ExPretio | Montreal, Canada | DB Dev, UI/UX JS Dev, Lead QA, Deployment & Support Manager | ONSITE We provide software to help passenger transport companies do revenue/yield management. Know how plane tickets change prices? We make it happen for train companies so that they best use the seats they have on each departure. This means lots of data, non-trivial problems, interesting algorithms, some machine learning and a lot of fun. http://www.expretio.com/about/#careers
