How does this role contribute to our collective success?  Data and analytics are of critical importance for AXIS. We turn data into information so the business can make decisions with confidence, identify opportunities early, and operate more efficiently. The Lead Applied Scientist is the senior scientific authority in the Data Science and AI Delivery team and is responsible for the quality of the AI the team produces, much of which now uses large language models and agentic approaches.

The role leads this work from the point a business problem is framed, through the choice of approach and the build itself, to how the resulting solution is evaluated, validated and monitored in production. Working alongside the engineering lead, it sets the scientific standards that give the business confidence in what the team delivers.
What will you do in this role?  You will lead the team’s approach to solving business problems through advanced analytics and AI, guide how solutions are designed and built, and continue to contribute directly to technical work such as model development, experimentation, code review and solution architecture. You will lead the design and development of the team’s AI and ML solutions, choosing the right approach for each problem, with large language models and agentic AI increasingly central to the work.

You will bring mathematical and statistical rigor to how problems are framed, how uncertainty is handled, and how the team judges whether a solution is good enough. You will build and evaluate solutions to the most demanding problems the team takes on, review the work of others to keep standards high across the delivery scrums. and act as the point of escalation for difficult technical decisions.

You will hold sign-off on scientific approach and solution quality.
In this role you will be responsible for:
Leading the design and development of the team’s AI/ML solutions, and framing business problems so that the right approach can be chosen and the result measured against clear success criteria.
Leading the design of generative and agentic AI solutions, including prompting, retrieval augmented generation, tool use and multi‑step agent workflows, and the techniques needed to make them accurate and reliable.
Selecting the right approach for each problem, with large language models and agentic AI to the fore, and drawing on deep learning, machine learning and statistical methods where they are the better fit.
Owning the evaluation and accuracy methodology for the team’s models, agents and AI systems, including the metrics, test sets and acceptance thresholds that govern performance, with proper treatment of uncertainty and statistical significance, and the monitoring needed to detect drift in production.
Leading the team’s responsible AI work, including bias and fairness testing, explainability, and validation of model and agent behavior against regulatory expectations.
Solving the team’s most challenging problems, such as extracting information from unstructured documents, automating expert workflows with agents, optimization, forecasting, and portfolio and claims…
