The Role:

As a Lead Data Scientist, you bring strong commercial experience applying data science to solve real-world business challenges. You are comfortable working across classical machine learning and emerging AI techniques, particularly in LLM/Agentic AI space.

You can move between hands-on modelling, exploring new approaches (e.g. LLMs), and explaining insights clearly to non-technical stakeholders. With a pragmatic, problem-solving mindset, you help shape opportunities and deliver impactful solutions.

You will thrive in this role if you are:

• A curious problem solver who challenges the status quo
• Comfortable bridging the gap between technical data science and client business needs
• Passionate about innovation and exploring “what’s next” in AI and ML
• Experienced in working within Agile methodologies and consultancy environments
• Keen to take ownership while supporting and guiding others

 

Role Responsibilities:

Data Science, AI & Delivery

• Work with structured and unstructured data to support model development and analysis
• Design and implement ML and AI solutions, including LLM-based and traditional approaches
• Apply techniques such as RAG, embeddings, and fine-tuning where appropriate
• Contribute to development and optimization of AI applications using established and emerging agentic patterns (e.g. tool use, orchestration, multi-step reasoning)
• Apply evaluation frameworks to assess model and system performance
• Contribute to deploying models and supporting them in production using engineering and MLOps best practices
• Stay up to date with emerging AI techniques and experiment with new approaches, tools, and frameworks

Problem Scoping & Client Engagement

• Translate business questions into clear data science approaches
• Communicate results and insights to technical and non-technical stakeholders
• Contribute to identifying opportunities where data science and AI can add value
• Support project scoping and provide guidance to less experienced team members when needed

 

Must have Qualifications:

• 5+ years of experience in Data Science or Analytics
• Strong foundation in machine learning and predictive modelling
• Exposure to Generative AI concepts (e.g. LLMs, RAG, fine-tuning, prompt engineering)
• Strong programming skills in Python and SQL
• Familiarity with cloud-based solutions (e.g. GCP, Azure, AWS)
• Experience working with real-world, production data problems
• Ability to communicate technical concepts clearly to non-technical stakeholders

 

Nice to have Qualifications:

• Experience in consulting or client-facing environments
• Hands-on experience designing and deploying Generative AI solutions, including Agentic AI systems.
• Experience with MLOps practices and taking models into production environments
• Exposure to modern data engineering practices and integration with data pipelines
• Awareness of Responsible AI practices (bias, evaluation, safety)
