Build evaluation frameworks and feedback loops to measure AI output quality, catch regressions, and drive continuous improvement
Implement robust guardrails, content filtering, and safety mechanisms for production AI systems
Collaborate closely with product managers, designers, and domain experts to translate user problems into well-scoped AI solutions
