You will also evaluate these systems for accuracy, reliability, safety and effective grounding. 

Your key responsibilities:

• Design and build generative artificial intelligence applications using proprietary and open-weight large language models. 

• Develop agent-based systems and workflows that support planning, memory, tool use, orchestration, human oversight and autonomous tasks. 

• Integrate artificial intelligence solutions with enterprise platforms, application programming interfaces and business workflows. 

• Build and deploy representational state transfer services using Flask or FastAPI. 

• Evaluate model, agent and system performance, including accuracy, reliability, grounding and safety. 

What you bring:

Required qualifications: 

• At least 10 years of overall professional experience, including at least 4 years working with artificial intelligence, generative artificial intelligence or agent-based artificial intelligence. 
• Designing and building GenAI-powered applications using LLMs (open & proprietary)

• Building agent-based systems with planning, memory, tool use, and orchestration
• Implementing Agentic workflows (multi-agent, human-in-the-loop, autonomous tasks)

• Hands-on experience with large language models, prompting techniques, structured outputs, model routing, context management, memory management and retrieval-augmented generation. 

• Strong proficiency in Python and experience with machine learning frameworks and libraries such as scikit-learn, TensorFlow, PyTorch, Keras or pandas. 

• Experience with vector databases, retrieval systems, cloud platforms such as Amazon Web Services, Google Cloud or Microsoft Azure, and services built with Flask or FastAPI. 

• Bachelor's degree in engineering or a related field, or an equivalent combination of education, training and work experience. 

Preferred qualifications: 

• Experience fine-tuning large language models, including parameter-efficient approaches such as low-rank adaptation and quantized low-rank adaptation. 

• Familiarity with orchestration tools such as LangChain, LlamaIndex, AutoGen or the OpenAI Assistants application programming interface. 

• Knowledge of production machine learning operations, continuous integration and delivery, monitoring, observability, security, compliance and data governance.
