About the Role

We are hiring a Senior Frontend Developer to build and evolve the web experience at the heart of our platform. You will own significant frontend features end to end, caring as much about the problem being solved for the user as the code that solves it. You will build in React and TypeScript, partnering closely with product and design to turn complex business problems into interfaces that feel simple. As one of our senior frontend engineers, you will also help modernize our frontend tooling and practices, and raise the bar for quality across the team. You will set direction on frontend patterns and architecture while staying close to the code: shipping features alongside the team, reviewing pull requests, and collaborating with engineers across the stack. The decisions you make show up directly in the product.

Responsibilities

Build, review, and test frontend features end to end in React and TypeScript, contributing directly to the product our customers use every day.
Partner closely with product and design to translate business problems into intuitive, polished user experiences.
Collaborate with our backend engineers to define clear API contracts and deliver features that work seamlessly across the stack.
Help modernize our frontend tooling, standards, and reusable components, raising the bar for quality across the team.
Build and evolve the shared component library that powers a consistent, accessible experience across the product.
Optimize the performance of data-dense interfaces, from large tables and lists to real-time views.
Drive technical discussions and contribute to frontend architecture decisions.
Work closely with Product to validate ideas and build prototypes when needed.
Use AI tools to accelerate your work, and share effective practices with the team.

Requirements

5+ years of professional frontend engineering experience building production web applications.
Deep expertise in React and TypeScript, on a strong foundation of core JavaScript.
A product mindset: motivated by solving real problems for users, not just shipping tickets.
A track record of owning features end to end and making sound architectural tradeoffs.
Experience with modern state management, particularly handling server state and data fetching in complex applications.
Experience optimizing the performance of data-dense interfaces and keeping large, interactive UIs fast.
Experience building or contributing to a shared component library or design system.
A solid grasp of web accessibility standards and a commitment to building inclusive interfaces.
Effective collaboration skills across disciplines, particularly with design and backend engineering.
Excellent communication skills, with the ability to explain technical concepts clearly to a range of audiences.
Eagerness to use AI tools to accelerate engineering work and a tendency to share effective practices with the team.
Willingness to take on some backend development, or to learn it as needed.
Experience modernizing or migrating a legacy frontend codebase.
A sensibility for the security, audit, and reliability expectations of regulated industries (finance or similar).
