Position Summary And Primary Responsibilities

Position Summary :

We are looking to hire an experienced, AI-native Full Stack Developer with strong expertise in both back-end (Java/Node) and front-end (React/Angular) technologies. The ideal candidate should have prior experience working as a senior developer and a proven track record of operating within a modern, high-velocity engineering model. In this role, you will treat AI as an extension of your cognitive stack—leveraging advanced developer environments (like Cursor and GitHub Copilot) to ship production-ready web features at unprecedented speeds.

Concurrently, you will possess the foundational systems-thinking required to act as a Product Builder, designing and embedding intelligent features (such as LLM APIs, semantic search, and RAG pipelines) directly into our core application architecture. You will coordinate with various stakeholders to ensure the ultimate quality, security, and scalability of our software systems.

Responsibilities

  • Ability to work with business stakeholders to convert loose business requirements into software systems and application requirements, utilizing AI collaboration tools to rapidly draft and iterate on BRDs and SRDs.
  • Convert SRDs into technical and application designs working with the Architect, leveraging LLMs to quickly prototype alternative patterns and benchmark system architectures.
  • Use prescribed software technology alongside cutting-edge AI development environments (Cursor, Copilot, or specialized coding agents) to build application/software systems across Front-end, Back-end, and Database systems.
  • Act as the expert human-in-the-loop and gatekeeper for AI-generated code—reviewing, refactoring, and verifying outputs to eliminate technical debt and enforce strict security guardrails (e.g., preventing payload tampering or API manipulation).
  • Design and implement intelligent application features, including Retrieval-Augmented Generation (RAG) pipelines, asynchronous LLM orchestrations, and basic vector infrastructure (e.g., PGVector, Pinecone, or LangChain/LlamaIndex).
  • 2+ years of experience implementing robust, distributed web applications, with a clear personal trajectory of scaling individual velocity over the past 12–18 months using generative AI tools.
  • Track-record of technical delivery using software development best practices (such as DRY, SOLID, and secure coding patterns).
  • Track-record of being a highly execution-focused, hands-on developer who thrives in modern, flattened engineering structures where individuals own massive functional surface areas.
  • Experience building full-stack web applications with Java/Node (Spring Boot, NestJS/Express) and React JS / Angular, Redux (MEAN/MERN stacks, Java).
  • Experience in writing and generating robust unit test cases using automated testing frameworks to ensure bulletproof code coverage during rapid AI iterations.
  • Experience with Continuous Integration and Continuous Deployment (CI/CD) practices and tools to maintain a fast, automated pipeline from code generation to production cloud environments.
  • Experience in delivering applications in a global agile delivery model, managing token/infrastructure costs, and navigating shifting product requirements seamlessly.
  • Experience in deploying and managing containerized applications using Docker & Kubernetes on Azure or any other major cloud platform.
  • Experience in React server-side rendering (SSR) using Airbnb/hypernova, or component isolation with React Storybook is a plus

Qualification : Bachelor’s degree in Engineering with 2-5 years of experience.
