About the company

Trillium Trading is a proprietary trading firm active in US, Canadian, and OTC equities. Its core activity is trading using in-house developed technology, tested and optimized by its engineers in collaboration with traders to create tools that support fast, informed decisions in the markets. The company’s products are trading workflows and software that help traders execute and manage strategies efficiently, rather than consumer-facing software. What sets Trillium apart is its combination of long-term experience (a 20-year track record of growth and profitability), in-house, engineer-trader collaboration, multiple trading floors, and a culture of problem-solving and independent thinking. The firm also emphasizes social impact through its philanthropic initiative, Trillium Cares, which funds education, social equity, and humanitarian aid. The goal is to seize market opportunities and grow profitability while giving back to communities.

What believers are saying

  • Trillium posted late-2026 hiring for traders, internships, and candidate profiles.
  • Leadership remained stable with Ben Baller as Managing Director of Trading since January 2023.

What critics are saying

  • FINRA’s 2010 $1 million case still defines Trillium’s compliance reputation.
  • Fall 2026 trader spots filled by February 2026, limiting fresh hiring pipeline.
  • A 2026 SEC filing flip on Rubico signaled reporting noise and control risk.

What makes Trillium unique

  • Trillium still runs 3 trading floors with 150+ traders and 50+ support staff.
