About The Employer:


Senior Data Engineer, an award-winning leader in contact centre AI software, helps financial services companies be compliant and improve customer service by monitoring 100% of their customer interactions. CLIENT uses artificial intelligence to transcribe and automatically analyse and review interactions to identify and handle problematic interactions (customer complaints and interactions with vulnerable customers) according to regulatory requirements. The AI solution “listens” for potential problems and compliance breaches and alerts users (supervisors and quality assurance teams) of calls that need further review and remediation.
Financial services companies have a huge compliance problem, particularly in the context of contact centre quality assurance. These companies struggle to monitor 100% of customer interactions due to the high cost of employing more and more quality assurance assessors. As a result, the average company monitors only 4-5% of customer interactions. This results in a large number of unchecked interactions, including complaints, compliance breaches and poor agent behaviour.
That’s where CLIENT comes in! CLIENT has built strong compliance models and cutting-edge software to revolutionise the contact centre quality assurance process. In 2021, CLIENT was selected as the winner of the Accenture Blue Tulip Awards and the KPMG Digital Innovation Challenge. All of this has been achieved by our team of highly-motivated, diverse and purpose-driven individuals.
