THE COMPANY

This fast-growing consulting firm helps organisations across the public sector, defence and commercial markets deliver measurable improvements in performance through data, AI and digital solutions. They are building a modern AI & Digital capability that sits at the front of transformation programmes, working shoulder-to-shoulder with clients on their toughest operational challenges.

  • Leading technical workstreams, managing small teams and ensuring projects are delivered on time and to a high standard
  • Translating complex technical concepts into clear, compelling narratives for non-technical senior stakeholders
  • Coaching and mentoring consultants to build their capabilities in DS/ML/AI and modern analytics

YOUR SKILLS & EXPERIENCE

  • Strong background in Data Science, Machine Learning, AI, simulation or advanced analytics, with clear examples of end-to-end delivery
  • Proven ability to shape, not just execute: from defining the problem and designing the solution, through to delivery and measurement of impact
  • Consulting capability – comfortable running client workshops, identifying opportunities, influencing senior stakeholders and supporting pitches
  • Evidence of measurable commercial or operational impact (e.g. revenue growth, cost reduction, efficiency gains, service improvement)
  • Hands-on experience building models and turning prototypes into robust, production-ready solutions
  • Experience leading teams or technical workstreams in a project environment
  • UK citizenship (for security clearance purposes) and willingness to travel across the UK 2-3 days per week, depending on client needs

Nice-to-have experience:

  • Background in a consulting environment or a high-performing in-house DS/AI team
  • Exposure to sectors such as defence, public sector and consumer/retail
  • Familiarity with modern data and AI tooling such as Python, Spark, Databricks, Azure cloud, and Generative AI platforms (experience with specific tools is helpful but not essential)
  • A mix of technical, product and operational experience – comfortable talking both code and business outcome
