If you want your work to matter, we're the right organisation for you.

We’re looking for a detail-oriented and creative Prompt Engineer / Junior Data Scientist to join our growing team. In this role, you will design and refine prompts for summarisation tasks using large language models (LLMs). You'll contribute to building effective NLP pipelines, analysing model outputs, and presenting insights that drive product and research decisions. 

Key Responsibilities

• Iterate on prompt engineering based on qualitative feedback to improve the quality, clarity, and relevance of outputs. 
• Collaborate with developers to define evaluation criteria for summarisation outputs.
• Create clear, informative data visualisations to communicate technical insights to both technical and non-technical stakeholders. 
• Communicate your findings with technical and non-technical staff and clients. 
• Familiar with agile processes such as sprint planning, review, and retrospectives and experience working in cross-functional teams. 
• Support client communication by translating vague or ambiguous needs into structured, effective prompts.

• Basic understanding of natural language processing (NLP) concepts and large language model (LLM) behaviour.
• Familiarity with prompt engineering principles and how prompt design impacts LLM output quality.
• Strong analytical and problem-solving skills, with an ability to present complex information clearly.
• Exceptional written English and a strong grasp of grammar, tone, and nuance.

Who You Are

• You’re curious and thoughtful, with a desire to understand how humans and machines communicate.
• You care about detail—whether that’s in a chart, a model output, or a sentence.
• You enjoy working in a fast-paced, collaborative environment where you can learn and make a meaningful impact.
