Introduction

This business builds practical AI solutions that actually get used — not experiments that sit on a shelf. As a Senior AI Engineer, you’ll work end-to-end on real client challenges, shaping intelligent systems from early design through to live deployment.

What You’ll Be Doing:

• Designing, building and deploying production-ready AI and data science solutions
• Training and shipping advanced machine learning, deep learning and reinforcement learning models
• Developing AI systems using Large Language Models
• Building robust data pipelines for extraction, cleaning and transformation using Python and SQL
• Exploring data through ad-hoc analysis and notebooks to uncover insights and opportunities
• Turning complex outputs into clear dashboards using tools like Power BI or Tableau
• Leading client-facing discussions, presentations and written outputs
• Championing best practice across version control, containerisation and cloud deployment
• Supporting proposals and shaping new data science opportunities
• Mentoring junior team members and setting a strong technical standard

Main Skills Needed:

• Strong background in a quantitative discipline (mathematics, statistics, physics or similar)
• Proven experience delivering AI or data science solutions end to end
• Advanced Python skills with libraries such as Pandas, NumPy and scikit-learn
• Hands-on experience with machine learning techniques (e.g. tree-based models, regression)
• Practical exposure to deep learning and reinforcement learning approaches
• Experience working with SQL and structured data
• Confidence explaining technical concepts to non-technical stakeholders
• Familiarity with collaborative engineering practices (Git, cloud environments, deployment workflows)
• Strong problem-solving ability, organisation and attention to detail

What’s in It for You:

• Competitive salary with an annual performance bonus
• 26 days’ holiday plus bank holidays — and your birthday off
• £1,000 annual personal development budget
• Private healthcare including mental health support
• Enhanced maternity and paternity leave
• Hybrid working with two days a week in the office
• Opportunity to work from abroad for up to a month each year
• A close-knit, collaborative team that values learning and impact
• Regular socials, office perks and a genuinely supportive culture
