Company Description

Weather Means Business™. WSI is the world's leading provider of weather-driven business solutions that enable enterprises to make better decisions using the most accurate and precise weather data available.

WSI serves some of the world's biggest brands in the aviation, energy, insurance, and media markets, as well as federal and state government agencies. We are proud to be a part of The Weather Company, which focuses entirely on the weather, delivering billions of discrete forecasts per day around the world, through a media portfolio that includes The Weather Channel®, weather.com®, WSI and Weather Underground. Learn more at www.wsi.com.

We have exceptional opportunities for senior developers with demonstrated achievements in developing Java based products. You'll work with and learn some of the newest and most innovative technologies on the planet. Our teams deal with massive real time data sets and finding solutions for solving these “big data” problems using cloud computing (AWS), Cassandra (No-SQL) and a suite of RESTful services and platforms. If you want the opportunity to work with a small team of very talented developers on cutting-edge projects - we want to talk to you.

We're a focused Scrum shop with a strong emphasis on self-managed teams. Our engineering teams value collaboration and hold the team in high regard. We will foster your career development and allow you to be creative in a fun; results based environment. You’ll work on the team that provides the weather data powering many products used by insurance companies across the United States. This data comes from many different sources and formats, and the business needs are constantly evolving. Working on a small, skilled team, you’ll provide the code and architecture to meet the business needs. The products you build will save property, and save lives! 

Successful candidates will have a mastery of server-side concurrent programming on the JVM, and experience in GIS or Weather data sets/systems. In addition you'll be highly familiar with HTTP-based data exchange, large-scale, and high-use apps in both Windows and Unix environments. Our teams will benefit greatly from your proficiency in performance testing and tuning services and applications, SQL, and better yet Cassandra. Functional proficiency with AWS, Spring, Unix, JSON, REST, AJAX, and Maven will put you above the crowd.
