Sr. Operations Research Analyst

  • 855 Main Street, Suite 400, Bridgeport, CT, United States
  • Full-time

Company Description

The world has changed. More store closings were announced in 2018 than any other year on record. JC Penney, Sears and Toys ‘R’ Us, once household names, are either bankrupt or facing existential crisis. Amazon has disrupted retail. Online customers now expect FREE and FAST shipping as a result of the Amazon Prime Effect. According to the Wall Street Journal “Alongside life, liberty and the pursuit of happiness, you can now add another inalienable right: two-day shipping on practically everything.” But the reality for retailers is, shipping is NOT free. It is the second biggest drain on their profits after inventory leading to record-low margins. The Cahoot team is on a mission to help online retailers improve their profit margin and competitiveness by re-writing the rules of conventional supply chain and fulfillment. This means faster delivery to customers, a more efficient supply chain network, lower cost of operations for merchants and less carbon emission for a greener planet. Our solution uses Co-opetition as the underlying business strategy to solve a problem that even the largest retailers like Walmart, Target and eBay are struggling with.

Job Description

Cahoot is seeking a Senior Operations Research Analyst with strong numerical optimization and analysis skills and practical modeling experience to disrupt traditional logistics and drive the future of our new patented (10 US Patents Awarded) application. The qualified candidate will have proven experience implementing numerical optimization methods designed for complex combinatorial optimization and vehicle routing.

You'll design, test and develop the algorithms and software architecture of our next generation order fulfillment optimization and routing engine.
