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.
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)
