About This Role

There is an enormous gap between the technology available in Silicon Valley and what the average small business owner in America actually has access to. The pharmacist in rural Louisiana. The auto dealer in the midwest. The vet clinic owner who has been doing their books the same way for twenty years. They are running the businesses that hold American communities together, and the software serving them has never reflected how important they actually are.

Affiniti is closing that gap. We're building the financial operating system for small businesses across America, and the frontend is the bridge. Every dashboard you ship, every interaction you refine, every millisecond you shave off a load time is technology finally reaching the people who needed it most and never got it.

If you want to write code that matters beyond the product itself, this is that opportunity.

(Location and experience adjusted)

BENEFITS

• Reimbursed Relocation
• Free Lunch and Dinner (In NYC)
• Paid Technology Equipment Set Up
• Health, Dental, and Vision Insurance Fully Covered

Key Responsibilities

• Own the frontend architecture: component systems, state management, performance budgets, and the foundational decisions that determine how the product scales visually and functionally
• Own the full stack when needed: you're comfortable writing backend logic, hooking into APIs, and tracing a bug from the database to the browser
• Build dashboards and data-rich interfaces that make complex financial information feel simple. The kind of UI where users instantly know what to do and why it matters
• Obsess over the details: load times, interaction latency, pixel precision, and the micro-decisions that separate a good interface from one people actually love using
• Collaborate directly with design to push beyond mockups. Challenge constraints, propose better patterns, and close the gap between what's designed and what ships
• Translate ambiguous user needs into clean, maintainable implementations, and advocate for the user in every technical decision

Qualifications

• Full-stack capability: you can own a feature end-to-end without needing a backend engineer to hold your hand
• 2+ years of production engineering experience. Early-stage startup experience strongly preferred
• Deep fluency in TypeScript and React. You have strong opinions about component architecture, rendering behavior, and state
• A genuine eye for design: you notice when spacing is off, when a color is wrong, and when an interaction feels slightly broken — and you fix it without being asked
• Ability to build and maintain complex, data-rich dashboards with real performance constraints
• Strong at moving fast without accumulating the kind of frontend debt that makes codebases painful to work in six months later
