But, not all Big Data is created equal! At Dachis Group, our data analytics platform delivers meaningful social insights for the world's largest companies and most valuable brands. Specifically, we analyze the relationships, behaviors, and conversations between 30,000 brands and 100M social accounts every 15 minutes. So yeah, our data is big, but it's also complex--filled with business intelligence just waiting to be discovered.

As a core member of the Big Data team @ Dachis Group, you will be challenged daily with fun, mind-bending problems in distributed graph processing, text mining, machine learning, statistical analysis, and data management. You'll also get to work side-by-side and learn from experts in these areas; many of our team members are published authors in fields related to NoSQL, search, and large-scale machine learning. Moreover, we work with hot Big Data technologies, such as Hadoop, Pig, Cassandra, Oozie, and cloud services. Our lean-startup driven team practices Kanban and dev-ops is central to our engineering process. Your great ideas and hard work are delivered to our customers in hours to days, not weeks to months.

Requirements & Skills:

  • NoSQL, preferably distributed peer stores like HBase and Cassandra
  • Text mining and/or NLP and/or Machine Learning (any framework, any language)

We assume you have a solid foundation in computer science, data structures / algorithms, and development in a -nix environment. Most importantly, you need to bring your passion about data and all the wonderful possibilities available in analyzing social data at scale.

Overall Responsibilities:
  • Members of the Big Data team at Dachis Group must be versatile and willing to master new technologies and processes. Here are some of the primary tasks each member of the team is expected to contribute to:
  • Developing Pig scripts and custom MapReduce jobs to measure business outcomes from social media
  • Designing complex data processing workflows involving Cassandra, Pig, Oozie, Mahout, and Hadoop
  • Performing experiments and analyzing results to improve the performance and quality of our algorithms
  • Working closely with product management team to develop summary reports and data visualizations using R, Excel, and SQL
  • Constantly learning and experimenting with APIs and data provided by social networking sites like Twitter, Facebook, and YouTube
