Job Description
As a Prompt Engineer within the Data Science team, you will design, test and optimise prompts for large language models so that AI-driven applications return accurate, efficient and usable outputs. The role sits at the intersection of engineering and applied AI: you will translate human intent into reliable model behaviour, debug poor outputs, and continuously refine prompt strategies as generative and agentic AI tooling evolves. You will collaborate closely with product, engineering and data teams to embed these prompt strategies into real workflows and applications used by NEC’s global clients.
Key Responsibilities
- Design, develop and refine prompts for AI/LLM applications to ensure high-quality, contextually accurate outputs.
- Collaborate with product, engineering and data teams to integrate prompt strategies into applications and workflows.
- Conduct A/B testing and evaluate prompt effectiveness across different scenarios and use cases.
- Maintain a knowledge base of reusable prompt templates and frameworks for the wider team.
- Stay current with advances in generative AI, agentic AI, prompt-engineering techniques and tooling.
- Analyse model outputs, debug issues and propose prompt modifications for continuous improvement.
- Document prompt design decisions to support repeatability and knowledge sharing.
Eligibility Criteria
You Must Have
- A strong understanding of large language models such as GPT, Claude, LLaMA or similar.
- Experience with prompt design, prompt chaining and optimisation.
- Proficiency in at least one programming language, with Python preferred.
- Strong analytical and problem-solving skills.
- Excellent written and verbal communication skills.
- The ability to work in cross-functional teams and translate business needs into AI solutions.
Preferred
- Working knowledge of agentic frameworks, specifically LangChain and LangGraph.
- Prior experience working with UK clients and teams.
- Familiarity with the onshore–offshore delivery model.
- Commercial awareness in areas such as revenue recognition and margin management.
