Sr UI Developer (React & Next JS) Role

Role Overview

As a Sr UI Developer, you'll craft responsive, performant interfaces using React and Next JS, ensuring seamless user experiences across client data platforms. Your work directly impacts business metrics like user engagement and conversion rates by translating design specs into production-ready code. This senior-level position means leading features end-to-end, from prototyping to deployment, in a remote setup that demands self-starters.

Detailed Responsibilities

• Develop and optimize React components for reusable UI libraries in enterprise dashboards.
• Implement Next JS for server-side rendering, improving SEO and load times on data-heavy apps.
• Collaborate with UX designers to refine Figma prototypes into pixel-perfect implementations.
• Integrate APIs for real-time data visualization using libraries like D3.js or Chart.js.
• Conduct code reviews, enforce accessibility standards (WCAG), and mentor junior developers.
• Troubleshoot performance bottlenecks with tools like Lighthouse and React DevTools.
• Deploy updates via CI/CD pipelines, often using Vercel or AWS for Next JS apps.

Day-to-Day Workflow

Your day kicks off with a 30-minute stand-up in Slack or Zoom, syncing on priorities with the frontend team. Mornings involve deep coding sprints—building components or refactoring hooks—broken by quick design huddles. Afternoons shift to testing, PR reviews, and client demos, wrapping with planning for tomorrow's tasks.

Expect 60% hands-on development, 20% collaboration, and 20% learning new tools like Tailwind CSS integrations. Remote tools like Jira, GitHub, and Figma keep everyone aligned, with occasional video calls for Northfield-area folks.

• Styling: Tailwind CSS, Styled Components, CSS-in-JS.
• Build/Deploy: Vercel, Webpack, ESLint, Prettier.
• Testing: Jest, React Testing Library, Cypress for E2E.
• Design/Collab: Figma, Storybook for component docs.
• Other: Node.js, GraphQL/REST APIs, Docker for local dev.

Skills and Requirements

Technical Skills

You need strong proficiency in React and Next JS, including hooks, context API, and SSR/SSG patterns. Familiarity with state management (Zustand or Redux) and performance optimization like memoization is essential. Bonus points for TypeScript mastery, accessibility practices, and experience with data viz libraries.

Soft Skills

Clear communication shines in remote settings—articulating technical decisions via PR comments or client updates. Problem-solving under ambiguity is key, as client needs evolve mid-sprint. Team players who thrive in feedback loops and mentor juniors will fit seamlessly.

Senior status requires 4+ years in frontend dev, with a portfolio showcasing 3-5 React/Next JS projects (live links preferred). Side projects or open-source contributions count heavily; GPA matters less for experienced hires. Demonstrate impact via metrics like "Reduced load time by 40% on e-commerce app."
