About the role

HEADLINE: Job Title: Software Engineer, Frontend Reporting to: Engineering Manager Location: Remote initially, with plans to transition to hybrid working as we expand in the region.

ABOUT THE 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.

WHAT YOU'LL DO:

- Design, build, and maintain robust, lightweight, high-performance JavaScript/TypeScript SDKs and payment components that integrate seamlessly into diverse merchant environments, with rigorous attention to isolation, backwards compatibility, browser behaviour, security, accessibility, and performance.

- Build and evolve sophisticated merchant- and internal-facing web applications, creating polished, responsive, and highly performant experiences across complex workflows, large datasets, dashboards, and data visualisations.

- Raise the bar for frontend engineering and visual craftsmanship, translating product and design intent into precise, accessible, and intuitive experiences that perform consistently across browsers, devices, and merchant environments.

- Work confidently across the frontend/backend boundary, understanding underlying services, APIs, and data flows and, where appropriate, designing and building Backend-for-Frontend services to create performant and maintainable frontend experiences.

- Engineer for quality throughout the delivery lifecycle, using appropriate automated testing, performance optimisation, observability, and debugging practices to build reliable software and resolve complex production issues.

- Version, document, and publish client libraries with strong semantic-versioning and backwards-compatibility discipline, and contribute to clear integration guidance that enables merchants to adopt and integrate APEXX capabilities successfully.
