About the job
WHY WE EXIST
Money should flow as seamlessly as data.
In today's world, it often doesn't. With technology advancing, customers are now demanding instant, global, and programmable monetary solutions. HIFI is on a mission to address this gap. Our goal is to make money intrinsically programmable, equipping developers and businesses with the tools necessary to transfer value at the speed of software.
We are fundamentally reconstructing the financial infrastructure of the internet from the ground up.
THE ROLE
As a Senior Frontend Engineer at HIFI, you will spearhead the development of our developer-centric products, which facilitate the interaction of businesses and creators with our platform. This includes everything from the Developer Dashboard to SDKs and integration tools. You will design and implement experiences that simplify complex financial infrastructures, making them intuitive, quick, and user-friendly.
This position demands not only extensive technical knowledge but also a strong sense of product design. You won’t merely execute existing designs; you will have a critical role in shaping them. You will not just roll out features; you will set the standard.
If you engage with it, you take ownership. That’s our mantra.

WHAT WE'RE LOOKING FOR
4+ years of experience in building and deploying high-performance frontend applications in production environments.
Expertise in React, TypeScript, and contemporary frameworks (Next.js, React Native).
Experience in leading architectural decisions and managing design systems and component libraries.
Strong product instincts capable of shaping user experience and influencing product direction.
Proficient in CI/CD, testing frameworks, monitoring, and performance optimization.
