Md Node.js

We’re looking for a Backend Engineer (Node.js with Go experience) to grow the server-side of a product for a US-based end client: build new functionality, improve service stability, quickly identify and fix bugs, and ensure reliable data exchange between clients and the server.

Tech split: Node.js (~90%), Go (~10%).

About the role & product

• Core backend stack: Node.js + TypeScript
• Additional: Golang — you should know it and be ready to occasionally write/maintain Go code.
• Database: PostgreSQL
• Infrastructure: AWS (strong familiarity required)

• Communication/IoT: MQTT

  Important: “IoT” here is not about thousands of devices. Think of it as a communication channel between one mobile client, one TV/device, and our server.

• Client requirement (must-have): using the customer-provided Claude (AI) as part of the development process.

Key responsibilities

• Backend development in Node.js/TypeScript (new features + maintenance of existing code).
• Occasional work on Golang components (smaller share, but you should be comfortable with it).
• Bug fixing, troubleshooting, and incident handling (when needed).
• Testing: writing/maintaining tests, validating changes before releases.
• Working with PostgreSQL (queries, optimization, data integrity).
• Working with AWS (deployments/services/environments depending on the current setup).
• Using Claude in daily development (e.g., analysis, preparing changes, reviews, documentation) in line with the client’s guidelines.

Requirements

• Commercial experience in backend development with Node.js and TypeScript.
• Strong understanding and hands-on experience with PostgreSQL.
• AWS: confident knowledge (ability to work with cloud environments and understand common services and approaches).
• Solid basic Golang skills (read/fix/write small parts).
• Experience with or readiness to work with MQTT / message-driven communication.
• Good spoken English (US client).
