Jefferies Tech Stack

Global investment banking and capital markets firm with 40+ offices

Investment Banking New York City, New York 5,001–10,000 employees Founded 1962 Public Company

Jefferies operates a full-service investment banking platform across advisory, sales/trading, research, and wealth management. The tech stack reflects a financial services infrastructure: FIX, kdb+, Bloomberg, SWIFT, and Fidessa for trading and settlements; Kafka, GridGain, and SQL for data movement; Java and Python for application logic. Adopting Kubernetes, Airflow, and Snowflake signals a shift toward cloud-native data pipelines — a pattern consistent with their stated pain around cloud migrations and P&L automation. Finance roles dominate hiring (178), but engineering (50) and data (9) hiring is active, with notable openings for Equities Derivatives Development and Digital Workplace leadership.
