Description

Build and maintain customer-facing frontend experiences for live online auctions, delivering features end-to-end while improving performance, reliability, and maintainability. You’ll refactor legacy UI (Backbone, Handlebars/jQuery) to reduce technical debt and drive frontend architecture and standards. You’ll use approved AI coding tools (Claude/Claude Code) as a force multiplier with careful review, security, and data protection.

Responsibilities

• Ship end-to-end frontend features across the platform (implementation through testing and deployment)
• Refactor legacy areas and make pragmatic incremental improvements to reduce technical debt
• Own frontend reliability and performance by diagnosing production issues and improving UX
• Propose frontend patterns, tooling, and conventions to improve developer experience and long-term maintainability
• Use AI tools to plan, build, test, debug, review, and document work—verifying outputs before shipping
• Share effective AI workflows and help teammates adopt AI-assisted practices safely
• Collaborate via pairing, code reviews, and cross-time-zone communication
• Mentor engineers and provide technical guidance
• Partner with Product and Design to clarify requirements, scope, and tradeoffs

• Ability to work in and modernize legacy codebases (Backbone, Handlebars, jQuery)
• Testing discipline: React Testing Library unit tests and Cypress end-to-end tests
• Daily hands-on use of AI coding tools (Claude/Claude Code preferred) and practical understanding of LLM behavior and limitations
• Safe data-handling judgment when using AI (no credentials/customer/personal data in prompts; use approved tools)
• Strong technical judgment for long-term project health
• Collaborative mindset with pairing and code reviews
