Prompt Engineer: what this role brings to your project
A prompt engineer turns prompts into a product artefact: designing the system prompts that set the model's behaviour, writing few-shot examples that anchor the answer, versioning every change like code and evaluating the result before production.
They are not the person who "writes well for ChatGPT": they guarantee the model behaves the same tomorrow as today, with prompt injection defences included.

Why work with Shakers
The advantages of adding this profile with Shakers
AI stops being a personal recipe
The prompts that lived in one chat become versioned system prompts: the same results for the whole team, with an owner.
Every change evaluated before shipping
An evaluation battery runs before each deploy: the change that improves one case and breaks others never reaches production.
Answers anchored to your examples
Few-shot with real cases from your business: the model answers in your tone and by your criteria, not with generic filler.
Capacity without growing headcount
Prompts in production by project, no hiring process: certified talent with your access and your current model.
Defences against prompt injection
User input and external sources treated as what they are: an attack surface for the model's behaviour.
Token cost under control
Prompts measured per use case: length and model routing are decided with the bill on the table.
Frequently asked questions
Any other questions? Our team will answer them.
Tell us your data projectWhat does a prompt engineer actually do?
They turn prompts into product: system prompts that set behaviour, few-shot examples, a version per change and evaluation before shipping. From trick to system.
How much does a Prompt Engineer engagement cost?
Scope sets the price: how many use cases, how much evaluation and whether there are injection defences. The budget closes per project before starting.
Is prompt engineering still a thing?
As a systems discipline, yes: models improve, but someone has to set behaviour, evaluate it and version it. The tool changes; the judgement of whoever does it doesn't.
Prompt Engineer, AI Engineer or Context Engineer?
The prompt engineer sets the model's behaviour; the context engineer designs the data it receives; the AI Engineer integrates it into product. They cross paths on real projects.
Can prompt engineering projects be done remotely?
Almost all: the work happens over APIs and repositories, and sessions with the team are remote. Only the occasional kickoff asks for presence.
What does a prompt engineer need to start?
Access to the model or API, the use cases you already tried and one session to fix the success criteria. With that, the first prompt inventory arrives in days.
What gets delivered in the first weeks
An inventory of the prompts living in personal chats, rewritten as versioned artefacts: system prompt, examples, success criteria and an evaluation battery before every change.
971 live UK vacancies mention prompt engineer
971 live UK tech vacancies mention prompt engineer, according to Shakers' market analysis (n=39,811, September 2026), almost always inside AI Engineer titles: the trade exists as a skill. The role searches 4,400 times a month and the first page is all guides.
What this role is not
Not a bag of tricks: if your problem is what data the model receives, the role is context engineer; if it's integrating it, AI Engineer. This one sets behaviour.
The prompt is code
Versioned, reviewed, evaluated and tested against injection. The difference between a pilot that charms and a system that holds is that discipline.

Find specialists in Tech, Product, Data to complement your team
AI Engineer
Integrates the model into your product: the APIs and application layer that consume the prompts your specialist designs.
AI Agent Developer
When prompts move inside agents with tools and memory: the person who orchestrates the whole conversation.
Context Engineer
Designs the data reaching the model's window: RAG, memory and curation. Behaviour is the prompt's; context is theirs.
Python Expert
The scripts that automate your evaluation and deployment when the process outgrows a notebook and needs a real pipeline.
