About HyperFi
We're building the kind of platform we always wanted to use: fast, flexible, and built for making sense of real-world complexity. Behind the scenes is a robust, event-driven architecture that connects systems, abstracts messy workflows, and leaves room for smart automation. The surface is clean and simple. The interactions are seamless and intuitive. The machinery underneath is anything but. That's where you come in.
We're a well-networked founding team with strong execution roots and a clear roadmap. We're backed, focused, and delivering fast.
We're looking for a Senior Frontend Software Engineer to join early. Someone who's as comfortable building polished, production-ready interfaces as they are shaping the architecture underneath them. You'll work side-by-side with the Tech Lead, CTO, and product team to bring complex flows to life with clean, intuitive UI -- and help define the frontend foundation this platform will grow on.
What You'll Do
Own key parts of the frontend codebase -- from routing and state management to components and accessibility
Build intuitive, high-quality interfaces using modern React + frontend development practices
Collaborate with backend engineers to integrate APIs and event-driven data flows
Help define and evolve design patterns, component libraries, and UI architecture
Make meaningful product decisions alongside design, product, and engineering leads
Write code that's fast, clean, and built to be read and extended
Design and implement clean, modern UI with an eye for detail -- keeping up with current best practices in web design, layout, and styling
Tech Stack (So Far)
React 19
TypeScript (strong typing encouraged)
Playwright + unit tests
GitHub Actions for CI/CD
REST & gRPC API integration
Event-driven data flows (via WebSocket or polling, depending on path)
The stack is lightweight but real -- and open to your input.
What We're Looking For
6-8 years of frontend experience, with serious React chops
Deep understanding of component-driven architecture, hooks, and state management
Experience working on multi-page apps with complex workflows
Comfortable consuming APIs and working closely with backend engineers
Strong intuition for good UX -- even if you're not "a designer"
Clear communicator who can thrive in async-native teams
Bonus If You
Have worked on design systems or component libraries
Care about performance, accessibility, and fine UX details
Have built staging environments or preview deploys
Can debug across the stack, not just in the browser
Can show us a project where UX and engineering came together well
Location & Compensation
Must be based in San Francisco, Las Vegas, or Tel Aviv
Full-time role with competitive comp
Flexible hours, async-friendly culture, engineering-led environment
