Director of AI Systems & Foundation Models
What this person actually does
-
Leads a high-calibre team of AI scientists and ML engineers building large-scale, production-ready AI systems
-
Designs and delivers foundation models using self-supervised and representation learning techniques
-
Builds models that learn across multiple data modalities and scales, from granular signals through to population-level insights
-
Embeds explainability, uncertainty and causal reasoning into model design, not as an afterthought
-
Partners closely with downstream teams to ensure models can be fine-tuned, deployed and deliver real-world impact
-
Makes clear, defensible build vs adapt vs buy decisions across models, tooling and external partnerships
-
Sets standards for model evaluation, bench-marking, validation and data quality
-
Represents the organisation externally through publications, open-source contribution or recognised thought leadership
What success looks like
-
Reusable AI systems that are actively leveraged across multiple high-value applications
-
Models that improve as new data modalities are introduced
-
Clear translation from research into deployed capability
-
Strong internal confidence in model outputs due to explainability and uncertainty awareness
-
A motivated, high-performing team with strong retention and progression
The kind of background that fits
-
Deep expertise in modern machine learning, especially foundation models, self-supervised learning or representation learning
-
Strong understanding of neural network architectures, multi-modal learning and transfer learning
-
Experience with distributed training, large-scale model optimisation and efficient fine-tuning
-
Proven track record of research impact (top-tier publications, widely adopted systems or equivalent)
-
Comfortable working with imperfect, real-world data rather than curated academic data sets
-
Experience translating advanced research into production-grade systems
-
Senior leadership experience, including leading leaders, hiring at scale and owning capability road maps
-
Confident communicator who can bridge technical depth and strategic clarity with senior stakeholders
Mindset and style
-
Comfortable with ambiguity and research uncertainty
-
Commercially and impact-oriented, not research-for-research's-sake
-
Curious, rigorous and opinionated, but open to challenge
-
Sets a high bar for quality, documentation and reproducibility
-
Motivated by building things that matter, not just publishing them
Why this role is compelling
This is a rare opportunity to operate at the intersection of cutting-edge AI and meaningful real-world application, with the scope to define how advanced machine learning systems are designed, evaluated and used at scale.
