• Ensure compliance with security, accessibility, and performance standards.
• Support production handovers and assist with incident resolution when required.

What do I need?

• Strong proficiency in React.js, JavaScript/TypeScript, and Node.js.
• Experience with API development, Swagger/OpenAPI, and microservices architecture.
• Programming skills in Python, with familiarity in ML libraries such as PyTorch, TensorFlow or scikit-learn.
• Hands-on experience with AI frameworks like LlamaIndex, LangChain, AutoGen, etc.
• Experience building CI/CD pipelines and automation using Jenkins, GitHub, and Bamboo.
• Exposure to AWS, Docker, and DevOps practices.
• Strong communication and stakeholder engagement skills.

Nice-To-Have:

• Familiarity with graph databases and their usage patterns.
• Understanding of large language model (LLM) architecture.
• Knowledge of fine-tuning techniques and Retrieval-Augmented Generation (RAG).
• Experience with Agentic AI frameworks and tools.
