MS Reinsurance has announced that group chief underwriting officer Charles Goldie (pictured above, left) will retire from the company effective April 1, 2026, after five years in the role, with Jörg Bruniecki set to succeed him as group CUO.
Goldie will remain with MS Reinsurance as senior advisor to CEO Robert Wiest.
Jörg Bruniecki (pictured above, right), currently CUO of Global Specialty Lines, will oversee MS Reinsurance’s global underwriting strategy, reporting directly to Wiest and joining the leadership team and executive board.
The move marks the latest step in a long-running collaboration between Goldie and Bruniecki, who previously worked together at PartnerRe before both joined MS Reinsurance.
Bruniecki brings three decades of reinsurance experience, having held senior roles at Munich Re and PartnerRe before joining MS Reinsurance in March 2022 as CUO of International P&C. He most recently led Global Specialty Lines, covering agriculture, financial risks, cyber, engineering, and complex industrial and corporate risks.
Wiest described Goldie as “a defining force in MS Re’s evolution,” crediting his leadership with reshaping the underwriting portfolio and strengthening the firm’s market position. On Bruniecki, Wiest said the incoming CUO had shown “strategic clarity and a deep understanding of the value we create for our partners.”
Goldie said it had been “a privilege to help lead MS Reinsurance during a period of significant growth and change.”
The leadership reshuffle follows a broader reorganization completed in July 2025, when MS Reinsurance unified its global specialty lines under a single structure and reorganized its Americas and International P&C units. At the time, the company said the overhaul was intended to bring underwriting teams closer to clients and sharpen focus on specialty risk.
Those changes have since been reflected in improved metrics, although these results are already in the public domain and not new. Earlier 2025 disclosures showed net income rising to about $341 million for the first nine months of the year, up from roughly $222 million a year earlier, while full-year 2024 gross written premiums grew to around $3.6 billion.
In a separate move effective April 1, Louis de Segonzac will transition from CUO of the Americas to chief technical underwriting officer, replacing Marcus Pollak.
The CTUO function oversees technical underwriting and pricing, risk analytics, and underwriting operations, providing the analytical backbone to the group CUO’s market-facing mandate. The company has indicated that de Segonzac’s regional leadership experience will be used to further modernize these capabilities.
The changes leave several key seats still to be filled. MS Reinsurance has said it is conducting an internal and external search for remaining open roles, understood to include the CUO positions for the Americas and Global Specialty Lines.
