About The Team

Our London-based Marine & Aviation Reinsurance team writes a broad range of Marine, Energy and Aviation treaty reinsurance products for a global client base. We combine specialist underwriting expertise, advanced analytics and meaningful capacity to deliver innovative solutions and high-quality service to brokers and clients worldwide.

We are an established market participant with an ambitious outlook. Our underwriters are expected to bring an adaptable mindset, strong analytical capability, commercial judgement, entrepreneurial thinking and a collaborative approach.

The Opportunity

We are looking for a talented individual to join our London team. You will initially support the Marine, Energy and Aviation underwriting teams and, as your capability develops, take on increasing underwriting responsibility with the goal of underwriting autonomously within agreed authorities.

Success in the role will be demonstrated through technical excellence, sound portfolio judgement, responsive broker service, effective collaboration and a constructive willingness to challenge established thinking.

What You Will Be Doing

  • Analyse and underwrite individual opportunities and the wider portfolio using available rating, exposure-management and modelling tools.
  • Identify practical ways to improve underwriting tools, data quality and analytical processes.
  • Provide proactive, timely day-to-day underwriting service to brokers and cedants.
  • Support the Marine & Aviation team across a broad range of underwriting, portfolio-management and administrative responsibilities.
  • Develop trusted relationships with brokers and clients, supporting the production of additional profitable business.
  • Work closely with modelling, actuarial, claims and operations colleagues to deliver efficient and joined-up underwriting processes.
  • Take ownership of selected relationships with external providers of aggregate-monitoring software.
  • Maintain accurate underwriting records and contribute to portfolio monitoring, planning and reporting.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
