What are the responsibilities and job description for the Mainframe QA Test Manager position at Randstad Digital Americas?
Job Summary
Job Overview
We are seeking a highly skilled Senior Mainframe QA Testing Engineer to design, execute, and automate comprehensive testing strategies for our core mainframe platforms. In this role, you will be responsible for ensuring the reliability, performance, and security of high-throughput, mission-critical legacy systems and their integrations with modern distributed environments.
Rather than writing application code, you will operate as a quality advocate-using a deep understanding of mainframe architectures to design robust test scenarios, execute complex batch and online transactions, validate database integrity, and drive modern test automation initiatives.
Key Responsibilities
Validate batch processing environments by writing, modifying, and executing JCL (Job Control Language).
Verify online transaction processing through CICS or IMS interfaces.
Perform comprehensive data validation of Db2 relational databases and VSAM files, writing SQL queries to perform pre- and post-test data verification.
Build, maintain, and execute automated regression test suites using tools like BMC AMI DevX Total Test (Compuware), IBM zUnit, or terminal emulator automation tools (e.g., JMeter with RTE, ACCELQ, or Micro Focus).
Create and manage mock data environments using service virtualization to limit expensive mainframe CPU usage during testing.
Document, track, and manage software defects in tools like Jira or ALM, providing clear diagnostic information to COBOL developers for swift remediation.
Collaborate closely with business analysts, system administrators, and cross-functional engineering teams to ensure integrated end-to-end system reliability.
Required Qualifications
Technical Experience
5 years of dedicated QA/testing experience specifically within enterprise Mainframe environments.
Hands-on Core Mainframe Skills: Strong familiarity navigating TSO/ISPF and managing spool files with SDSF.
File & Database Validation: Advanced proficiency with Db2 (SQL) and managing mainframe data structures (VSAM, sequential files).
Log & Execution Reading: Ability to read and troubleshoot JCL scripts and diagnose common execution Abends.
Testing Utilities: Experience using mainframe data manipulation tools such as File-AID / File Manager or InSync.
Integration Testing: Experience testing hybrid environments where modern web/mobile APIs (REST/SOAP) trigger backend mainframe processes.
Soft Skills & Competencies
The "Tester's Mindset": A strong analytical approach focused on breaking code, identifying edge cases, and validating logic limits.
Excellent written and verbal communication skills to articulate technical defects to development teams and business risks to stakeholders.
Ability to work in agile or hybrid-waterfall environments.
Desired Qualifications (Nice To Have)
Code Familiarity: The ability to read and understand (though not necessarily write) COBOL or PL/I code to perform white-box testing.
Advanced Automation: Direct experience with modern automated mainframe testing frameworks (BMC DevX Total Test, zUnit, or ACCELQ).
Scheduler Knowledge: Familiarity with batch scheduling systems like Control-M, CA7, or TWS.
Experience in high-compliance industries such as Banking, Financial Services, Insurance, or Healthcare.
