The Role

We are seeking a Senior Frontend Developer to lead the frontend implementation of our B2C E-commerce Shop and B2B Vendor Portal. You won't just be building landing pages; you will be architecting a high-conversion retail engine. This includes complex inventory dashboards, predictive reordering interfaces, and supplier management tools. You will work within a Multi-Repo architecture, consuming and contributing to an internal shared components library.

What You'll Do

• Component Architecture: Actively contribute to the shared internal Next.js components library based on shadcn/ui and TailwindCSS. You will build reusable components (Product Cards, Multi-select Filters, Inventory Grid, DataTables) used by all portals.
• Complex State Management: Manage server state using TanStack Query (caching, optimistic updates) and client state using Zustand.
• Design-to-Code: A keen eye for detail. You can take Figma designs and translate them into pixel-perfect, responsive layouts.
• High-Performance Data Grids: implementation of TanStack Table (Headless UI) to render, filter, sort, and paginate a large amount of records without performance lag.
• Form Engineering: Build forms using React Hook Form and Zod. You will implement strict client-side validation logic that mirrors backend constraints.
• Security & Auth: Handle authentication flows, ensuring strict RBAC (Role-Based Access Control) visibility for UI elements.
• Performance Optimization: Ensure "Cold Starts" under 3s and lightning-fast transitions. You understand how to optimize Next.js Server Components (RSC) and implement effective code-splitting.
• Quality Assurance: Write tests for critical user flows to ensure zero regressions in production.

What We're Looking For

• 5+ years of professional experience building React/Next.js applications.
• TypeScript: You don't just use any. You use Generics, Utility Types, and Zod inference to ensure type safety from the API response to the UI component.
• Modern CSS: Mastery of TailwindCSS. You understand the utility-first philosophy and how to configure a design token system.
• Library Experience: Hands-on experience with TanStack Query (React Query), TanStack Table, and React Hook Form.
• Design System Mindset: Experience working with component libraries (Radix UI, Headless UI, or building your own) is crucial.
• Performance Tuning: You know how to debug re-renders, use useMemo/useCallback correctly, and code-split heavy bundles.
• API First: Work closely with Backend Engineers to consume OpenAPI/Swagger generated types, ensuring the frontend remains in sync with our Java Spring Boot microservices.
• Domain Knowledge: Experience in E-commerce, Fintech, or Retail (Marketplaces, Warehouse, and Inventory Management systems) is a massive plus.
• Language: Fluent English is mandatory. Spanish is a plus for understanding the context of the systems you are building and communicating with the client.

What To Expect

• Flexibility - We have standard 40-hour work weeks. While our agency working hours are from 9 am to 7 pm CET, you’ll have the freedom to work flexible hours and maintain a healthy work-life balance. Just make sure the majority of your working hours fall within that time frame.
• Remote work & Tooling - We operate as a fully remote team. We utilize HubStaff for time tracking and work transparency. We value trust and output, and these tools help us streamline administrative overhead.
• Culture - We value collaboration, openness, a willingness to learn, lead, and a curious nature. Our approach encourages mistakes as long as we are willing to learn from them, fostering a culture where growth comes from understanding and overcoming challenges.
• Autonomy and responsibility – You’ll be trusted to get things done efficiently and effectively.

Hiring Process

1. Application review - We’ll review your experience, background, and overall fit for the role.
2. Video Call with HR - Initial conversation about fit, availability, and expectations
3. Second interview with Leadership - If there is a strong match after the first conversation, we’ll invite you to a second interview with the Leadership team. This discussion will focus primarily on cultural fit, ownership, communication, and the way you approach collaboration and problem-solving. We may also revisit a few technical topics if anything needs additional clarification.
4. Welcome to Afternow!
