Calamos Investments Tech Stack

Global asset and wealth management firm with liquid alternatives focus

Financial Services Naperville, Illinois 201–500 employees Founded 1977 Privately Held

Calamos is a diversified asset manager built on traditional finance infrastructure—Excel, Bloomberg, Salesforce, and trading venues like MarketAxess and Tradeweb—combined with modern data stack components (Databricks, PySpark, Delta Lake). The hiring profile is sales-heavy (8 open roles in sales vs. 1 engineering) with a notable recent security hire (Cybersecurity Director), reflecting both revenue growth focus and rising compliance/risk pressures in alternatives and crypto products (Bitcoin ETFs in specialties). Pain points cluster around sales execution, asset retention, and system reliability under trading stress—classic signals of a scaling wealth manager.
