• Experiment rapidly with new AI capabilities, taking ideas from proof of concept through validation and scalable adoption.
• Design effective context, orchestration and verification mechanisms for reliable agentic workflows.
• Measure how agents are used and the value they create, using data and feedback to continuously improve them.
• Make thoughtful decisions about where AI can add value, where human judgment remains essential, and how the two should work together.
• Collaborate closely with engineers, designers, product, and data teams across Preply to understand their workflows, drive adoption and identify new opportunities for automation.
