Investment Management Chicago, IL 201–500 employees Founded 1982 Privately Held

Gelber Group is a Chicago-based proprietary trading firm founded in 1982, now in active hiring mode with 17 open roles and accelerating velocity. The tech stack is Python-heavy (Pandas, NumPy, SQL) on Microsoft infrastructure, but remarkably thin on engineering headcount (1 engineer against 15 finance roles), suggesting trading strategies and research drive the product roadmap while infrastructure remains relatively static. Current focus is Brazil market entry—multiple projects cite rates trading and derivatives expansion—paired with European footprint growth.
