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.
What youāll work on
- Build features from end to end. Translate product requirements into working interfaces, backend services and database changes, and follow them through testing and release.
- Create responsive web experiences. Develop reusable React and Next.js components, connect them to APIs, and handle forms, loading states, errors and accessibility across screen sizes.
- Develop dependable APIs. Build modular Node.js services with NestJS, Fastify and related frameworks, with clear contracts, input validation, authentication, authorization and consistent error handling.
- Design and improve data models. Work with PostgreSQL and MySQL for relational data, MongoDB for document models and Neo4j for connected data. Write efficient queries, use appropriate indexes and manage schema changes carefully.
- Integrate systems and workflows. Connect third-party services and internal APIs, manage asynchronous operations, and account for failures, retries and data consistency.
- Make quality part of delivery. Write meaningful unit and integration tests, review code, reproduce bugs and document API behavior and technical decisions.
- Improve performance and security. Investigate slow pages and queries, troubleshoot service errors, and apply secure coding practices to protect application data.
- Work closely with the team. Discuss trade-offs with designers and developers, break work into manageable tasks, and communicate progress and blockers clearly.
What youāll bring
- A solid understanding of JavaScript or TypeScript, asynchronous programming and how web applications communicate over HTTP.
- Hands-on experience building React or Next.js interfaces and Node.js APIs, with familiarity with NestJS, Fastify or similar frameworks.
- An understanding of SQL, database relationships and querying, along with an interest in document and graph databases.
- Comfort with Git, code reviews, debugging and testing your work before handing it over.
- A practical approach to problem-solving, willingness to learn and ownership of the features you build.
Bonus skills
Helpful experience, rather than prerequisites for applying.
- CI/CD pipelines: Automating builds, checks, tests and deployments, working with environment-specific configuration, and understanding release and rollback workflows.
- Jenkins: Creating or maintaining Jenkinsfiles, organizing pipeline stages, handling credentials securely and diagnosing failed builds.
- AWS: Deploying or supporting applications using services such as EC2, S3 and RDS, with awareness of IAM permissions, networking and CloudWatch logs.
- Nginx: Configuring reverse proxies, routing requests to application services, setting up HTTPS, and troubleshooting timeouts, upload limits and access logs.
