A prompt engineer's job is to design, create, and optimize prompts for AI systems. They use a combination of technical skills, creative writing, and analytical thinking to do the following: 

• Develop prompts: Create prompts for text generation, translation, question answering, and creative writing 
• Collaborate: Work with product teams, data scientists, and engineers to understand user needs 
• Analyze data: Interpret data, evaluate prompt performance, and identify patterns 
• Troubleshoot: Investigate and correct issues and bugs that may arise in AI prompt systems 
• Communicate: Work effectively with other team members and stakeholders 

Some other skills that prompt engineers should have include: 

• Natural language processing (NLP)
• A deep understanding of NLP techniques is required to develop prompts that guide chatbots to respond to user input 
• Inference efficiency
• This skill focuses on minimizing the time and resources required for an LLM to generate output based on prompts 
• Portfolio
• A portfolio of AI prompts and how they were used to achieve valuable output can give prompt engineers an advantage in job applications
