We are looking for a Front-end Developer to join one of SEP’s fast-growing ventures. In this role, you will work on building fast, scalable, and user-centric interfaces for an e-commerce platform, ranging from internal merchant dashboards to customer-facing storefronts.

Key Responsibilities:

• Design, develop, and maintain frontend applications using React and Next.js.
• Build reusable UI components and contribute to a shared design system.
• Implement responsive and cross-browser user interfaces.
• Integrate frontend applications with RESTful and/or GraphQL APIs.
• Optimize performance with a strong focus on Core Web Vitals, SEO, and user experience.
• Effectively leverage Next.js features such as SSR, ISR, Image Optimization, and App Router.
• Implement and manage state management and data-fetching strategies (e.g., Zustand, Redux Toolkit, TanStack Query, SWR).
• Write and maintain unit and integration tests for critical user flows (e.g., checkout).
• Collaborate closely with backend, product, and design teams.
• Design and evolve the frontend architecture and technical roadmap.
• Define and enforce frontend standards (TypeScript, linting, testing, code structure).
• Lead code reviews and mentor team members.
• Balance technical quality with delivery speed in a startup environment.
• Own features end-to-end, from design decisions to production performance.

Requirements:

• +5 years of professional experience in frontend development.
• Strong proficiency in React and solid production experience with Next.js.
• Proficiency in TypeScript and modern CSS frameworks (preferably Tailwind CSS).

• Good understanding of web performance, accessibility (a11y), and SEO.
• Familiarity with Docker (at least in development environments).
• Strong collaboration and communication skills in product-driven teams.
• Technical Stewardship: Define the frontend roadmap, establish coding standards (TypeScript, Linting, Testing), and ensure the team follows them.
• Growth & Coaching: Mentor mid-level developers through deep code reviews and pair programming, fostering a culture of "vibe coding" and high-velocity shipping.

Nice to Have:

• Experience with AI-augmented development tools (Vibe Coding) (e.g., Cursor, Windsurf, v0.dev)
• Experience with animations and micro-interactions (e.g., Framer Motion)
• Experience building SaaS dashboards or e-commerce platforms.
• Familiarity with CI/CD pipelines and modern deployment platforms.
