System Admin / Security Specialist

Three Points recently partnered with an exciting tech company that provides cross-device technology to improve digital advertising and user analytics, who are looking to add an experienced System Admin & Security Specialist to their team.

The team uses deterministic and probabilistic methods, including proprietary algorithms and machine learning technology, to identify users across channels and devices (such as tablets, laptops, desktops, smartphones, smartwatches, or other wearables) with a high degree of accuracy.
