Senior Capital Actuary

Flexible working: this role is offered on a hybrid basis, with a blend of home and office working.

We’re looking for a Senior Capital Actuary to play a key role in delivering our regulatory and economic capital modelling, supporting both Solvency II reporting and strategic decision-making across the business.

Sitting within our Capital Modelling team, you’ll contribute to the development and ongoing enhancement of our Internal Model (Igloo) ensuring it remains robust, compliant, and aligned to business needs. You’ll work closely with stakeholders across the organisation, translating complex modelling outputs into clear, actionable insights for senior leaders, committees, and regulators.

Alongside hands‑on technical delivery, you’ll also support and mentor more junior actuaries, helping to shape the future of the team.

You’ll play a key role in contributing to the production of both regulatory capital (Solvency II) and internal economic capital requirements, while supporting the ongoing development and maintenance of the Internal Model. This includes hands‑on involvement in Igloo coding, parameter updates, and governance enhancements, alongside improving the calculation kernel and parameterisation processes in line with regulatory expectations, validation findings, and industry best practice.

You’ll help ensure the model remains fully compliant, responding to regulatory feedback and proactively identifying, assessing, and escalating any limitations or risks. As part of the annual model update cycle, you’ll work across the full end-to-end process, from data validation and analysis through to parameter setting, model design and build, testing, calibration, validation, and stress and sensitivity analysis. Alongside the technical work, you’ll produce clear and insightful reports for senior stakeholders and regulators, translating complex outputs into meaningful, decision-useful insights.

You’ll also build strong relationships across the business and support the development of junior team members, helping to strengthen overall team capability.
