Senior Real-time Java developer

PROJECT OVERVIEW

Our client is a digital media company headquartered in NYC that’s looking to grow the engineering team supporting our Exchange by adding developers. 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. 

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.

REQUIREMENTS

• independence and strong ownership of business problems and their technical solutions;

• excellent problem solving and critical thinking;

• strong Communication and interpersonal skills;

• mastery of algorithms, data structures and performance;

• experience in performance optimization (CPU, Memory, IO) and high-scale (up to 80K req per second per server);

• 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).
