NodeJS Engineer (Database & Data Pipelines)

As a Node.js Developer with a strong focus on databases at Smartico.ai, you will be at the core of building and maintaining high-performance data processing pipelines.

You’ll work across multiple database technologies—both relational and non-relational—while designing efficient backend services that connect with data warehouses and external systems.

Key Responsibilities

• Backend Development: Architect, develop, and maintain scalable backend services using Node.js and TypeScript.
• Data Pipelines: Design and implement data ingestion and transformation pipelines, ensuring reliability and scalability across large datasets.
• Database Expertise: Work with relational (PostgreSQL, MySQL) and non-relational (MongoDB, Redis, etc.) databases, as well as data warehouses (BigQuery, Redshift, Snowflake).
• API Development: Build and integrate RESTful APIs and WebSockets to support real-time and batch data flows.
• Performance & Optimization: Optimize query performance, storage efficiency, and backend throughput.
• Security & Compliance: Apply best practices for data integrity, access control, and secure communication.
• Collaboration: Partner with frontend developers, product teams, and data engineers to deliver seamless solutions.

Required Skills & Experience

• 5+ years of experience in backend development with Node.js.
• Proficiency in TypeScript and modern Node.js frameworks (Express.js, NestJS, or similar).
• Strong understanding of asynchronous programming and event-driven architecture.
• Solid experience with SQL databases (PostgreSQL, MySQL) and query optimization.
• Exposure to NoSQL databases and data warehouses for large-scale data handling.
• Hands-on experience designing scalable, high-performance applications.
• Good understanding of REST APIs.
• Strong knowledge of Git and best practices for version control.
