Key Responsibilities

• Design and implement AI solutions using agents, LLMs, planning algorithms, and decision-making frameworks
• Develop agent based architectures that support autonomy, interactivity, and task completion
• Implement best practices for orchestration and observability, monitor performance, conduct evaluations, and implement safety and guardrail mechanisms
• Integrate agents into applications, APIs, or workflows (e.g., chatbots, copilots, automation tools)
• Collaborate with researchers, engineers, and product teams to iterate on AI capabilities
• Optimize AI behaviour and results through feedback loops, reinforcement learning, or user interaction
• Maintain thorough documentation of logic, design decisions, and dependencies

Requirements

• BSc or MSc in Computer Science, AI/Machine Learning, CyberSecurity, or a related field
• 3+ years of experience building enterprise software applications
• Strong programming skills in Python (or similar) and experience with AI/ML libraries (e.g., LangChain, OpenAI API, Hugging Face, PyTorch)
• Knowledge of application security principles and best practices
• Understanding of agent-based modeling, multi-agent systems, or reinforcement learning
• Experience building applications with LLMs or generative AI models
