Job description

About Darkful

Darkful is a modern SaaS platform built to power 3PL (Third-Party Logistics) and dark-store fulfillment operations for e-commerce brands. It enables local and fast order fulfillment by connecting online stores with warehouses, providing an intuitive yet powerful solution for small and mid-sized 3PL providers.

Our MVP will focus on integrations with Salla and Zid, delivering a bilingual (Arabic/English) ecosystem that includes multiple portals for 3PLs, merchants, and admins.

Role Overview

We’re looking for a Full-Stack Developer to lead the end-to-end development of Darkful — from architecture design to launch. This role requires someone who can work independently, implement clean and scalable code, and translate product logic into a working, production-ready SaaS platform.

You will build and connect all modules of Darkful, including authentication, integrations, order and inventory management, API syncing, and the multi-portal user experience.

Key Responsibilities

• Develop and deploy the full Darkful platform (frontend, backend, and database).
• Implement multi-role access (3PL, merchant, admin) with secure authentication and RLS logic.
• Develop core 3PL workflows: receiving, picking, packing, returns, inventory tracking, and order routing.
• Integrate with Salla and Zid APIs for real-time syncing of orders, products, and stock levels.
• Build bilingual (Arabic/English) UI with dynamic language toggle.
• Ensure responsive and smooth UX across all portals.
• Create scalable database structure and clean API layer.
• Handle deployment, debugging, and performance optimization.
• Collaborate closely with the product owner for weekly sprints and feature rollout.

Requirements

• Proven experience in full-stack SaaS development (frontend + backend + database).
• Strong understanding of REST APIs, webhooks, authentication, and data models.
• Skilled in JavaScript/TypeScript, React or similar frameworks, and modern backend frameworks (e.g., Node.js, Python, Express, or equivalent).
• Experience with multi-tenant or role-based systems.
• Knowledge of database design, preferably PostgreSQL or similar.
• Familiarity with e-commerce or 3PL systems (inventory, order fulfillment, logistics) is a strong plus.
• Ability to independently manage product development from concept to deployment.
• Fluent in English; Arabic understanding is a plus.

Preferred Skills

• Experience integrating third-party APIs (especially e-commerce platforms).
• UI/UX understanding for clean, modern, bilingual web apps.
• Experience in building scalable MVPs and optimizing for performance.
• Basic knowledge of DevOps, testing, and version control (Git).
