Catastrophe Modelling Analyst in Slough

This is a great job for an experienced catastrophe modeller who’s ready to take a lead role in managing catastrophe risk for one of the UK’s largest general insurers. You’ll drive accurate, efficient, and regular reporting of property exposure, while maintaining robust controls that build trust across a wide range of stakeholders. Your strong communication skills will help translate complex data into actionable insights, showing the value of a high-performing exposure management function. You’ll have the chance to demonstrate initiative and insight, validating catastrophe models to support the integration of Direct Line brands into Aviva Group—helping unlock capital benefits that ultimately enhance our ability to serve customers with the best insurance solutions.

A bit about the job: You’ll compile exposure data into a standardised format across Direct Line to support catastrophe modelling. You’ll be accountable for making sure the data is accurate, complete, and fit for purpose—through proactive validation and stakeholder engagement. You’ll quantify catastrophe risk using modelling software (manual and API-based) and explain the results clearly. You’ll collaborate with actuarial teams to input modelled and non-modelled catastrophe perils into the internal model. You’ll lead quarterly risk reporting via the Catastrophe Risk Forum, delivering insights and monitoring Key Risk Indicators for stakeholders across Pricing, Underwriting, Risk, Actuarial, and Finance. You’ll help shape and defend our view of catastrophe risk, using claims data, up-to-date research and internal expertise to meet regulatory expectations and support integration with Aviva Group. You’ll also support ad hoc internal queries and external reporting. You’ll play a key role in the reinsurance purchase by managing exposure data submissions, coordinating with brokers, and ensuring timely, accurate data for reinsurance placement. You’ll take the lead in compiling accurate reports for regulatory submissions, such as those required by the PRA. And when severe weather events occur, you’ll help support our customers by providing timely, accurate data back to the business.

Skills and experience we’re looking for:

• Proven experience in catastrophe modelling (Verisk, Moody’s and/or JBA), including preparing input data, running models, and interpreting results with precision.
• Strong programming/scripting skills in R or Python. Experience using web APIs. SQL knowledge is a plus.
• Excellent communication skills—able to translate technical concepts into clear, actionable insights for diverse stakeholders.
• Familiarity with actuarial principles such as inflation projections, loss trending, and frequency-severity modelling.
• Strong project management skills—able to plan, manage and deliver tasks independently and collaboratively.

What you’ll get for this role: Our purpose - with you today, for a better tomorrow – is a promise we make to our colleagues too. And one of the ways we live up to that promise is by investing in you. We have so much to offer when it comes to being an Aviva colleague. Starting salary between £60,000 and £70,000 (depending on location, skills, experience, and qualifications). Bonus opportunity - 10% of annual salary. Actual amount depends on your performance and Aviva’s. Generous pension scheme - Aviva will contribute up to 14%, depending on what you put in. 29 days holiday plus bank holidays, and you can choose to buy or sell up to 5 days. Aviva-funded Private Medical Benefit to help you get expert support when you need it. Make your money go further - Up to 40% discount on Aviva products, and other retailer discounts. Up to £1,200 of free Aviva shares per year through our Matching Share Plan and share in the success of Aviva with our Save As You Earn scheme. Brilliantly supportive policies including parental and carer’s leave. Flexible benefits to suit you, including sustainability options such as cycle to work. Make a difference, be part of our Aviva Communities and use your 3 paid volunteering days to help others. We take your wellbeing seriously with lots of support and tools.
