Team

The RX-Tooling team is responsible for delivering integrations, customizations, and services to both our internal operational teams (e.g. Customer Service) and our external customers. The team owns the KYC (Know Your Customer) domain, which is a critical and highly regulated area of our platform. KYC directly impacts customer onboarding, regulatory compliance, fraud prevention, and overall conversion rates, making it both business-critical and operationally sensitive.

RX-Tooling is responsible for integrating with multiple external KYC providers, managing the orchestration logic across them, and ensuring reliability, compliance, and scalability of these integrations. In addition, the team owns the user experience during the early post-registration phase, designing and maintaining the flows that guide customers through identity verification and document submission. Currently the team is composed of a Engineer Lead, Product Owner, 3 Python backend engineers and a mobile/frontend engineer.
