Role overview

A senior frontend engineering position focused on building consumer-facing applications within a fully distributed, remote-first consumer finance organization. The role centers on designing, shipping, and owning React-based experiences and the UI infrastructure that supports a digital lending platform, with a strong emphasis on modern, AI-assisted engineering workflows.

Responsibilities

• Design, build, and own production React applications, including hooks, component architecture, and UI SDKs used by other engineers.
• Drive engineering efficiency through AI-driven coding agents and agentic workflows that autonomously build, test, and ship complex frontends at scale.
• Lead the full software development lifecycle: scoping, design, development, automated testing, delivery, and ongoing maintenance of features.
• Collaborate with product managers, designers, business owners, and engineers to identify the right solutions and shape functional and technical specs.
• Implement automated frontend testing for critical components and user workflows, upholding code quality and reliability standards.
• Mentor other frontend engineers, address technical debt, and evolve tooling to reduce operational load across the team.

Requirements

• 5+ years building production React applications at scale, with deep expertise in React, hooks, and component architecture.
• Production experience with ReactJS, CSS, GraphQL, JavaScript, and Node.js, plus working knowledge of Python and Java.
• Track record delivering scalable, highly available consumer applications, ideally across the full technology stack.
• Familiarity with AWS services such as EC2, S3, Lambda, and API Gateway.
• Strong testing discipline and the ability to scope, prioritize, and unblock work across ambiguous technical and business projects.
• BA or Master's degree in Computer Science or a related field, or equivalent practical experience.

Nice to have

• Experience with AI coding agents and agentic development workflows applied to React applications.
• Background building UI-based SDKs for downstream developer consumption.

Benefits and work setup

• Base salary range of $140,000–$160,000 USD, plus eligibility for an annual bonus.
• Medical, dental, and vision insurance; 401(k) with matching; company-paid short- and long-term disability and life insurance.
• Generous PTO including sick leave, vacation, and volunteer time, plus 12 weeks of paid parental leave.
• Monthly remote-work tech stipend and a 100% fully distributed workforce model.
