Job description

Role: Mainframe Assembler

Location: Wilmington, DE - Onsite

Type: Contract

Job Description:

Design, coding, and testing: Mainframe assemblers are responsible for designing, coding, and testing application programs using the IBM Assembler language. They should also be familiar with the entire Software Development Life Cycle (SDLC) and have a solid understanding of mainframe operating systems, such as z/OS.

Debugging and troubleshooting: They perform debugging and troubleshooting of mainframe applications to ensure they function correctly and efficiently.

Documentation: Mainframe assemblers may also be responsible for documenting the design of the assembler programs, explaining how they work, and providing guidelines for their use.

Technical support: They provide technical support for mainframe systems, optimizing performance, and ensuring compliance with coding standards and technical design.

These assemblers work closely with system architects and analysts to understand the requirements and specifications of a system, and then translate these into efficient, low-level machine code. They must keep themselves updated with the latest mainframe technologies and assembler programming techniques to ensure the continuous functionality and reliability of mainframe systems.
