Software Engineer III (Mainframe)

Quick Facts

• Role: Software Engineer III (Mainframe)

Description

Join an agile team to design, develop, and troubleshoot secure, scalable mainframe software solutions and production code. You will translate high-level designs into detailed technical designs, create architecture/design artifacts, and tune performance while following SDLC and IT control policies. You’ll also use enterprise-authorized AI-assisted development tools, validating AI outputs for correctness, security, and quality.

Responsibilities

• Execute software solutions including design, development, technical troubleshooting, and problem solving beyond routine approaches

• Create secure, high-quality production code and maintain algorithms for synchronous execution with appropriate systems

• Use enterprise-authorized AI coding assist tools to generate/refactor code, create unit tests and documentation, and improve delivery speed—validated via peer review and automated testing

• Apply tools within the SDLC toolchain and AI-assisted automation capabilities to improve automation value

• Produce architecture and design artifacts for complex applications and ensure design constraints are met by code

• Gather, analyze, synthesize, and create visualizations/reporting from large data sets to support continuous improvement

• Identify hidden problems and data patterns to improve coding hygiene and system architecture

• Participate in software engineering communities of practice and events exploring new technologies

• Design and develop Mainframe batches; participate in design/code reviews; incorporate performance requirements and provide input to information/data flow

• Comply with project life cycle methodology and IT control policies; incorporate corporate architectural standards into application specifications

• Identify system platform components/dependencies, document application specifications, analyze performance issues, and recommend resolutions

Requirements

• Formal training or certification on software engineering concepts and 3+ years applied experience

• Hands-on experience with enterprise-authorized AI-assisted software development tools; ability to critically evaluate, validate, and refine AI outputs for correctness, performance, and security

• Knowledge of responsible AI use in engineering workflows, including data sensitivity, secure input/output handling, and resiliency/security expectations

• Flexibility to react quickly to changing business needs

• Hands-on experience with COBOL, DB2, MVS Utilities, VSAM, and JCL

• DB2 proficiency: create views, write stored procedures, and perform code tuning

• Working experience with TOPAZ/IDZ, SORT, SPUFI, PLATINUM, XPEDITER, FILEAID, CHANGEMAN, FTP, NDM

• Knowledge of enterprise SDLC standard process and management tools such as JIRA

• Ability to translate high-level design to detailed technical design and implementation; ownership of business-critical and complex processes

• Knowledge of distributed technologies and agility in picking up new technologies
