Sr. Assembler developer

Introduction
At IBM, work is more than a job – it’s a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you’ve never thought possible. Are you ready to lead in this new era of technology and solve some of the world’s most challenging problems? If so, lets talk.

Your Role and Responsibilities
The IBM Compilation Technology team is looking for an assembler developer to join our mission to deliver leading-edge compiler offerings. The IBM Compilation Technology team is known for developing world-class compilers and runtimes. Our squads are autonomous, multi-disciplinary teams, consisting of talented software developers with knowledge in new and up and coming language standards, hardware design, compiler optimization expertise, contribute to the open source and proprietary compiler technologies, and proven software development skills.

In this position, you will be working on modernizing, developing and supporting High Level Assembler (HLASM) on IBM System Z mainframes. You will work with internal and external clients to define requirements, develop new features and improve legacy mainframe development environments in general. You will also perform maintenance activities by responding to high severity problems and cases, performing problem diagnosis, providing fixes and regression testing fixes.
