An AI assistant for long documents, analysis and code, with Claude Code and Cowork on paid plans.
Prompt engineer
ShrinkingAs a standalone job title it shows up less and less: models understand plain requests better, and every employee is now expected to know how to give AI a task. The skill itself hasn't gone away. It moved inside other roles and grew into working with context.
Where this job sits on the map
In the same group: 8 of 100 professions.
What changes
Fewer job postings carry the title "prompt engineer", and the skill shows up in the requirements for other roles instead.
Choosing the right words matters less than assembling the context: the documents, examples, tools and rules the model receives.
A prompt's quality is tested on a set of examples, not by eye.
AI drafts, the person decides
How the work splits here: AI prepares a draft, the person checks it and makes the call.
What AI does
- Improves and rewrites a prompt from a description of the task
- Suggests prompt variants and examples to go with them
- Runs one prompt on different inputs and compares the answers
- Shortens long prompts without losing the meaning
What stays with the person
- Understanding the business problem: what counts as a good result
- The set of test examples and choosing the best version
- Knowing the field; without it a prompt comes out generic
- Responsibility for what the assistant tells customers
