Key skills for this role
APEXX is pioneering payment orchestration, transforming the global payments landscape with cutting-edge technology and innovation.
As a leader in Fintech, we're committed to excellence, driving forward-thinking solutions that empower businesses worldwide.
We're looking for a Frontend Engineer to build and evolve the customer-facing surfaces of our payments platform.
Your work will span lightweight, embeddable JavaScript SDKs and payment components used within merchant checkout experiences, as well as sophisticated web applications that enable enterprise customers to understand, configure, and manage their payments.
This is a hands-on engineering role combining deep frontend expertise with exceptional attention to performance, accessibility, and visual craftsmanship.
You'll solve demanding engineering challenges ranging from lightweight, resilient checkout components to rich, data-intensive applications that need to remain fast, intuitive, and responsive while working with complex payment data at scale.
Payments are critical, security-sensitive customer journeys, and the software you build needs to perform reliably and precisely across browsers, devices, and assistive technologies.
Whether you're building an embedded checkout component or a complex dashboard, we expect the same high standard of engineering quality and user experience.
Proven track record as a Frontend Engineer building sophisticated, high-performance web applications, ideally including both complex application interfaces and software embedded into third-party environments.
Deep knowledge of JavaScript/TypeScript, HTML, CSS, the DOM, browser APIs, and the fundamentals of how modern web applications behave and perform - beyond expertise in any individual framework or library.
Strong experience with modern frontend frameworks, preferably React, together with sound understanding of component architecture, application state, data fetching, frontend performance, and modern build and delivery practices.
Experience building performant, data-intensive user interfaces and visualisations, with a strong understanding of how to present and interact with large datasets without compromising responsiveness or usability.
