Senior Manager – Capital (P&C Actuarial)
Oliver Wyman Actuarial | London (hybrid)
Capital is one of the fastest-growing areas of our UK practice, with a pipeline spanning some of the most high-profile work in the P&C market – from major model changes and IMAP applications to large-scale platform migrations and self-build internal models. We are looking for an ambitious Senior Manager ready to lead that delivery and become one of our future leaders.
The Opportunity
Oliver Wyman’s Actuarial practice is rapidly expanding in the UK, backed by a hugely successful global P&C business and the wider Marsh group. This role sits at the heart of that growth: you will lead the delivery of our flagship capital engagements, bring deep technical insight to clients, and help us shape and build our growing team to win the next generation of large-scale projects. At the same time, we are using AI to transform our approach to actuarial work – in particular capital modelling, transformation and self-build tools – and you will be at the forefront of bringing this to our clients.
What You Will Do
· Deliver varied, interesting capital engagements: Play a leading role in the delivery of a variety of capital-related engagements spanning the Lloyd’s market and UK & global insurers, including building and nurturing client relationships.
· Bring technical depth across: internal model design, calibration and parameterisation; independent validation; major model change and IMAP applications; model platform migrations; M&A capital diligence, Solvency II/UK and Lloyd’s capital requirements.
· Own senior stakeholder relationships: act as a trusted adviser to Chief Actuaries, CROs, CFOs, Boards and regulators; present challenging or complex results with clarity and confidence.
· Grow the team: coach and develop junior consultants, lead teams, and help recruit as we scale.
· Build the business: support proposals, tenders, thought leadership and client development to help win and deliver future large-scale projects that amplify our success.
What We Are Looking For
· 8+ years of P&C actuarial experience with deep expertise in capital modelling, ideally including consulting experience.
· Qualified actuary (FIA or equivalent).
· Strong knowledge of the Lloyd’s market and its capital framework, plus Solvency II / Solvency UK internal models.
· Hands-on experience with at least one major capital modelling platform (e.g. Igloo, Tyche, ReMetrica); coding skills (R, Python) an advantage.
· Excellent stakeholder engagement and communication skills – comfortable challenging and advising at Board and regulator level.
· A proven track record of leading teams and delivering complex, multi-workstream projects
· AI-savvy; genuinely enthusiastic about using AI to solve challenging problems, and keen to help shape how it changes actuarial work
· Ambition: a self-starter who wants to help build a business, not just run engagements.
