Our compensation policies and practices have been designed to allow colleagues to progress through the salary range over time as they progress in their role. The base pay actually offered may vary based upon the candidate's skills and experience, job-related knowledge, geographic location, and other specific business and organizational needs.

Job Description:

The Quality Engineer II – Mainframe is a hands-on role accountable for leading comprehensive end-to-end quality engineering activities for assigned medium-to-high-complexity initiatives. The role develops and executes test strategies and plans, validates mainframe batch and online processing, maximizes appropriate automation, manages quality risks and defects, and provides an evidence-based quality recommendation for release readiness.

Delivery Accountabilities

Own the quality engineering approach, detailed planning, estimates, coverage, execution oversight and quality outcomes for assigned mainframe initiatives of medium-to-high complexity.
Review business requirements, solution designs, technical specifications and data mappings; identify testability gaps, dependencies and risks early in delivery.
Design and execute end-to-end functional, system, integration, regression, negative, batch, online and implementation-readiness testing across mainframe and connected distributed or API channels.
Validate COBOL processing, JCL and procedures, IMS transactions, DB2 and IMS data, VSAM and sequential files, reports, interfaces and downstream outputs.
Prepare and control test data; perform pre- and post-execution data validation through SQL, file comparisons, job output and reconciliation checks.
Submit and monitor batch jobs, review return codes, spool output and system logs, and investigate common abends or processing failures using TSO/ISPF and SDSF or equivalent tools.
Develop, maintain and execute resilient automated regression tests; integrate suitable tests into CI/CD/continuous testing pipelines and promote reusable test assets.
Apply risk-based, shift-left, BDD/TDD and defect-prevention practices; validate user stories, acceptance criteria, Definition of Ready and Definition of Done with delivery partners.
Lead defect triage for assigned scope, provide clear evidence and diagnostic details, coordinate retesting, and drive priority defects to timely closure.
Assess test evidence, residual risks and entry/exit criteria; provide clear quality status and an evidence-based release-readiness recommendation to stakeholders.
Coordinate test environments, dependencies and data needs across development, business analysis, operations, release, vendor and partner teams.

Risk Accountabilities

Apply enterprise quality engineering frameworks, software delivery controls, security requirements and regulatory expectations within assigned scope.
Maintain traceability from requirements to test cases, automated tests, execution results, defects and readiness evidence.
Identify, document, manage and escalate quality, operational, data, environment and implementation risks, including non-standard or high-risk activities.
Use quality metrics and trend analysis to evaluate coverage, defect health, automation effectiveness and release readiness; communicate concise, decision-oriented reporting.
Conduct reviews of test strategies, scenarios, scripts and evidence to confirm completeness, reusability, maintainability and compliance.
Protect customer and Bank information by following access, test-data masking, segregation-of-duties and evidence-retention requirements.
Improve delivery efficiency by eliminating redundant testing, increasing automation, strengthening reusable assets and addressing recurring defect patterns.
Support implementation validation and post-implementation checks to confirm processing integrity and production stability.

Team Accountabilities

Work as a collaborative member and quality advocate within the assigned delivery team, communicating progress, decisions, risks and issues promptly.
Provide technical direction within assigned scope and coach junior or intermediate quality engineers on mainframe testing, automation, defect analysis and engineering practices.
Partner effectively with software engineers, business systems analysts, product, operations, release teams and external partners to resolve issues and achieve quality outcomes.
Share reusable test assets, lessons learned and mainframe domain knowledge; contribute actively to communities of practice and continuous improvement.
Work autonomously on complex testing and analysis while knowing when to escalate cross-team, high-risk or unresolved concerns.
Contribute to a fair, positive, inclusive and high-performing environment that promotes quality, innovation, teamwork and continuous learning.
Act as a brand ambassador for the business area and the Bank, internally and externally.
Advanced knowledge of quality engineering principles, the software testing life cycle, Agile delivery and risk-based testing.
Hands-on mainframe testing experience with z/OS, TSO/ISPF, JCL, COBOL, DB2 and batch processing; experience with IMS, VSAM and sequential files is strongly preferred.
Ability to understand mainframe program flow, copybooks, file layouts, job dependencies, database updates and interfaces sufficiently to design effective tests and diagnose failures.
Advanced SQL and data-validation skills, including joins, reconciliation and verification of inserts, updates, extracts and downstream outputs.
Strong debugging and problem-solving skills, including job-log, spool, return-code and abend analysis, with clear evidence provided to development teams.
Demonstrated ability to perform complex testing autonomously and lead quality delivery across one product line or multiple delivery teams within assigned scope.
Strong experience building or maintaining automated tests and applying source control, DevOps, service virtualization, test-data management and CI/CD/continuous testing practices.
Ability to define measurable coverage, quality metrics, exit criteria and release-readiness recommendations.
Strong written and verbal communication, stakeholder management, planning and prioritization skills.
Future-focused approach that identifies delivery gaps, recurring risks and practical opportunities to improve quality, speed and reliability.
Reports to a Quality Engineering Practice Lead or designated people leader.

Experience and Education

Undergraduate degree or technical certificate in Computer Science, Engineering or a related discipline, or equivalent practical experience.
Typically 5–7 years of relevant quality engineering or software testing experience, including substantial hands-on mainframe application testing.
Demonstrated experience owning test strategy and delivery for medium-to-high-complexity initiatives.
Experience in financial services, payment or credit-card processing, or another high-volume regulated environment is an asset.
Experience with API or distributed-channel testing and modern mainframe automation tooling is an asset.
