• Build and integrate LLM‑based solutions (OpenAI, Gemini, Anthropic) into real‑world use cases.
• Develop and maintain agentic systems, multi‑agent orchestration, task delegation, and autonomous workflows.
• Implement RAG pipelines, embeddings, and vector search to enhance AI system performance.
• Collaborate with technical leads and stakeholders to translate business needs into scalable technical solutions.
• Contribute to architecture decisions related to AI integration and application design.
• Ensure code quality, scalability, and maintainability through best practices and code reviews.
• Participate in deployment processes, CI/CD pipelines, and cloud‑based infrastructure.
• Optimize the performance of applications and AI models in production environments.
• Write clear technical documentation and share knowledge within the team.
• Stay up to date with AI and LLM advancements and propose relevant improvements.
• Implement LLM‑based features using prompt engineering, embeddings, and fine‑tuning techniques.
• Design and orchestrate agent‑based systems for complex workflows.
• Build and maintain RAG architectures using vector databases such as Pinecone and FAISS.
• Evaluate and improve AI outputs based on relevance, accuracy, and business impact.
• Contribute to reusable AI components, tools, and internal frameworks.
• Ensure responsible AI usage, including data privacy, security, and ethical considerations.
• Participate in all phases of the software development lifecycle, from ideation to deployment.
• Anticipate risks and dependencies, proactively addressing potential challenges before they arise.

Qualifications

• Bachelor’s degree in Computer Science or related field.
• 4–5 years of software engineering experience, with strong exposure to AI and LLM technologies.
• Hands‑on experience with LLM platforms such as OpenAI, Gemini, Anthropic.
• Strong understanding of prompt engineering techniques (zero‑shot, few‑shot).
• Experience with embeddings, semantic search, and RAG architectures.
• Experience with agentic frameworks and multi‑agent orchestration systems.
• Familiarity with AI frameworks and tools such as LangChain, LangGraph, MLflow.
• Understanding of LLMOps concepts including evaluation, monitoring, and iteration.
• Experience designing scalable, maintainable software architectures.
• Experience with CI/CD pipelines and DevOps best practices.
