Fidelity operates at massive scale—$15 trillion AUA, 77,000+ employees—with a tech stack spanning legacy core systems (COBOL, CICS, z/OS, mainframe storage) and modern cloud infrastructure (AWS, Azure, Snowflake, Spring Boot). Active adoption of infrastructure-as-code (Terraform, Helm, CloudFormation) and Microsoft automation (Power Apps, Power Automate) signals a modernization push toward cloud-native deployments, while hiring remains broad across engineering, sales, and finance with notable leadership gaps in AI architecture and project delivery—areas where Fidelity is explicitly recruiting.
