Swiss-based global reinsurance company MS Reinsurance (MS Re) has announced that its Group Chief Underwriting Officer (CUO) Charles Goldie will retire on April 1, 2026 and will be succeeded by Jörg Bruniecki, current CUO of Global Specialty Lines.
Goldie retires after five years as the company’s CUO. He will continue to support the company as a senior advisor to MS Re CEO Robert Wiest.
In his new role, Bruniecki will be responsible for the company’s global underwriting strategy. He will join the leadership team and executive committee and report directly to the CEO.
He has 30 years of experience in the reinsurance industry and joined MS Re in March 2022 as chief operating officer of the company’s international business.

Prior to joining MS Re, Bruniecki served as global head of client and broker management at PartnerRe.
He has also held various senior leadership roles at Munich Re, including Global Head of Aviation Reinsurance and Senior Executive Manager for Central and Southern Europe.
“Charles has been a decisive force in the development of MS Re,” said Wiest. “His vision, discipline and leadership have helped fundamentally reshape our underwriting strategy, strengthened our market position and created the momentum to propel us into our next chapter. Beyond that, Charles has been a trusted partner to me personally and a widely respected voice throughout our organization. We are deeply grateful for his service and wish him well in his retirement.”
Wiest added: “Jörg has demonstrated strategic clarity and a deep understanding of the value we create for our partners. His extensive market experience and ability to translate strategy into results make him ideally suited to lead our underwriting organization into its next phase.”
“It is a privilege to help lead MS Re during a period of significant growth and change,” commented Goldie. “I am proud of the team our underwriting team has built and the discipline, creativity and client partnerships that define us today. I am particularly pleased to see Jörg step into the CUO role.”
“I am honored to build on the strong foundation established by Charles,” Brunetsky said. “In recent years, we have strengthened our underwriting capabilities and deepened our relationships with clients and brokers. I look forward to working with the team at Microsoft Re to continue to create value for our partners.”
MS Re also announced the appointment of Louis de Segonzac (currently CUO Americas) as its new Chief Technology Underwriting Officer, effective April 1, 2026. He will report to the Chief Executive Officer and be a member of the leadership team.
De Segonzac succeeds Marcus Pollak, who is stepping down as chief technical underwriting officer.
De Segonzac has successfully led MS Re’s Latin America market since 2014 and the broader Americas region since 2021, continuing to drive underwriting performance. He will leverage his underwriting experience and technology insights to further modernize and advance the company’s technology underwriting capabilities.
“MS Re is moving into the next phase of its transformation,” said Wiest. “These changes reflect our recognition of the contributions of Charles and Marcus and our confidence in leaders who will build on the strong foundation we have built to date.”
