Job summary

Aventum Group in London invites you to take ownership from day one, with space to grow and move as fast as you want, while you contribute to meaningful change across the delegated authority lifecycle.

You’ll work across underwriting, compliance, claims and operations, ensuring accurate, compliant, and commercially effective agreements that drive long-term growth. Expect honest feedback, accountability and real ownership in a collaborative culture.

Job description

This isn’t a job description. It’s your invitation.

At Aventum Group, we don’t hire to fill seats. We bring people in to build something real. We want people to join us (that person might be you) on our mission to be the world’s most inspiring insurance group, not by playing it safe but by delivering the unexpected and creating meaningful impact. That means backing ideas early, trusting people to own their work and giving them the space to grow faster than they thought possible. If you’re looking for rigid career paths or a one-size-fits all management, Aventum Group probably isn’t for you.

However, if you do want responsibility from day one, honest feedback and a culture that expects you to speak up, take ownership and keep getting better, then you might just be a great fit. Some people join us knowing exactly where they want to go. Others figure it out once they’re here. Both work here - the question is, will you?

What You’ll Take On (The Actual Job Description)

So you’re looking for a new challenge? This is your chance to step into a role with real responsibility. You’ll be given the space to own your work, supported to move as fast as you want and expected to keep raising the bar for yourself and the business.

Delegated authority is built on trust, technical expertise and attention to detail. This role is for someone who thrives in complexity, brings confidence to stakeholders and helps shape robust delegated authority arrangements that support long-term growth. You'll work across underwriting, compliance, claims and operations, ensuring agreements are accurate, compliant and commercially effective while driving continuous improvement across the delegated authority lifecycle. Our employer brand emphasises impact, accountability, growth and collaboration, with a focus on real ownership and meaningful contribution.

What you’ll own

• Own the creation and delivery of binding authority, reinsurance and related documentation, helping ensure every agreement is clear, compliant and fit for purpose.
• Partner with underwriters, brokers and insurers to build trusted relationships that keep delegated authority arrangements aligned and performing effectively.
• Act as the technical expert on delegated authority matters, providing guidance that drives confident and consistent decision-making.
• Strengthen governance by maintaining delegated authority frameworks and identifying opportunities to improve processes and outcomes.
• Use market knowledge and technical judgement to ensure documentation reflects the correct clauses, conditions and jurisdictional requirements.

This role is for someone who thrives on challenge, moves with pace and wants to build something that genuinely makes a difference not just maintain what already exists.

What it’s Like to Work Here

Expect high standards - and the support to meet them. Expect autonomy (not micromanagement) and the chance to collaborate across teams, brands and borders. Here, your ideas are taken seriously, wherever you sit in the business. We invest when the right tools don’t exist. We listen when our people say something can be better. And when we win, we make sure the people building the business win too. This is a place where performance matters - but so does enjoyment, curiosity and doing work you are proud of.

Who Thrives at Aventum Group?

We don’t expect you to tick every box. Experience helps, but curiosity matters more. If you are willing to learn, take ownership and ask questions when you don’t know the answer, you’re already off to a great start. We look for people who:

• Have experience relevant to the role, whether from a similar position, education or transferable skills
• Confidence in communicating with others and working together
• A mindset focused on learning, improvement and follow-through
• An interest in how things work (and how they could be improved)

If this sounds like you, you sound ready for a new chapter of challenge at Aventum Group.

Why Apply

Because you want more than a job title. Because you want to grow, not wait your turn. Because you want to be trusted to do good work (and get recognised when you do it). And because you want to help build something inspiring, unexpected and meaningful.
