Lead / Principal Consultant (AI & Data Science), London

Overview

I'm hiring multiple senior hires to join a growing AI and Digital Transformation consulting practice within a premium consultancy. This team has recently secured significant investment and is scaling quickly, with multiple hires across Lead and Principal level.

This is a role for people who want to own and deliver real AI transformation, not just advise on it.

Where you fit

You'll sit within the Digital / AI Consulting practice, working directly with clients to:

• Identify opportunities for AI and advanced analytics
• Design and deliver solutions end‑to‑end
• Embed those solutions into real business operations

This is a hands‑on leadership role - combining delivery, client engagement, and mentorship of other consultants.

What you'll be doing

• Lead the design and delivery of AI and data science solutions (LLMs, NLP, ML, etc.)
• Work directly with senior client stakeholders to shape and deliver solutions
• Build and deploy end‑to‑end AI products, not just prototypes
• Apply technologies such as LLMs, RAG systems, and agentic workflows to real business problems
• Translate technical outputs into clear commercial value and measurable impact
• Mentor and develop consultants, helping build capability across the team
• Help shape the consultancy's AI offering and go‑to‑market approach

Example work

• Using LLMs to improve decision‑making and workflow automation in complex environments
• Delivering predictive analytics in healthcare to improve outcomes and efficiency
• Building AI‑driven optimisation tools in retail to improve pricing and margins
• Supporting large‑scale programmes across defence and public infrastructure

Core requirements

• Strong data science / machine learning background
• Experience delivering AI / GenAI solutions (LLMs, NLP, etc.)
• Proven ability to take solutions from concept through to real‑world deployment
• Experience leading projects, workstreams, or teams
• Strong stakeholder engagement skills - client‑facing and commercially focused
• Evidence of measurable impact (revenue uplift, cost savings, efficiency gains, etc.)

Nice to have

• Consulting experience (highly preferred)
• Experience across regulated or complex sectors (defence, public sector, retail, etc.)
• Familiarity with modern stacks (Python, cloud, Databricks, APIs, etc.)
• Experience mentoring or leading junior team members

Why this role

• Shape and scale a growing AI consulting capability
• Work on complex, high‑impact projects across multiple industries
• Strong blend of technical delivery, commercial impact, and leadership
• High visibility internally and with clients
• Opportunity to progress to partner level over time

Working style

• London base (or nearest office)
• Hybrid working, with regular client travel
• 3 days total per week
• Flexible, project‑led environment

Interview process

• Online assessment (incl. logical / aptitude test)
• Informal first conversation (director‑level, including short presentation)
• Final stage onsite in London (presentation + discussion)
