Summary
Tekmerion Capital Management has appointed Ziad Chammaa as head of engineering, marking a notable talent acquisition in the competitive market for technologists at hedge funds. Chammaa joins the New York-based systematic hedge fund from Meta, where he served as an engineering manager for approximately one year. Prior to Meta, he held the position of vice president of data engineering at Two Sigma, the quantitative trading firm, providing him with substantial experience in large-scale data systems and financial computing infrastructure.

Tekmerion operates as a systematic hedge fund utilizing sophisticated mathematical models paired with what the firm describes as "common sense and focused on achieving real, practical results." The firm's name derives from the Ancient Greek word "tekmerion," meaning "signal"—a thematic choice reflecting its signal-processing orientation. The hedge fund has undergone structural transitions in recent years: originally founded in 2017, it joined Brevan Howard's platform in 2024 under the designation BH-Tekmerion before being spun out as an independent entity earlier in 2026.

The fund's leadership team reflects a deep bench of experienced systematic traders. Co-founders include Zachary Squire, who studied Classics at Princeton and previously served as head of foreign exchange trading strategy and oversight at Bridgewater Associates, and Larry Mincone, whom Squire met at Bridgewater. The combination of classical education backgrounds and elite trading experience suggests an unconventional approach to systematic finance.

The appointment of Chammaa signals Tekmerion's expansion phase, evidenced by three active job openings in its New York office: positions for a software engineer, data analyst, and macro analyst. This hiring activity indicates investment in both technology infrastructure and research capacity as the fund scales its operations post-spinout from Brevan Howard.
