  • Integrate payment gateways (Stripe, Razorpay, etc.) for subscription management.
  • Ensure high availability, security, and scalability of the backend services.
  • Collaborate closely with frontend developers, game engineers, and designers to deliver end-to-end features.
  • Write clean, maintainable, and testable code with strong documentation.
Required Skills & Experience
  • Strong proficiency in Node.js / TypeScript (or Python/Go, if experienced in SaaS).
  • Experience with SaaS product architecture: authentication (OAuth/JWT), multi-tenant databases, subscription models.
  • Hands-on experience with SQL/NoSQL databases (PostgreSQL, MongoDB, Firebase, etc.).
  • Proficiency in cloud platforms (AWS/GCP/Azure) and CI/CD pipelines.
  • Strong knowledge of API security, scalability, and performance optimization.
  • Experience handling file uploads, storage systems (S3/GCS), CDN integration.
  • Understanding of DevOps practices (Docker, Kubernetes, monitoring, logging).
  • Familiarity with payment integrations (Stripe, PayPal, etc.).
Nice-to-Have Skills
  • Prior experience building creative SaaS tools (design platforms, editors, adtech, game engines).
  • Knowledge of WebSockets for real-time collaboration.
  • Experience with serverless architecture (Lambda/Cloud Functions).
  • Familiarity with analytics pipelines for tracking engagement, conversion, and ad performance.
