Summary
Data Engineer in Boston building scalable, 24×7 Hadoop/Hive data pipelines that process billions of events per day, supporting real-time bidding, reporting, and data distribution. Core stack includes SQL (MySQL/Postgres/Redshift/Hive), Java, Linux/shell, plus Ruby, Go, R, and JavaScript/D3 for reporting and visualization.
By applying and enforcing standard and best practices, you will design and develop scalable, 24×7 data and reporting services to process billions of events per day. Specific duties will include developing enhancements to our Hadoop/Hive based data pipeline and extend to streamed data processing; contributing to data reporting projects including generating internal and external reports or visualizations (CSV, Excel, PDF, interactive web graphics and others) and data distribution / reporting components, real-time bidding or optimization algo using a combination of SQL, Ruby, R, Go, Javascript, D3, Bourne shell scripts, cron jobs, and other relevant technologies. Will also be expected to implement new services and algorithms to improve our product.
The ideal candidate has hands-on data processing experience. Candidate must be familiar with current distributed computing data technologies on commodity servers and have experience with 24×7 production needs.
