  • Build a modular node / plugin architecture (like n8n nodes) for API connectors, data operations, and logic functions.
  • Implement a secure sandbox for executing user-defined code / functions.
  • Develop RESTful APIs and WebSocket interfaces for the workflow editor (frontend).
  • Integrate with databases (MongoDB / Postgres) and manage workflow persistence and execution logs.
  • Work with Redis / BullMQ (or similar) for distributed workflow execution and queue management.
  • Ensure high performance, fault tolerance, and scalability across multi-tenant environments.
  • Collaborate closely with frontend and DevOps teams to ensure smooth integration and deployment.

  • Hands-on with database ORM frameworks (TypeORM, Prisma, Sequelize).
  • Strong understanding of workflow orchestration concepts — DAGs, triggers, and execution contexts.
  • Familiar with Redis / BullMQ / RabbitMQ / Kafka for distributed task management.
  • Good understanding of sandboxing techniques (vm, isolated process execution, or containers).
  • Experience designing plugin systems / dynamic module loading (custom nodes or extensions).
  • Knowledge of Webhooks, Schedulers, API Integrations (REST, OAuth2, WebSocket, etc.) .
  • Experience with Docker / containerization for deployment and scaling.
  • Experience in AWS Lamda, AWS EKS cluster deployment.

    • Bonus Skills :

  • Exposure to n8n, Temporal.io, Airflow, or similar automation frameworks .
  • Knowledge of frontend frameworks (ReactJS) for workflow editors.

  • Excellent problem-solving and system design thinking.
  • Collaborative mindset — works well with architects, DevOps, and product teams.
  • Self-driven to explore open-source projects and implement best practices.
  • Strong documentation and code quality discipline.

    • Experience
