Job Description

Responsibilities

  • Lead the design, development, and deployment of scalable AI-powered applications using Python, Large Language Models (LLMs), Agentic AI frameworks, and Cloud Technologies.
  • Design and implement multi-agent systems, including agent orchestration, reasoning, planning loops, memory management, and workflow automation.
  • Drive the technical roadmap for Generative AI and Agentic AI initiatives, ensuring alignment with business objectives and enterprise architecture standards.
  • Provide technical leadership and hands-on guidance to development teams across the full Software Development Life Cycle (SDLC).
  • Design and build highly available, secure, and low-latency cloud-native applications leveraging Azure and modern cloud services.
  • Collaborate with Product Owners, Business Analysts, Architects, and cross-functional teams to translate business requirements into scalable technical solutions.
  • Lead API architecture, integration, and optimization efforts using FastAPI, RESTful services, and event-driven architectures.
  • Establish engineering best practices, including code reviews, CI/CD pipelines, automated testing, DevSecOps, and quality governance.
  • Drive performance optimization, observability, reliability, scalability, and operational excellence across AI platforms and services.
  • Collaborate with stakeholders to identify, prioritize, and deliver high-impact AI use cases and transformation initiatives.
