Developer of Language Parsers for Mainframe Applications Understanding

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

• Maintain and develop language parsers written in C and C++.
• Work in an agile, collaborative environment across software architecture, understanding both front-end and back-end concerns, while specializing in the back-end.
• Develop using object oriented programming, multi-threading and concurrency.
• Work with client-server architectures, networking protocols, application development, and databases.
• Understand user and system requirements for multi user solutions.
• Use and develop REST API services.

Required Technical and Professional Expertise

• C & C++ developer with at least 5 years of proven recent experience in developing and debugging UNIX/LINUX/Windows based C/C++ programs/applications.
• Deep understanding of C & C++ programming language data structures, common programming idioms, design patterns and algorithms (using common libraries like stl, boost).
• Proficiency with SQL language, experience with relational databases and schema design.
• Familiarity with Python language -for the internal tool-chain.
• Performance-oriented developer with a passion and experience in finding most optimized, performing solutions. Experience in performance profiling, memory consumption investigations and the related tools.
• Availability to learn common Mainframe specific concepts and languages: COBOL, PL/I, JCL, Assembler, transaction and hierarchical database systems (CICS, IMS) and availability to gain knowledge in lesser known languages and dialects (E.g.: Natural, IDMS, Adabas, DT Cobol, etc).

Preferred Technical and Professional Expertise

• Knowledge of lexing and parsing techniques and algorithms (E.g. top-down manual parsing, regex, grammar-based parser generators -Bison, ANTLR)
• Experience with Agile development methodologies.
• Experience with Linux specific C++ development tool-chain.
• Experience with cross cutting aspects of authentication, authorization and security. Experience building API driven interfaces.
• DevOps Experience (GitHub, CI/CD such as Jenkins, Automation such as Ansible/Python).
• Exposure to software containerization and cloud technologies (E.g.: Docker, OpenShift, K8S)
