What exactly is the objective of this role?

We're looking for an AI Fullstack Engineer - II to join Network Platforms. This role suits someone with around 4-6 years of relevant experience who can own features end to end, from the user interface to the services and data layers behind it, and who uses AI tools thoughtfully to build faster without compromising quality.

What will be my Key Responsibilities?

• Design and build intuitive, accessible, and responsive user interfaces using modern JavaScript frameworks such as React, Angular, or Vue.js, with strong command of HTML, CSS, and JavaScript. In React, apply core patterns such as hooks (useState, useEffect) and conditional rendering.
• Optimize front-end and back-end applications for speed, scalability, and a seamless experience across devices, using performance profiling and measurement to guide your decisions.
• Develop robust APIs, services, and server-side logic in Java with Spring Boot, applying sound OOP principles and core Java features such as collections and streams, and designing for concurrency, scalability, and high availability.
• Design, implement, and maintain RESTful or GraphQL APIs, with attention to clear contracts, versioning, security, and observability.
• Design and manage relational (PostgreSQL, MySQL) and NoSQL (MongoDB, DynamoDB) databases, applying database design principles to model data effectively and keep queries performant.
• Deploy, manage, and monitor applications in cloud environments such as AWS, Azure, or GCP, using containerization tools like Docker and Kubernetes, and work with CI/CD pipelines to keep deployment cycles smooth and reliable. Use Git for version control and collaborative workflows.
• Use AI tools regularly in Java and front-end development, and take responsibility for the result: refine AI-generated code, review it critically, and validate it through console debugging and automated unit tests (for example, Jest).
• Own the quality of what you ship through code reviews, testing, and clear documentation. Collaborate with product managers, designers, and fellow engineers in an agile environment, communicate clearly, share knowledge, and support the growth of less experienced teammates. Solve problems with close attention to detail and thrive in a fast-paced setting.
• Qualifications: B.Tech, bachelor’s, or master’s degree in Computer Science, Engineering, or a related field, along with around 4-6 years of relevant development experience.

What will be nice to have?

• Hands-on experience with LLM APIs and AI frameworks such as LangChain, LlamaIndex, or Hugging Face, and knowledge of vector databases such as Pinecone, FAISS, Weaviate, or Milvus.
• Exposure to building RAG-based applications, chatbots, copilots, or AI agents.
• Experience deploying on AWS or GCP using Docker, Kubernetes, or serverless approaches.
• A strong focus on business outcomes and a desire to build products that users love, paired with self-motivation, the ability to communicate and defend your ideas clearly, and a habit of staying current with new technologies. You collaborate openly and comfortably across functional boundaries.

Why This Role?

• Build digital products from scratch on modern, cloud-native infrastructure.
• A real mandate to run lean and AI-first — not lip service, but how we actually operate.
• Influence at both ends — hands-on enough to matter in the detail, senior enough to shape strategy.
• A fast, agile culture where releases ship quickly and your judgment drives the roadmap.

WITH THE RIGHT TEAM, ANYTHING IS POSSIBLE.

If you're looking for an environment that's fun and friendly but incredibly fast-paced; a place where we measure the time between releases in days; a place where our focus begins and ends at the consumer, we'd love to have you!
