Job Summary

Demand Unit Name  :  Generative AI Engineer II - LLM Application Engineering
Band : E2.1 
Target : Engineering Graduates from  Tier 1 Institutions (IIT, NIT, DTU)
Purpose of the Role: 
The Platform Engineer II will design, build, and optimize scalable platforms that support Large Language Model (LLM) application development, deployment, and operations. This role enables rapid experimentation and reliable productionization of Generative AI solutions by creating robust infrastructure, automation pipelines, and integration frameworks. The engineer collaborates closely with AI/ML, application development, and DevOps teams to ensure high system reliability, security, and performance across the LLM lifecycle.

Key Responsibilities

Responsibilities :

1. Architect, implement, and enhance platform components supporting LLM-based application engineering, including model serving, vector databases, feature stores, and data pipelines.
2. Develop and maintain CI/CD automation for model deployment, evaluation, monitoring, and rollback.
3. Optimize infrastructure for performance, scalability, cost efficiency, and enterprise-grade security.
4. Integrate LLM services with internal tools, APIs, microservices, and cloud-native systems.
5. Build observability frameworks including logging, tracing, model performance metrics, and guardrail monitoring.
6. Support fine-tuning and RAG (Retrieval-Augmented Generation) workflows by enabling scalable data processing and model hosting.
7. Troubleshoot production issues, conduct root-cause analysis, and drive continuous platform improvements.
8. Collaborate with cross-functional teams to establish best practices, governance, and reusable components for LLM application delivery.
9. Contribute to documentation, knowledge sharing, and internal enablement around platform architecture and usage.
10. Work with stakeholders to identify key business problems and determine how AI can address them
11. Stay up-to-date with the latest AI trends and technologies, Responsible AI to continually enhance your skills and contributions.
