• Work with software developers to investigate issues.
• Maintain testing records and evidence.
• Prepare testing completion reports.

• Internal Administration Platform — operations, customer support and transaction management

Key Performance Expectations

Performance can be assessed based on test coverage, defect detection before production, quality of test documentation, regression-test effectiveness, accuracy of transaction/database validation, turnaround time for testing, and the number/severity of production defects attributable to inadequate testing .

For AntBank, I would keep the official title simply “Software Tester” while making the job description strongly focused on financial software, card issuance, wallet, API and database testing . That gives you a broad enough employment title while making the genuine business need for the position very clear.
