Our client is looking to grow the engineering team supporting our Exchange by adding developers who are; smart, get things done, communicate well, understand computer science, take pride in engineering, and want to work in an interesting and rapidly evolving industry. 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, our client:

  • 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

Were small enough you can own something and have a direct impact, but big enough that you dont 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 dont water down our responsibilities or expectations).

Some tools we use:

  • GIT, Maven, TeamCity, JIRA, Confluence, Crucible, Intellij, Redis
  • Some practices weve adopted: TDD/unit-testing, continuous integration, code-reviews, Scrum
  • Things were working on: cloud-computing, event-driven IO, self-healing systems, analytic databases
  • We like open source: Spring, Hadoop (we run the NYC Hadoop Meetup), 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 havent had problems buying additions

What youll 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)
  • BS in Computer Science, Mathematics, or Engineering (or professional experience)

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
