This is a rare opportunity to join a fast‑scaling AI business that’s already delivering tangible commercial impact — from billions of behavioural data points to measurable ROI.

The Opportunity

This role sits at the intersection of AI, data science, and consulting.

You’ll work directly with major enterprise clients, helping them apply advanced analytics and AI models to real-world business challenges — from customer insight to personalisation and growth.

Ideal for:

• Data Scientists looking to move into a more strategic, client‑facing role, or
• Technical Consultants wanting to go deeper into applied AI and data science.

Expect a balance of hands‑on technical delivery (≈50%) and consultative problem‑solving (≈50%).

What You’ll Be Doing

• Designing and delivering AI/ML‑driven solutions that unlock value from large‑scale behavioural data
• Building features, models and proofs‑of‑concept that help clients truly understand their customers
• Translating complex technical concepts into clear, commercial insights for business stakeholders
• Collaborating with data engineers, product teams and customer success to deliver measurable outcomes
• Acting as an internal evangelist for applied data science and innovation

What You’ll Bring

Must‑haves

• Strong understanding of machine learning techniques — clustering, NLP, deep learning
• Hands‑on experience with feature engineering, model evaluation and data exploration
• Knowledge of modern AI tooling (RAG, fine‑tuning, LLMs, agentic frameworks)
• Ability to bridge technical and commercial conversations confidently
• A logical, creative problem‑solver who can turn data into ROI

Nice‑to‑haves

• Spark / PySpark / Databricks or distributed data experience
• Familiarity with AWS (S3, EMR) or Hive‑based environments
• Consulting or enterprise B2B experience
• Exposure to causal AI, agentic systems, or LLM applications
• Join a multi‑award-winning AI innovator operating at global scale
• Work on meaningful, high‑impact AI projects with blue‑chip clients
• Hybrid setup — 3 days per week in a stunning London office
• Inclusive, high‑performance culture with genuine career growth
