Simplex Trading is seeking a motivated, analytically-minded Business Intelligence Analyst / Accountant to join our Finance team in our Chicago, Illinois office. This is a full-time, in-office position for a candidate who sits at the intersection of finance and technology — someone equally comfortable querying a trading database as closing the books. You will own day-to-day accounting responsibilities while also serving as a key driver of process automation initiatives and data-driven financial analysis across the firm’s proprietary databases. The ideal candidate has a strong accounting or finance foundation, hands-on SQL proficiency, and a genuine enthusiasm for replacing manual workflows with scalable, technology-driven solutions.
Annual base salary ranges from $100,000 to $120,000, and is influenced by a number of factors, including qualifications and experience. This role is also eligible for an annual discretionary bonus, which can be a significant portion of total compensation. This full time role is also eligible for other forms of compensation and benefits including health/dental/vision insurance, and 401(k) contributions.
