Job description

Freelance E-commerce Full Stack Developer (MERN) — Core Team Track

📍 Remote | Part-Time / Freelance (Core Team & Equity Track)


We’re building something extraordinary — a next-generation digital commerce platform that seamlessly merges shopping, rewards, and engagement.


Our vision is simple yet powerful:

To build an ecosystem where users earn through engagement, brands grow through interaction, and technology powers transparency and trust.


We’re looking for a senior MERN Stack Developer who’s not just a developer but a builder and thinker — someone ready to lead technology development from 0→1, help shape the architecture.

This is a milestone-based compensated role during Phase 1, transitioning into a core founding position for the right person.


Your Role

You’ll own the entire technical build of this ecosystem — from backend architecture to front-end execution — collaborating directly with the founder to bring the product vision to life.


Key Responsibilities

  • Architect, develop, test, and deploy a complete e-commerce + rewards ecosystem (Backend and Admin) using the MERN Stack and mobile app using React Native/ Flutter
  • Build and integrate wallets, reward engines, and affiliate systems with scalable APIs.
  • Integrate coupon and cashback ecosystems (e.g., GrabOn, CashKaro, etc.) using postback/S2S mechanisms.
  • Develop vendor, user, and performance dashboards with analytics insights.
  • Ensure system security, scalability, and modularity from Day 1.
  • Manage API integrations (payments, wallets, partners) and cloud deployment.
  • Maintain clean, well-documented, and extensible codebases.


Required Skills & Experience

✅ MERN Stack Expertise: 5+ years of solid experience in MongoDB, Express, React, and Node.js.

✅ E-commerce Architecture: Proven track record in building end-to-end commerce or marketplace systems.

✅ Reward / Affiliate Systems: Understanding of affiliate, coupon, cashback, or postback integrations.

✅ Cloud & DevOps: Proficiency in AWS/GCP, containerization, and CI/CD pipeline management.

✅ Security & Data Handling: Role-based access, encryption, and secure authentication workflows.

✅ Scalability & Performance: Experience designing modular, high-availability systems.

✅ Mobile-first Thinking: Familiarity with React Native or Flutter integration.

✅ Ownership Mindset: Ability to work independently and think beyond the code — into product, growth, and impact.


Must have Skills

  • Experience with gamification, wallet logic, or multi-level incentive systems.
  • Background in microservices, serverless functions, or distributed systems.
  • Understanding of reward tracking, affiliate postbacks, and analytics integrations.
  • Startup experience or direct collaboration with founders.
