Requirements

• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
• 3+ years of professional software development experience with a strong emphasis on frontend or full-stack web engineering.
• Proficiency with AI-assisted development tooling (e.g., Claude Code, Cursor) demonstrated by at least one year of daily use, in addition to a commitment to an AI-first engineering culture that leverages these tools to maximize code quality, test coverage, and engineering velocity.
• Proficiency in JavaScript and TypeScript, with hands-on experience building React/Next.js applications.
• Demonstrated ability to independently ship well-tested, production-quality features with minimal oversight.
• Strong communication and collaboration skills, with a track record of working effectively across Product, Design, and Engineering.

Nice To Haves

• Experience building or contributing to browser extensions using the WebExtensions API (Chrome, Safari, or Firefox).
• Familiarity with state management libraries (e.g., Zustand, Redux) and modern frontend tooling (Vite, webpack, etc.).
• Exposure to Ruby on Rails or another server-side framework used in full-stack feature development.
• Experience integrating with affiliate networks, e-commerce platforms, or coupon/deal systems.
• Understanding of authentication flows (OAuth2, OpenID Connect) and how identity interacts with consumer web experiences.
• Comfort working in a fast-moving product environment with iterative releases and A/B testing.
• Familiarity with CI/CD pipelines, automated testing frameworks, and performance profiling tools.
• Startup or high-growth company experience with a strong bias toward execution and ownership.

• Code Quality & Engineering Craft: Write high-quality, maintainable code with strong test coverage, following team best practices around code reviews, CI/CD, and documentation. Contribute to the health of the codebase by identifying and addressing technical debt and improving shared components.
• Third-Party Integrations: Integrate with e-commerce platforms, affiliate networks, and third-party APIs to extend the reach and functionality of the Shop experience. Proactively raise issues or opportunities discovered during integration work.
• Security & Privacy Best Practices: Apply security and privacy best practices in all feature work, with particular attention to browser extension permissions, data handling, and authenticated identity flows.
