC Hadoop Meetup), Jetty, Linux, Memcache
• Developers get fast boxes, with multiple monitors, and can choose Windows or Linux
• They keep a library of technical books (several hundred) and haven’t had problems buying additions

What you’ll need:

• Independence and strong ownership of business problems and their technical solutions
• Excellent problem-solving and critical thinking
• Strong Communication and inter-personal skills
• Mastery of algorithms, data structures and performance
• Experience in performance optimization (CPU, Memory, IO) and high-scale (>500 req/sec)
• Experience with open-source projects and tools (e.g. apache projects, maven, Spring, tomcat/glassfish)
• Experience with Agile, tight interaction with business and operations (DevOps)
• Experience with automated testing (TDD, Mocking, Unit/Functional/Integration)
• Expert Knowledge of Internet technologies/and protocols
• Expert knowledge of the Java language, platform, ecosystem, and underlying concepts and constructs
• Knowledge of common design patterns (IoC, GoF – not J2EE Pattern Library)
• B.S. in Computer Science, Mathematics, or Engineering (or professional experience)
• Basic knowledge of Python a plus, but not critical

What they 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
