We have been recognized as one of the Best Places to Work by Glassdoor and ranked No. 241 on the Inc. 500 List, the most prestigious ranking of the nation’s fastest-growing private companies.

Bluecore’s Integrations Engineering (IE) unit is a software engineering team dedicated to helping Bluecore customers extract maximum value from the Bluecore Retail Data Platform.  As an IE, you will bring your technical know-how to the main connections of the Bluecore engine to our clients - drawing meaningful intelligence from their websites and implementing marketing solutions that map to the customer’s vertical, audience behavior, and product mix.

As an Integrations Engineer, your principal responsibilities will lie in (1) maintaining and writing JavaScript-based integrations that live on client websites, (2) configuring, monitoring, and maintaining the intake and manipulation of client data, and (3) utilizing internal infrastructure, tooling and documentation to solve complex, often-unique, client-specific problems.

You enjoy the puzzle and the process of iterating and ideating before implementing a solution, and you are able to break complex problems into simple components for better analysis and digestion.

-Metrics and Data: You are someone who finds yourself consumed by daily, weekly and monthly metrics and loves turning those into best practices. Seriously, your work will be driving executive-level decision-makers at industry-leading brands on best business practices.

-Curiosity and Growth: You are someone who actually believes that diversity in thought and skills makes for a better workplace and a better you.
