Global XB Technical Subject Matter Expert

Global XB Technical Subject Matter Expert London Market Insurance | Global Broking Systems | Application Support | Hybrid (Milton Keynes – 1 day per week)

Do you have deep technical expertise supporting Global XB within the London Market insurance sector?

Have you worked with one of the major insurance brokers supporting business-critical broking applications, resolving complex issues, configuring systems and advising users?

If so, we'd like to hear from you.

We're recruiting on behalf of one of the world's leading insurance groups, employing over 24,000 people across 56 countries. Employee ownership sits at the heart of their business, creating a collaborative culture where technical expertise is valued and long-term careers are built.

As part of continued investment in their London Market technology estate, they're looking for an experienced Global XB Technical Subject Matter Expert to become the technical authority for one of their most critical business applications.

Global XB remains a core platform supporting complex commercial insurance and reinsurance operations across the London Market.

While the platform is now classed as a heritage solution by DXC, it continues to underpin many major insurance brokers, with organisations gradually modernising their technology estates over several years rather than replacing core broking systems overnight.

Within this business, Global XB supports around 1,200 users, with a further 400 users scheduled to migrate onto the platform as part of an ongoing transformation programme.

You’ll play a pivotal role in ensuring the platform remains robust, reliable and well supported while helping shape its future.

This is far more than a traditional support position.

You’ll become the recognised technical expert for Global XB, providing third-line application support, troubleshooting complex issues, advising the business on technical solutions and helping improve the overall support capability of the team.

Working closely with Business Systems, Infrastructure, Development and business stakeholders, you’ll support both day‑to‑day operations and strategic change initiatives.

You’ll also mentor colleagues, share your expertise and help develop the wider Application Support team's capability around Global XB and London Market systems.

• Provide Level 3 support for complex incidents and application issues.
• Troubleshoot, investigate and resolve production problems.

Perhaps you've worked for organisations such as Gallagher, BMS, Price Forbes, Miller, Howden, RFIB, Ardonagh, Lockton or another London Market broker supporting Global XB or similar broking platforms.

While Global XB experience would be highly advantageous, we’d also welcome applications from professionals who have supported comparable London Market broking platforms and can demonstrate a strong understanding of insurance operations and enterprise business applications.
