About Vijay Sales
Vijay Sales is a consumer electronics and appliances retailer, selling through its stores across India, its website and its app.
Our technology team builds the software the business runs on: order management, customer support automation over WhatsApp, reviews and ratings, and the dashboards our operations teams use every day.
The role
We are hiring full stack engineers who can take a feature from spec to production across React, Node.js and MongoDB.
You will work on customer-facing and internal products, often both in the same week. One sprint may be a review submission page used by customers on their phones. The next may be an API that pulls order status from our order management system for the support bot.
We are looking for engineers with 3 to 6 years of experience who are comfortable owning both the front end and the back end of what they ship.
What you'll do
- Build responsive, mobile-first interfaces in React using our in-house UI component libraries.
- Design and build REST APIs and background services in Node.js.
- Model data in MongoDB and keep queries fast as collections grow.
- Integrate with the systems the business runs on: order management, ERP, point of sale and ticketing.
- Build messaging flows over WhatsApp, email and SMS, including delivery tracking, retries and fallbacks.
- Work with the conversational AI team to expose order, invoice and support actions to the customer support bot.
- Write tests, review code and own your features in production, including monitoring and fixing what breaks.
- Work directly with product and operations teams to turn a business problem into a working release.
Our stack
React, Node.js and MongoDB are the core. Everything else in the table is what you will connect to or build alongside.
- Front end: React, with Vijay Sales' in-house UI component libraries
- Back end: Node.js services and REST APIs
- Database: MongoDB
- Messaging: WhatsApp Business, Amazon SES for email, RCS and SMS as fallback
- Conversational AI: LangChain and Rasa, behind the customer support bot
- Business systems: Order management (OMS), ERP, POS, Ticketing Systems
What we're looking for
- 3 to 6 years of professional experience building and shipping web applications.
- Strong JavaScript and TypeScript fundamentals: async patterns, the event loop, modules, error handling.
- Solid React skills: hooks, state management, component design, performance on low-end mobile devices.
- Hands-on Node.js experience: building REST APIs, authentication with JWT, role-based access, input validation.
- Working knowledge of MongoDB: schema design, indexing, aggregation pipelines.
- Experience integrating third-party APIs and webhooks, and handling their failures gracefully.
- Comfort with Git, code review, automated tests and CI/CD.
- Clear written and spoken communication. You will talk to operations and business teams, not only engineers.
Nice to have
- Experience with the WhatsApp Business API, Gupshup or similar messaging platforms.
- Exposure to LLM application development: LangChain, retrieval, tool calling, or bot frameworks such as Rasa.
- Background in retail, e-commerce or order management systems.
- Experience integrating with ERP or POS systems.
- Familiarity with AWS, Redis and message queues.
- React Native or other mobile app experience.
Why join and how to apply
- Your work reaches real customers and store teams quickly. There is very little distance between a release and the people who use it.
- You own features end to end, from the first conversation with the business team to production.
- You get hands-on exposure to conversational AI and LLM-based products alongside core full stack work.
