Job Description
Job Summary
Seeking a Senior JavaScript Developer focused on frontend component architecture using Next.js/React + TypeScript. You will own the “component layer” between design and content, transforming designs and content models into a smaller, smarter, reusable system. This role is supported by Storybook and automated tests, and shaped in close partnership with designers and content strategists.
Please Note: This is a contract role, approved for 40-hours per week, with an immediate start.
Responsibilities
- Own and evolve the component layer between design and content.
- Decompose designs into reusable, variant-driven components; reduce redundancy and advocate for config variants over new patterns.
- Collaborate with designers to negotiate simplification and gain buy-in for design system improvements.
- Build and maintain a Storybook instance as the living reference for components and states.
- Write automated tests (unit, integration, E2E as appropriate) to enable safe refactoring.
- Shape and refine content models to support robust component architecture, understanding CMS modeling impacts on frontend feasibility.
Requirements
- Deep TypeScript + Next.js/React experience, specifically in frontend systems and component architecture.
- Experience building component-driven sites on headless CMS platforms (e.g., Sanity, Contentstack, Contentful) and understanding content modeling tradeoffs.
- Strong Storybook-first mindset: committed to building stories alongside components from inception.
- Strong testing mindset; with clear opinions on what to test, utilizing Jest/Vitest + React Testing Library (RTL). Playwright/Cypress experience is a plus.
- Ability to identify redundancy in design systems, articulate its implications, and drive simplification initiatives.
- Comfortable collaborating (and constructively pushing back) with designers and content strategists to achieve optimal outcomes.
- Node.js familiarity is a plus (for API routes/tooling), though the core focus remains frontend component architecture.
