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.

Required Skills/Experience

• 3-4 years of experience designing and/or developing web-based applications using JavaScript, Node, React, Angular, etc
• Strong understanding of JavaScript, browsers, mobile platforms, and real-time communication.
• Problem solving skills with data structures and algorithms.
• Hands-on experience developing responsive web applications and scalable backend systems.
• Strong experience in integrating third-party applications, APIs, and external systems.
• Ability to design, develop, and manage integrations between different platforms and systems.
• Hands-on experience using AI-powered development tools such as ChatGPT, Claude, GitHub Copilot, Cursor, or similar tools for coding, debugging, testing, and improving development productivity.
• Ability to learn and adapt to alternative technologies based on project requirements.
• Experience in the product development lifecycle, including prototyping, development, testing, hardening, and deployment.

Additional Skills/Experience  

• Experience with NoSQL databases such as MongoDB and Cassandra.
• Experience with UI component libraries and other popular JavaScript libraries and frameworks such as Vue.js.
• Eagerness to participate in product functionality and user experience design.
• Excellent group facilitation and communication skills, both verbal and written.
• Familiarity with i18n and the latest trends in UI/UX design.
• Experience implementing payment gateways applicable across different countries.
• Understanding of API integrations, authentication mechanisms, and data exchange between systems

Education Requirement

• B.Tech/M.Tech in CSE/IT/AI/ML only.

Roles and Responsibilities

• Build features across the stack — Implement product features that span the React frontend, the GraphQL federation, the Node.js microservices, and the underlying Postgres and ClickHouse stores.
• GraphQL federation work — Add types, resolvers, and subgraph capabilities to the federated Platform API. Keep subgraph boundaries clean. Respect RBAC enforcement at the federation layer.
• Developer experience surfaces — Lift NPS through intuitive UI/UX, fast onboarding, in-browser testing, clear error states, code-snippet generation, and fast time-to-first-successful-call.
• Billing and commerce features — Ship subscription, plan, invoice, payout, and overage features that touch Stripe / PayPal webhooks, the billing state machine, and the usage ledger.
• API catalog and discovery — Improve marketplace search and the API listing experience, including the ranking signals that flow in from the analytics and search stack.
• Observability and quality — Instrument every feature you ship — logs, traces, and metrics are part of the definition of done, not a follow-up ticket. Write the alerts that page you, not someone else.
• Testing discipline — Own unit and integration tests for everything you ship; contribute to the end-to-end and contract test suites that protect the federation and the billing path. A feature without tests is not done.
• On-call and incident response — Take part in on-call rotations; investigate proxy errors, GraphQL federation timeouts, and billing webhook anomalies. You build it, you run it.
• LLM-assisted engineering — Use LLM-based coding and agentic tooling to evolve how features are shipped, reviewed, and tested.

What Success Looks Like

•  Features you ship measurably improve activation, time-to-first-successful-call, and developer NPS quarter over quarter.
• The GraphQL federation surface you touch stays fast, well-typed, and intuitive for the next engineer.
• Billing, subscription, and overage flows you build are accurate, auditable, and replayable — providers and consumers trust the numbers.
• ou ship at a confident cadence — PRs land daily, deploys are routine and boring, regressions are rare.
• You leave the code, the docs, and the tests in better shape than you found them.

What You Bring

• 4–7 years of full-stack product engineering experience, with non-trivial work on production systems used by real customers.
• Strong TypeScript/Node.js; comfort writing both frontend (React) and backend services.
• Hands-on GraphQL experience — ideally federation (Apollo Federation / Mercurius / similar), schema design, subgraph composition, persisted queries, performance tuning.
• Solid SQL and comfort with MySQL or Postgres in production; bonus for ClickHouse or Redis experience.
• Familiarity with AWS (EKS, Lambda, Aurora) and containerised deployment on Kubernetes.
• Comfortable with modern observability, feature flags, and CI/CD pipelines.
• Care for developer experience — APIs you would want to consume, docs you would want to read, errors you would want to debug.
• Bonus: experience with billing/commerce systems (Stripe / PayPal), API gateways, rate-limiting, agent protocols (MCP, A2A, x402), or LLM-based developer tooling.
• You are pragmatic, ship-oriented, and comfortable in a system big enough that no one person knows all of it.
