Prompt Engineer / LLM Engineer

You obsess over the exact instructions we give to models — and the data we retrieve for them, and the evaluations we grade them with. You know when to prompt, when to fine-tune, and when to redesign the workflow.

What you’ll build

• Production prompts and agent loops across multiple product lines.
• Evaluation datasets that quantify quality per feature.
• Structured-output pipelines with reliable schema conformance.
• Automation to detect regressions on every prompt change.

Requirements

• 3+ years software engineering.
• Deep intuition for what LLMs can and can’t do — earned in production.
• Fluent in Python or TypeScript.
• Rigorous about eval, not just vibes.
• Right to work in the UK.
