Prompt Engineer

As our Prompt Engineer

Your typical day with us will involve leading the development of user-facing conversational AI features, designing and testing reusable prompts as part of a broader system, and ensuring our AI applications are optimized for efficient, natural, and personalized conversational experiences in English and Japanese. You will collaborate closely with cross-functional teams to deliver scalable and flexible experiences, all while mentoring members of non-technical staff on prompt engineering best practices and contributing to the overall technical direction of the prompt engineering team.

Your Typical Day With Us:

• Design, develop, and implement a series of dynamic prompts for our conversational AI applications, ensuring high performance, scalability, and user engagement.
• Contribute to and expand the design of a system of reusable, flexible prompts that prioritize scale and personalization across myriad tenants, industries, and modalities.
• Conduct recurring tests of prompt performance prior to implementation to properly set business expectations for quality, security, and cost by model, model provider, tenant, and industry.
• Participate in on-call monitoring of AI feature performance and remedy any issues that arise due to technical difficulties.
• Educate non-technical members of the organization on prompt engineering foundational concepts, best practices, and tool usage.
• Ensure the technical feasibility of feature requests from non-technical staff, collaborating closely with the business and product teams to deliver compelling and natural conversational user experiences.
• Gather feedback on product performance, user experience, language experience, and quality from technical and non-technical staff alike, and cleanly organize data into quickly digestible reports for executive management.
• Optimize prompt performance to ensure fast output times, API calls, and overall application responsiveness.
• Collaborate with backend engineers to define API requirements, ensuring seamless integration between prompts, third party model providers, and backend systems.
• Integrate closely with product leadership to shape the vision and roadmap for AI product functionality according to business needs and cutting-edge developments in generative AI.
• Stay updated with the latest trends and technologies in prompt engineering, prompt defense, and generative AI development, continuously improving the team's skill set and technical direction.
• Participate in cross-functional meetings to align prompt engineering with product goals, business targets, and company objectives.
