- • Millennium's hiring reflects the multistrategy hedge fund's strategy to build low-latency trading infrastructure and algorithmic execution capabilities to compete with electronic trading firms like Jane Street.

Summary
Millennium Management has secured two senior technology managing directors from major Wall Street institutions, underscoring the continued competitive pressure on investment banks to retain top technology talent and reflecting hedge funds' strategic pivot toward building proprietary electronic trading infrastructure.
Katarina Hunt, most recently Goldman Sachs' global head of engineering for equity derivatives and equity risk, has joined Millennium's London office as head of risk engineering. Hunt's 13-year tenure at Goldman Sachs culminated in her elevation to managing director five years prior to her departure. She represents the profile of fast-rising technologist that has become increasingly attractive to alternative asset managers: she was identified as one of Goldman's fastest-rising vice presidents over a decade ago before advancing to the partnership level.
Simultaneously, James Clennell departed JPMorgan to assume the role of head of credit technology at Millennium's New York office. Clennell's career trajectory at JPMorgan spanned more than two decades, beginning in the middle office before advancing to managing director in 2024. His most recent position was global head of credit trading and risk management technology. He departed JPMorgan in late 2025 and spent the first half of 2026 working on a motorsports data platform before joining Millennium.
The dual hiring underscores a broader talent migration pattern as hedge funds intensify investments in technology infrastructure. Millennium's recruitment strategy extends beyond traditional banking talent. In April 2026, the firm brought on Alexandre Fournier, the former chief technology officer of Tower Research Capital, for a senior role within its algorithmic execution team. This pattern reflects Millennium's competitive positioning against electronic trading firms like Jane Street, which have increasingly attracted capital and top technologists. To remain competitive, multistrategy hedge funds are now building out low-latency architecture and proprietary algorithmic trading systems that rival those of pure electronic trading platforms.
Millennium Management declined to comment on these personnel changes.
