This role is ideal for a hands-on AI professional with both technical expertise and domain sensitivity—capable of shaping intelligent, adaptive agents that perform reliably in complex, real-world environments. 

Responsibilities 

• Train and configure agentic AI systems to operate effectively within specialized domains, ensuring alignment with domain-specific goals, constraints, and terminology. 
• Customize agent workflows, toolchains, and decision logic to reflect domain context, operational requirements, and user expectations. 
• Adapt reasoning, planning, and state management components for accuracy and relevance in industry-specific applications. 
• Collaborate with domain experts to capture knowledge, define task flows, and validate agent behavior in representative environments. 
• Fine-tune models and configure tool integrations to support effective interaction, tool use, and decision-making in real-world scenarios. 
• Monitor agent performance, identify misalignments with domain expectations, and iteratively improve workflows and configurations. 
• Support evaluation, simulation, and continuous learning pipelines to refine agent behavior based on feedback and performance data. 
• Document domain-specific configurations, training protocols, and best practices for scalable deployment across similar use cases. 

Requirements 

Experience 

• 5+ years in AI system training, workflow configuration, or intelligent system customization, with a focus on domain adaptation. 
• Experience working with AI/ML tools in applied settings such as healthcare, finance, logistics, manufacturing, or defense. 

Technical Skills 

• Strong proficiency in Python and experience with AI/ML frameworks (e.g., PyTorch, TensorFlow). 
• Familiarity with agentic AI workflows, including planning, tool use, and multi-step task execution. 
• Hands-on experience configuring AI tools, models, and pipelines for use in constrained or specialized environments. 
• Ability to interpret domain-specific requirements and translate them into actionable agent behaviors. 

Preferred Knowledge 

• Exposure to multi-agent systems, LLM orchestration frameworks (e.g., LangChain, Autogen), or intelligent automation platforms. 
• Experience working with structured knowledge bases, ontologies, or knowledge graph integrations. 
• Familiarity with simulation environments or digital twins for domain-specific AI testing and training.
