Career Family: AIA – AGENTIC AI ENGINEER 

The opportunity

We are seeking a dynamic Senior Consultant to join our AI & Data Consulting team, focused on building enterprise-grade GenAI and Agentic AI solutions with strong emphasis on LLM engineering, frontend experience layer, reusable UI components, and real-time copilot interfaces.

The ideal candidate will bring a strong combination of AI engineering, LLM application development, agentic AI system design, backend engineering, and modern frontend development expertise. This role requires hands-on experience in building chatbots, copilots, agent-driven workflows, reusable UI SDKs, streaming interfaces, and API-driven AI experiences that are scalable, secure, maintainable, and production-ready.

You will work closely with AI engineers, backend engineers, UX designers, product owners, security teams, platform teams, and business stakeholders to design and implement LLM-powered applications, agentic workflows, Retrieval-Augmented Generation (RAG) pipelines, streaming AI interfaces, and reusable experience-layer components that accelerate enterprise AI adoption and business transformation.

Your key responsibilities

Technical Excellence:

• AI Engineering & Agentic AI Development
• Design and develop enterprise-grade GenAI and Agentic AI applications using LLM frameworks such as LangChain, LangGraph / AutoGen / Google Agent SDK, and Model Context Protocol (MCP).
• Build agentic AI architectures including multi-agent workflows, tool/function calling, enterprise integrations, memory patterns, and autonomous decision flows.
• Develop and maintain Retrieval-Augmented Generation (RAG) pipelines including document ingestion, chunking, embeddings generation, vector indexing, retrieval optimization, and response grounding.
• Implement semantic search and knowledge retrieval solutions using vector databases and hybrid search patterns.
• Develop prompt engineering strategies, tool-based agents, AI workflows, and enterprise copilots aligned to business use cases.
• Contribute to AI evaluation, observability, monitoring, and performance optimization of LLM-powered applications.
• Stay current with emerging trends in GenAI, Agentic AI, LLM frameworks, AI SDKs, multimodal AI, and enterprise AI engineering practices.

• Frontend & Experience Layer Engineering
• • Design and build modern AI user experiences using React, TypeScript, Next.js, reusable UI component libraries, and frontend SDKs.
  • Develop chatbot, copilot, and agent-driven interfaces that provide intuitive, responsive, and accessible user experiences.
  • Build reusable React and TypeScript components and SDKs that can be consumed across multiple applications and teams.
  • Implement state management, client-side performance optimization, accessibility standards, and design system integration for enterprise-grade AI applications.
  • Develop API-first and contract-driven UI integrations with backend services, agent APIs, and streaming endpoints.
  • Implement extensible plug-in patterns, schema-driven forms, typed API clients, and component-driven architectures for scalable AI experiences.

• Streaming & Real-time UI Development
• • Implement real-time AI interfaces using WebSocket’s, Server-Sent Events (SSE), and token-level LLM response streaming.
  • Build streaming chat, copilot, and agent interfaces with incremental rendering, backpressure handling, and low-latency response patterns.
  • Develop real-time visualization of agent state, workflow progress, tool usage, and execution traces.
  • Optimize streaming performance across frontend, backend, and LLM service layers.
  • Ensure safe rendering of model output, including UI-level guardrails, content handling, and secure display patterns.

• Backend & Platform Engineering
• Design and build scalable backend services using Python, FastAPI, REST APIs, microservices, and event-driven architectures.
• Develop reusable AI platform components, services, APIs, and integrations to accelerate enterprise AI adoption.
• Integrate AI solutions with enterprise systems, third-party applications, workflow platforms, and data services.
• Troubleshoot and optimize AI pipelines, APIs, vector stores, backend services, and cloud-native applications.
• Implement scalable deployment strategies using containerized and cloud-native architectures.

• Cloud, Infrastructure & DevOps
• • Deploy and manage AI applications using Docker, Kubernetes, OpenShift, and cloud-native deployment patterns.
  • Build and maintain CI/CD pipelines using GitHub Actions, GitLab CI, and modern DevOps tooling.
  • Ensure production readiness through monitoring, observability, automated testing, release management, and operational excellence.
  • Support deployment and lifecycle management across development, testing, staging, and production environments.
  • Apply scalable deployment patterns for AI services, frontend applications, reusable SDKs, and backend platforms.

• AI Governance, Security & Responsible AI
• • Implement controls for PII protection, data privacy, AI security, compliance, and responsible AI practices.
  • Support AI governance through monitoring, observability, auditability, access controls, and policy-aligned implementation.
  • Apply guardrails for prompt injection mitigation, safe tool execution, secure API access, and safe rendering of model output in UI experiences.
  • Contribute to AI observability practices including monitoring model behavior, hallucination risks, agent trajectories, retrieval quality, latency, accuracy, and user experience performance.
  • Ensure adherence to enterprise architecture, information security, accessibility, responsible AI, and engineering standards.

• Team Collaboration & Delivery Excellence 
• Collaborate with AI engineers, backend engineers, UX designers, product owners, security teams, platform teams, and business stakeholders to refine requirements and deliver scalable AI solutions.
• Participate in architecture reviews, code reviews, UX reviews, testing reviews, and technical design discussions.
