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.

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

• 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

• 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)
