Company Description

About Starschema 
At Starschema we believe that data has the power to change the world and data-driven organizations are leading the way. We help organizations use data to make better business decisions, build smarter products, and deliver more value for their customers, employees and investors. We dig into our customers’ toughest business problems, design solutions and build the technology needed to address today’s unique challenges.  
What you can expect as a Starschema team member 

As a member of the Starschema team, you will be on the front lines of digital transformation, working with some of the most innovative Fortune 500 companies to drive innovation and realize the promise of data-driven cultures. You will learn and use the latest data-centric technologies along with the core industry technologies.  


Our team is inclusive and fun. While we take our work seriously, we know how to have a good time while doing so. We encourage everyone to share their opinions and ideas, and our leadership wants to hear everyone’s input no matter what role they play in the organization. 
Your future at Starschema 
You may have heard that Starschema has been acquired by HCL Technologies. While we have new ownership, our immediate leadership will not change, and we will function as a self-directed operating unit. This ownership change will enable Starschema to grow at an unprecedented rate and this means many career advancement opportunities for all our team members. We will not only have more operating resources to draw upon, but also have a broad array of excellent training programs — from highly technical to everyday soft skills to leadership and everything in between.  We’ve always have had a culture of “never stop learning” and we’re now taking that to the next level.
