Marsh Description: The Head of Cyber Reinsurance Actuarial leads the actuarial function supporting cyber reinsurance broking and advisory at Marsh Re. This role is accountable for developing and maintaining cyber actuarial analytics, translating model outputs into actionable placement and portfolio insights, and partnering with broking, analytics, and advisory teams to deliver high-quality client and market solutions.

We will count on you to: Own the actuarial strategy for cyber projects aligning analytics to placement needs and client objectives. Lead cyber pricing and portfolio analytics, including experience analysis, exposure/rate adequacy views, and scenario and stress testing to support structuring and negotiation. Develop and oversee actuarial methodologies for cyber (frequency/severity, tail risk, aggregation, systemic/catastrophe-style events), including model governance, assumptions, and limitations documentation.

Translate technical results into clear client-facing insights and materials for submissions, renewals, and stewardship reviews (e.g., key drivers, sensitivities, uncertainty ranges). Partner closely with broking to support market strategy, reinsurer engagement, and deal execution; provide actuarial support in negotiations where needed. Establish strong peer review and quality controls for actuarial work products, consistent with professional standards and internal governance expectations for analytics work.

Build and manage a high-performing cyber actuarial team (hiring, coaching, development, workload prioritisation), fostering a culture of technical excellence and commercial impact. Contribute to thought leadership (market insights, benchmarking, and research) that supports the firm’s cyber positioning with clients and reinsurers.

What you need to have: Qualified actuary (FIA/FCAS/FSA or equivalent), with significant post-qualification experience in (re)insurance pricing and portfolio analytics. Prior experience in cyber (re)insurance, including cyber pricing and portfolio analytics and/or cyber tail risk/aggregation/systemic risk considerations. Demonstrated expertise in building and governing actuarial models and methodologies, including documentation of assumptions, limitations, and uncertainty.

Proven ability to translate complex technical outputs into clear, client-ready insights and commercially actionable recommendations for placements and portfolio strategy. What makes you stand out? Strong understanding of reinsurance structuring and the broking lifecycle, with credibility in supporting negotiations and reinsurer engagement. Thought leadership track record (market insights, benchmarking, research, or external speaking/publishing) in cyber or specialty (re)insurance analytics.

Experience leading and developing high-performing teams, including hiring, coaching, and setting quality/peer review standards.
