The role develops, tests and optimises prompts for large language model (LLM) applications used across high voltage (HV) use cases, and works with Product Management, Engineering, Marketing, Pricing and Sales to embed AI assistants into real business processes.

Key responsibilities

• Develop, test and optimise advanced prompts for LLM-based applications in HV use cases such as 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 (CoT, ReAct, role-based prompting, agentic workflows) to ensure accuracy, consistency and context awareness.
• Partner with Product Management, Engineering, Marketing, Pricing and Sales to embed AI assistants into business processes.
• Define prompt standards, templates and best practices so they can be scaled and reused.
• Evaluate prompt performance using qualitative and quantitative metrics such as accuracy, hallucination rate, usability and business impact.
• Work with AI/ML engineers to align prompting logic with RAG pipelines, vector databases and enterprise data sources.
• Keep up to date with GenAI capabilities, LLM limitations and emerging prompting techniques, and support adoption by documenting use cases, training users and explaining AI behaviour to stakeholders.
• Ensure compliance with applicable external and internal regulations, procedures and guidelines.

Required profile

• Bachelor's degree in Engineering.
• Minimum 5 years of professional experience in AI / Data / Software Engineering with strong applied GenAI exposure, or in Product Management or Engineering in High Voltage or Power Systems with demonstrated AI adoption.
• Prior exposure to industrial, infrastructure or engineering-driven environments is strongly preferred.
• Proven ability to work cross-functionally with engineering, product, sales, pricing and IT teams.
• Professional proficiency in English.

Required skills

• Hands-on experience with GenAI platforms such as Azure OpenAI, OpenAI APIs, LangChain, AutoGen or similar frameworks.
• Strong understanding of High Voltage equipment and solutions, including GIS and AIS technologies, their components, configurations, customer applications and grid use cases (TSOs, utilities, industry), as well as relevant standards, lifecycle phases and customer decision drivers.
