L&T Junior Developer – AI Recruitment 2026 | BE/BTech | Chennai

1) Job Summary

The posting does not mention salary. Check the official page for any updates before applying.

2) Job Description

The selected candidate will help add AI and Generative AI capabilities to digital learning and platform products. According to the posting, the main responsibilities include:

• Developing and integrating AI/ML and Generative AI features into products
• Building applications with LLMs, NLP, Retrieval-Augmented Generation (RAG), embeddings, and vector databases
• Creating APIs that connect AI services with existing platform applications
• Writing clean, maintainable, and scalable code, mainly in Python
• Helping develop and optimise prompts for LLM-based applications
• Supporting data preprocessing, model evaluation, testing, and basic machine learning workflows
• Working with Product, Engineering, UI/UX, and Data teams
• Building prototypes and proofs of concept for emerging AI use cases
• Supporting deployment, debugging, and monitoring of AI applications
• Taking part in code reviews, testing, and documentation
• Keeping up with developments in Generative AI, LLMs, and AI agents

3) Eligibility Criteria

• Education: Bachelor of Technology (B.Tech)
• Experience: 1–2 years
• Core skills: Strong Python knowledge, sound programming fundamentals, and basic understanding of AI and machine learning concepts
• Applied AI exposure: Hands-on work with Generative AI or LLM-based applications, including familiarity with prompt engineering, RAG, embeddings, vector databases, NLP, and REST APIs
• Tools and frameworks: Exposure to PyTorch, TensorFlow, Scikit-learn, LangChain, or LlamaIndex
• Other requirements: Basic SQL and database knowledge, familiarity with Git/GitHub, and strong analytical and problem-solving ability

Who Should Apply?

• B.Tech graduates with one to two years of software or AI development experience
• Developers who have built LLM projects, even small ones such as a RAG-based Q&A tool or a chatbot
• Python programmers who want to move from general development into applied AI
• Candidates interested in education technology and digital learning platforms
• Those who learn quickly and follow new AI tools and techniques

Who May Not Be a Good Fit?

• Candidates without a B.Tech degree, since it is the stated minimum qualification
• Freshers with no practical coding or project experience, and those with far more than two years of experience who are targeting senior roles
• Candidates who know AI only in theory and have never built or tested anything
• People unwilling to work from Chennai or to collaborate across teams

4) What Should Be Highlighted in the Resume?

Since recruiters usually scan resumes quickly, make these points easy to find:

1. Python projects: Mention what you built, which libraries you used, and the result.
2. Generative AI work: List any LLM, RAG, or prompt engineering projects and the tools involved (for example, LangChain or LlamaIndex).
3. Frameworks: Name PyTorch, TensorFlow, or Scikit-learn only if you have actually used them.
4. API and database skills: Show experience with REST APIs, SQL, and any vector database.
5. Version control: Link your GitHub profile with clean, documented repositories.
6. Measurable outcomes: For example, “reduced response time by 30%” or “built a prototype used by 50 testers.”
7. Teamwork: Show code reviews, documentation, or work with design and data teams.

Keep the resume to one or two pages and use keywords that match the job description honestly.

5) What Candidates Should Expect During the Recruitment Process

The posting does not describe the selection stages, so what follows is a general expectation for technical roles, not a confirmed L&T process:

• Application: Register and apply through the official L&T careers portal.
• Resume screening: Your profile is checked against the required skills and experience.
• Technical evaluation: This may include Python and programming fundamentals, AI/ML concepts, and questions on your past projects.
• Interview round(s): Expect discussion of LLMs, RAG, APIs, and how you approach problems.
• HR discussion: This typically covers your background, expectations, and documents.

Revise Python basics, be ready to explain every project on your resume, and practise describing how a RAG pipeline works.
