Designer Engineer

WHY WE EXIST

Money should move as easily as data.

It doesn't today. Technology is finally catching up to the need — customers expect instant, global, programmable money. HIFI exists to fix that. Our mission is to make money programmable by default, and to give developers and businesses the tools to move value at software speed.

We're rebuilding the financial plumbing of the internet from the ground up.

THE ROLE

As a Design Engineer at HIFI, you will own the intersection of design and engineering — building the interfaces, interactions, and experiences that make complex financial infrastructure feel simple and inevitable.

You will concept, prototype, and ship production-quality UI across our web presence and product surfaces. You will translate design intent into code with precision, and push what's technically possible back into the design process. You will build the tools and experiences that help developers and businesses understand what programmable money actually feels like.

This isn't a role for someone who hands off to engineers or waits for design files.

If you touch it, you own it. That's how we work.

WHAT YOU'LL BUILD

• Concept, prototype, and ship new web experiences that communicate the value of HIFI's products with clarity and craft.

• Build production-quality UI components and interactions — from pixel-perfect layouts to smooth, meaningful animations.

• Own the quality of UI implementation across the product, closing the gap between 90% and 100%.

• Create reusable components and contribute to a design system that lets the team move faster without sacrificing quality.

• Collaborate directly with engineers and product to define what's possible — and then build it.

• Rapidly prototype new concepts to validate ideas before full implementation.

WHAT WE'RE LOOKING FOR

• 4+ years of front-end development or creative technology experience at a product-driven company.

• Advanced command of modern HTML, CSS, and TypeScript.

• Strong proficiency with React, with a focus on interactions, animation, and performance.

• An eye for design detail — typography, layout, proportion, motion — not just functional UI.

• A portfolio that proves it: design systems, microsites, interactive tools, CSS experiments, or whatever shows us how you think.

• Experience shipping polished, public-facing products that work across browsers and devices.

• A communicator who works well across design, engineering, and product without needing a translator.

NICE TO HAVE

• Familiarity with WebGL, Three.js, or canvas-based rendering.

• Experience with A/B testing, accessibility auditing, or performance optimization.

• Background in fintech, developer tools, or technically complex products.

• Prior early-stage startup experience — you know what building from zero actually means.

COMPENSATION & BENEFITS

The expected salary range for this role is $135,000 - $160,000 USD. However, the starting base pay will depend on a number of factors including the candidate’s location, skills, experience, market demands, and internal pay parity. Depending on the position offered, equity and other forms of compensation may be provided as part of a total compensation package.

We offer full health coverage (medical, dental and vision) and unlimited PTO.

We're changing how modern business moves value.

If that sounds like the problem you want to spend the next chapter of your career on, we'd love to meet you.
