Senior Node.js Developer
About the Role
We are building a next-generation AI First CRM workflow automation platform — enabling users to visually create, orchestrate, and execute workflows connecting APIs, data sources, and AI models.
We’re looking for a strong Node.js Developer who can design and implement the core workflow execution engine, node framework, and integration architecture.
Key Responsibilities
- Design and implement backend components for a visual workflow automation platform using Node.js and TypeScript.
- Develop the workflow runtime engine — capable of sequential, parallel, conditional, and human-in-loop execution.
- 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.
Technical Skills Required
Core:
- Strong in Node.js & TypeScript — deep understanding of async/await, streams, events, and error handling.
- Experience with Express.js / Fastify for backend API development.
- 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.
- Understanding of AI/LLM integration into workflows.
- Prior experience building multi-tenant SaaS platforms.
- Cloud experience (AWS / GCP / Azure).
Soft Skills
- 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
- 4+ years of experience in backend development (Node.js).
- 1+ year of experience in building scalable, event-driven or automation systems is preferred.
- Prior contribution to open-source or internal workflow systems is a strong plus.
