We’re working with a leading global agency supporting a major financial services client on an innovative AI initiative.

Build models that simulate campaign performance using historical data (backtesting)

Project Focus:

Objective: Predict the success of marketing content (images, videos, and text) before campaigns go live using multi-modal AI models.
Method:

Apply customer research (survey/NLP data) alongside computer vision and text models.
Build models that can take a new creative (image, video, or ad copy) and predict its expected performance.

Provide detailed post-campaign insights, including content attributes that worked (or didn’t) for different audience segments (e.g., high spenders).

Backtesting:

Models should also score new content (ads/videos/copy) before it is launched.

Ability to work with images, video, and text data simultaneously.
Experience building or applying multi-modal models (e.g., combining visual and textual inputs).

2. Experience with Open-Source Models

Ideally familiar with OpenAI CLIP or similar vision-language models.
Should know how to adapt and apply open-source AI models to real-world data (not just academic familiarity).

3. Computer Vision and NLP Skills

Computer vision: Practical knowledge – but not traditional CV (e.g., object detection) – focus is on newer multimodal models.
NLP: Able to process and leverage customer research data (e.g., surveys, text responses).

4. Programming and Statistical Foundation

Strong coding skills – must be a programmer at heart, not just a “tool user.”
Solid background in statistics and mathematics to build reliable, explainable models.
Should understand model evaluation, backtesting, and simulation of campaign performance.

5. Content Performance Modeling

Build models that:

Predict creative success for new ads, videos, and text.
Backtest models using historical data.
Score and provide insights into what aspects of content perform best.

Contract – Multi-Modal AI Specialist (OpenAI CLIP) | Up to £650/day | Outside IR35 | Hybrid/Remote

We’re working with a leading global agency supporting a major financial services client on an innovative AI initiative. The project aims to predict the performance of creative campaigns before they go live, replacing traditional A/B testing with pre-launch modelling that leverages multi-modal data (images, video, and text) and customer research.

This is a hands-on contract role for a technically strong machine learning specialist with experience applying OpenAI CLIP. Using historical data, you’ll use open-source models to assess campaign creative and help deliver insights at both content and audience levels.

Key responsibilities:

Apply OpenAI CLIP or similar models to campaign imagery, video content, and customer research (e.g., surveys)
Build models that simulate campaign performance using historical data (backtesting)
Pre-test creative content, score ad copy, and identify attributes driving success
Work with customer data (NLP) and translate insights into model features
Deliver post-campaign breakdowns by audience segment (e.g., high-value customers)

Must-have technical skills:

Proven experience with OpenAI CLIP (essential)
Strong track record with multi-modal AI (image, video, text)
Solid Python programming skills
Deep understanding of statistics and model evaluation
Comfortable working with NLP and customer research data

Contract details:

Day rate: Up to £650/day
Outside IR35
Initial office-based onboarding (1 week), then mostly remote
3-month contract with potential to extend
Fast interview process: 30-min intro + 1-hour technical

AI Engineer/ Machine Learning Engineer

London

£400 - £650

+ Computer Vision

Contract
London

To Apply for this Job Click Here

Project Focus:

Objective: Predict the success of marketing content (images, videos, and text) before campaigns go live using multi-modal AI models.
Method:

Apply customer research (survey/NLP data) alongside computer vision and text models.
Build models that can take a new creative (image, video, or ad copy) and predict its expected performance.
Reduce reliance on traditional lengthy A/B testing by using pre-testing AI models.
Provide detailed post-campaign insights, including content attributes that worked (or didn’t) for different audience segments (e.g., high spenders).

Backtesting:

AI models should be able to simulate performance against historical data to validate predictions.
Models should also score new content (ads/videos/copy) before it is launched.

Key Technical Requirements:
1. Multi-Modal AI Expertise

Ability to work with images, video, and text data simultaneously.
Experience building or applying multi-modal models (e.g., combining visual and textual inputs).

2. Experience with Open-Source Models

Ideally familiar with OpenAI CLIP or similar vision-language models.
Should know how to adapt and apply open-source AI models to real-world data (not just academic familiarity).

3. Computer Vision and NLP Skills

Computer vision: Practical knowledge – but not traditional CV (e.g., object detection) – focus is on newer multimodal models.
NLP: Able to process and leverage customer research data (e.g., surveys, text responses).

4. Programming and Statistical Foundation

Strong coding skills – must be a programmer at heart, not just a “tool user.”
Solid background in statistics and mathematics to build reliable, explainable models.
Should understand model evaluation, backtesting, and simulation of campaign performance.

5. Content Performance Modeling

Build models that:

Predict creative success for new ads, videos, and text.
Backtest models using historical data.
Score and provide insights into what aspects of content perform best.
