Role: Full Stack Developer React.JS/Spring boot/Mainframe

Location: Austin, TX or Warren, MI - ONSITE

Duration: 24 Months

Role Overview:

In modern mainframe development, developers use frontend libraries like React to build

mainframe assets through established API gateways.

Key Responsibilities:

Develop user-friendly web applications using frontend libraries like React.

Process and modify data stored on an IBM z/OS operating system.

Utilize IBM z/OS Connect as an API gateway to transform mainframe assets (like

CICS, IMS, or Db2 programs) into standard RESTful APIs.

Make standard fetch or axios calls from the React frontend to API endpoints

without needing to understand mainframe-specific languages.
