The position requires 5+ years in software quality engineering, strong API/test automation skills, and experience integrating tests into CI/CD pipelines.

Qualifications

• 5+ years of software quality engineering, SDET, test automation, or related software engineering experience.
• Strong experience designing, building, and maintaining automated test frameworks for APIs, backend services, and integration workflows.
• Hands-on programming or scripting experience with one or more modern languages such as TypeScript, JavaScript, Java, C#, Python, or similar.
• Experience integrating automated testing into CI/CD pipelines using tools such as Azure DevOps, GitHub Actions, GitLab CI, Jenkins, or comparable platforms.
• Strong understanding of REST APIs, JSON, HTTP, authentication and authorization patterns, service dependencies, and distributed systems.
• Experience with automated regression testing, smoke testing, integration testing, contract testing, and release validation.
• Practical experience with test data management, environment readiness, defect triage, and root-cause analysis.
• Ability to collaborate effectively with technical and non-technical stakeholders and communicate quality risks clearly.
• Strong analytical, troubleshooting, and systems-thinking skills.

Responsibilities

• Design, build, and maintain reusable API, integration, regression, smoke, contract, and end-to-end test automation frameworks for FinTech Connect, Nexus, and Tallied.
• Define and implement CI/CD quality gates for pull requests, merges, release candidates, and production readiness.
• Create formal test plans for major releases, partner integrations, regulatory-impacting workflows, and credit card application changes.
• Develop automated tests for REST APIs, backend services, integration workflows, data validation, authorization logic, account servicing, transaction flows, and partner-facing interfaces.
• Establish contract testing, mocking, stubbing, and service virtualization practices for external providers, partner integrations, and dependent systems.
• Implement load, performance, resiliency, negative-path, and failure-mode testing for high-volume API and credit card workflows.
• Use AI-assisted tooling to generate test scenarios, expand edge-case coverage, accelerate regression suite creation, and identify gaps in requirements or acceptance criteria.
• Use AI-assisted analysis to validate automated test results, summarize failures, detect anomalies, and distinguish product defects from test data, environment, dependency, or automation issues.
• Build release-readiness dashboards and quality metrics covering regression health, defect trends, coverage, performance, test reliability, and release risk.
• Partner with developers, product owners, DevOps engineers, and architects to define testable requirements, improve observability, and shift quality practices earlier in the delivery lifecycle.
• Support after-hours post-release smoke testing for critical production workflows when needed.
• Mentor QA engineers, software engineers, and delivery teams on automation standards, testability, AI-enabled quality practices, and quality-first engineering habits.
