Responsibilities

Agentic AI Architecture & Systems Design

• Design and operationalize agentic AI systems within an enterprise IT and Service-Oriented Architecture (SOA) framework.
• Define system components, APIs, and interfaces for embedding agent-based intelligence into scalable, modular platforms.
• Ensure adaptability, reusability, and maintainability of agentic AI services across enterprise applications.

AI Workflow & Business Integration

• Collaborate with business and IT stakeholders to align agentic AI capabilities with strategic goals and operational workflows.
• Translate business requirements into intelligent agent-driven processes that optimize decision-making and automation.
• Conduct feasibility assessments and define KPIs for agent-enabled systems.

Data & Model Infrastructure

• Architect and manage the infrastructure supporting agentic AI workflows, including real-time data pipelines, feature stores, and model registries.
• Oversee the full lifecycle of AI agents—from model training and orchestration to deployment, monitoring, and iteration.
• Seamlessly integrate ML models, reasoning engines, and multi-agent systems into core IT and product platforms.

Scalability, Performance & Optimization

• Design systems to support distributed, high-performance, and real-time agentic AI processing.
• Optimize infrastructure for low-latency decision loops and efficient agent coordination.
• Balance performance, cost, and scalability across AI compute resources and workflows.

Collaboration & Leadership

• Partner with data engineers, software developers, MLOps, and DevOps teams to ensure robust integration and lifecycle management of intelligent agents.
• Define and enforce best practices for agent orchestration, CI/CD of AI systems, and live system monitoring.
• Provide strategic and technical leadership in the operational deployment of AI agents across the enterprise.

Requirements

Experience

• 8+ years in AI systems architecture, data science, or enterprise software engineering.
• Proven experience implementing AI/ML systems within SOA or cloud-native architectures.
• Hands-on experience integrating autonomous AI agents or models into enterprise products.

Technical Skills

• Proficiency with AI/ML frameworks (e.g., PyTorch, TensorFlow, Scikit-learn) and agentic system design.
• Advanced Python development skills; experience with deployment tools and container orchestration (e.g., Docker, Kubernetes).
• Deep knowledge of data pipelines, event-driven architectures (Kafka, Flink), and real-time AI processing.
• Experience with MLOps, model versioning, and observability tools in production environments.

Strategic & Analytical Thinking

• Ability to align agentic AI capabilities with business priorities and technical constraints.
• Skilled in conducting impact assessments, risk analyses, and designing AI-first processes.
• Strong problem-solving and communication skills across technical and non-technical audiences.

Preferred Qualifications

• Certifications in AI, Machine Learning, or Agent-Based Systems
