Job description

About Us

The OTC derivatives market moves trillions of dollars daily on infrastructure that hasn't fundamentally changed in decades. We're building the platform for the next evolution of financial services.

We're a small team that came from trading, quant, and engineering roles at tier one financial institutions who were previously responsible for creating some of the most innovative products in the market. We are now building a platform which can process the most complex transactions executed across financial markets. We are building this right: delightful experience, modern stack, AI-native architecture.

Our clients are the most sophisticated banks, hedge-funds, and asset managers in the world. The problems are extremely hard, the scale is massive, and we're creating infrastructure that will define how this market operates for decades to come.

Our Tech Stack

Our frontend is built on TypeScript, React, and Next.js with Redux for state management, backed by Python and Java microservices and MongoDB. We are cloud-native employing AWS serverless infrastructure by design.

We have a fully automated SDLC utilizing Github, Vercel and other technologies for rapid and continuous intraday deployment.

About The Role

In this role, you will take meaningful ownership of the UI layer across Float's platform, helping define and deliver the technology that powers our user experience. This is a hands-on role where you will design and implement highly interactive, data-rich interfaces, influence architectural decisions, and ensure we deliver a world-class product experience to institutional finance users. This role is ideal for someone who loves solving deep product challenges, cares about clean and scalable frontend engineering, and wants to take the reins of a rapidly growing codebase.

You’ll have genuine ownership here—not just tickets—with the ability to influence architecture, introduce new best practices, and shape how institutional finance software should work. We hire for impact, velocity, and craft, and we invest in your growth toward technical leadership.

What You’ll Do

• Own major areas of our frontend codebase and influence technical direction as we scale
• Design and implement highly interactive, data-rich user interfaces using React, Next.js, and TypeScript
• Work closely with product, design, and backend engineering to shape requirements and deliver quality features quickly
• Build and maintain reusable component systems, patterns, and documentation for long-term scalability
• Integrate APIs with precision, handling complex data flows and edge cases
• Champion performance, accessibility, TypeScript rigor, and developer experience improvements
• Drive code reviews, architectural discussions, and incremental upgrades to our frontend stack

Requirements

• 2+ years of professional experience building modern frontend applications
• This role is based in-person at our NYC office
• Expertise in React, Next.js, TypeScript, and state management frameworks (e.g., Redux)
• Comfortable taking technical ownership and making decisions that impact product direction
• Strong foundation in UI architecture, performance optimization, and modern component patterns
• Proficiency with API integration (REST/GraphQL), async data handling, and error management
• Experience building and maintaining reusable component systems and documentation
• Strong problem-solving and communication skills

Bonus Qualifications

• Production experience with hybrid rendering (SSR/SSG) using Next.js
• Working knowledge of MongoDB or distributed data models
• Familiarity with automated UI testing (RTL, Jest, Cypress)
• Experience with enterprise UX patterns and multi-user permissions systems
• Comfort integrating AI coding assistants (e.g. Cursor, Claude Code) into your development workflow
• Interest in data visualization and complex modeling workflows
• Familiarity with financial products and ideally complex derivatives
• Prior experience working with institutional clients or within capital markets
