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.
