How You’ll Make An Impact

Develop, test, and optimize advanced prompts for LLM-based applications across HV use cases (e.g. product configuration, technical documentation, RFQ support, pricing logic explanation, customer proposals, and engineering knowledge retrieval). Translate complex High Voltage product knowledge (GIS, AIS, major components, lifecycle, standards, and applications) into structured prompts, guardrails, and AI workflows. Design multi-step prompting strategies (e.g. CoT, ReAct, role-based prompting, agentic workflows) to ensure accuracy, consistency, and context awareness. Partner closely with Product Management, Engineering, Marketing, Pricing, and Sales to embed AI assistants into real business processes. Define prompt standards, templates, and best practices to enable scale and reuse across the organization. Continuously evaluate prompt performance using qualitative and quantitative metrics (accuracy, hallucination rate, usability, business impact). Work with AI/ML engineers to align prompting logic with RAG pipelines, vector databases, and enterprise data sources. Act as a bridge between AI technology and HV product reality—ensuring AI outputs are technically correct, commercially relevant, and compliant with internal standards. Maintain up-to-date knowledge of GenAI capabilities, LLM limitations, and emerging prompting techniques, and assess applicability to HV use cases. Support change management and adoption by documenting use cases, training users, and explaining AI behavior transparently to business stakeholders.
