JOB SUMMARY:
We are seeking an experienced Senior Generative AI / Platform Engineer to lead the architecture, development, and scaling of our clients next-generation AI orchestration platform. In this role, you will bridge the gap between cutting-edge AI research and robust enterprise infrastructure.

This resource will be responsible for designing advanced Retrieval-Augmented Generation (RAG) pipelines, building resilient AI Agents, implementing cutting-edge interoperability protocols like MCP, and pioneering multi-agent (Agent-to-Agent) collaboration networks.

The ideal candidate possesses deep expertise in Python for AI/LLM orchestration, a strong backend foundation in Java (Spring Boot), and proven experience deploying and managing containerized workloads across a hybrid-cloud topology consisting of on-premises Red Hat OpenShift and Amazon Web Services (AWS).

Core Responsibilities:

• Hybrid Cloud Infrastructure & Deployment: Architect, deploy, and scale GenAI services, vector databases, and model gateways across a hybrid environment utilizing on-premises Red Hat OpenShift and public cloud services in AWS (e.g., EKS, Bedrock, EC2).
• Advanced RAG & Retrieval Optimization: Design and optimize enterprise RAG pipelines.
• Implement advanced retrieval strategies, including hybrid search (vector + lexical) and high-precision reranking workflows (using cross-encoders) to minimize LLM context noise, optimize token usage, and eliminate hallucinations.
• Agentic Systems & Tool Orchestration: Build, deploy, and monitor production-grade AI Agents capable of autonomous planning, tool usage, complex multi-step reasoning, and self-correction.
• Context Integration & Interoperability: Architect scalable integrations between LLMs and enterprise data silos using the Model Context Protocol (MCP), establishing clean, standardized interfaces for tool servers and data sources.
• Multi-Agent Networks (A2A): Design and implement Agent-to-Agent (A2A) collaboration systems, enabling specialized, decoupled agents to communicate, delegate tasks, and negotiate state synchronously or asynchronously.
• Enterprise Integration & Backend Development: Build secure, high-throughput, and fault-tolerant microservices in Java/Spring Boot to serve GenAI features, manage data orchestration, and expose robust endpoints.

Required Technical Experience

• Hybrid Cloud & Container Orchestration: Red Hat OpenShift: Deep hands-on experience deploying, managing, and troubleshooting containerized enterprise applications in an on-premises OpenShift environment (including managing security contexts, routes, and cluster resources).
• AWS Platform: Strong expertise with core AWS infrastructure and AI/ML services (e.g., IAM, VPC, Amazon Bedrock, EKS, RDS). Dual-Stack Mastery (Python & Java): Python: Expert-level proficiency for AI/ML tasks, asynchronous programming, and data engineering. Java: Deep experience building distributed microservices utilizing the Spring Boot ecosystem (Spring Web, Spring Security, Spring Data).
• Generative AI Frameworks: Practical experience with orchestrating frameworks such as LangChain, LlamaIndex, LangGraph, AutoGen, CrewAI, LangChain4j, or Spring AI.
• Advanced RAG Stack: Experience with vector databases (e.g., Pinecone, Qdrant, Milvus, pgvector) alongside dedicated reranking APIs (such as Cohere Rerank, BGE, or open-source cross-encoders).
• Protocols & Standards: Solid understanding of MCP (Model Context Protocol) or experience building universal API layer abstractions for LLM tool utilization. MLOps, DevSecOps & Observability: Familiarity with LLM evaluation frameworks, CI/CD pipelines targeting OpenShift/AWS, and enterprise observability tools (e.g., Prometheus, Grafana, OpenTelemetry, LangSmith).

Preferred Qualifications

• Experience configuring on-prem OpenShift clusters with GPU acceleration (NVIDIA GPU Operator) for local LLM or embedding model hosting.
• Relevant certifications such as Red Hat Certified Specialist in OpenShift or AWS Certified Solutions Architect / Machine Learning Specialty.
• Active contribution to open-source GenAI projects, MCP servers, or multi-agent ecosystem tools.

Required Work Experience:
5+ years related work experience, Professional experience with technical design and coding in the IT industry

Required Education:
Related Bachelors degree or additional, related work experience
