  • • You will be instrumental in developing and enhancing a unified client-side SDK. This sophisticated tool is designed to abstract complex processes such as identity verification, device intelligence, and document capture, presenting them through a single, elegantly designed integration.
  • • Your work will directly empower financial institutions to onboard their customers securely, seamlessly, and efficiently, contributing to a critical aspect of their operational success.
  • • This is a high-impact position offering unparalleled opportunities for rapid skill development and the chance to ship meaningful, tangible work from your very first day.
  • • We are seeking individuals with a strong command of modern JavaScript/TypeScript, proven experience in building sophisticated front-end applications, and a keen interest in developing SDKs or developer-facing products that operate within the browsers of our clients.
  • • A core responsibility will be to build and extend the core functionality of our client-side JavaScript/TypeScript SDK. This involves orchestrating the seamless interaction of multiple third-party vendor scripts, abstracting their complexities behind a unified, headless API.
  • • You will play a key role in developing and continuously improving the hosted verification experience. This involves building and refining a secure, embeddable web application that renders interactive identity verification flows with a highly polished, brandable user experience.
