Senior Property Treaty Underwriter (Hybrid - 80-100% working degree)

As a Senior Property Treaty Underwriter, you will be at the heart of our UKI & London Market property reinsurance business — evaluating risk, driving decisions, and shaping the future of our portfolio. You'll be a key face for our clients and brokers, combining technical expertise with relationship excellence.

Key Responsibilities

• Underwrite new and renewal Property treaty business within the UKI & London Market portfolio, ensuring decisions are aligned with company guidelines and appetite
• Review reinsurance submissions and documentation to determine eligibility, assess risk factors, and evaluate overall portfolio fit
• Analyse underwriting data using Swiss Re's proprietary tools — including loss history, exposure data, financial statements, and market trends — to make well-informed bind or decline decisions
• Calculate and negotiate appropriate premiums based on thorough risk assessment, balancing competitiveness with portfolio sustainability
• Build and manage relationships with clients and brokers, serving as a trusted and knowledgeable point of contact in the market
• Collaborate with internal stakeholders including Client Management, Claims & Reserving, Solutions, and Transactions teams to deliver integrated, client-focused outcomes
• Contribute to portfolio steering and appetite refinement, supporting the maintenance of a sustainable, resilient, and profitable book of business

About the Team

We are a team of 7 Underwriters spread across two locations — London and Zurich — focused on Property London Market business, which includes UK & Ireland domestic companies and Lloyd's syndicates.

You'll be joining an environment that values shared knowledge, open communication, and a collective drive to deliver excellent results for our clients.

About You

You are a highly motivated and driven reinsurance professional who combines deep technical knowledge with the interpersonal skills to influence, inspire, and connect. You bring a proactive mindset to everything you do — whether that's solving a complex risk challenge or building a key broker/client relationship.

• Strong analytical capability , with experience using data — including loss history, exposure data, and financial statements — to drive underwriting decisions
• Proven ability to build and maintain valuable relationships with external partners, brokers, and clients

These are additional nice to haves:

• Experience in Primary Property underwriting, which would complement your reinsurance background
• Familiarity with Lloyd's market operations and syndicate structures
• Experience with portfolio steering and appetite management at a strategic level
• Outstanding problem-solving aptitude with a creative and innovative approach to complex challenges
• A university degree or equivalent qualification in a relevant discipline
