• Collaborate with engineers on RSpec integration and unit test coverage — reviewing test quality, identifying gaps, and contributing tests where needed
• Define and enforce quality gates in the CI/CD pipeline: test pass thresholds, coverage floors, Brakeman/bundler-audit clean runs, and ESLint/RuboCop compliance
• Develop and maintain test data strategies using synthetic data exclusively — patient names with -SYN suffix, IDs with SYNTHETIC_ prefix — ensuring no PHI enters any test artifact
• Validate data mapping correctness across dental practice management systems (DPMS): Orthotrac, PracticeWorks, SoftDent, WinOMS, and others
• Write and maintain VCR cassettes and WebMock stubs for external HTTP integrations, ensuring tests remain deterministic and do not call live services
• Review and triage Brakeman security findings, coordinating remediation with engineers before PRs are merged
• Perform exploratory testing against staging environments, filing clear, reproducible bug reports with steps, environment context, and expected vs. actual behavior
• Maintain and evolve the QA section of the AI Code Review Checklist as the team's practices mature
• Participate in pull request reviews with a quality and compliance lens: PHI exposure, OWASP Top 10 risks, hardcoded secrets, overly broad rescue blocks, invalid dependencies
• Collaborate with frontend-focused engineers to ensure React components and TanStack Query state management are covered by meaningful tests
• Contribute to and validate API contract tests as the Rails API evolves
• Participate in AI-augmented development workflows, reviewing AI-generated tests for correctness, hallucinated mocks, and phantom assertions
• Proactively update test documentation, coverage reports, and QA runbooks when behavior or architecture changes

• Participate in AI-augmented development workflows, reviewing and validating AI-generated code against acceptance criteria.
• Follow Git best practices: feature branches, pull requests for all changes, and clear commit hygiene; proactively update documentation when behavior or architecture changes.
• Design, build, and maintain Windows workflows using C++ and MFC.
• Debug and remediate defects across UI, threading, memory/resource management, and performance hotspots.
• Modernize and refactor legacy areas to improve maintainability, testability, and stability while preserving user workflows.

• Implement secure authentication/authorization patterns appropriate for enterprise and regulated contexts.
• Create and maintain automated checks and diagnostics to support supportability and observability.
• Design and evolve MS SQL schemas with emphasis on clarity, performance, and data integrity.
• Write and optimize queries, stored procedures, and migration scripts where appropriate.
• Collaborate with QA and Engineering to validate data correctness and enable reliable test data setup.
• Contribute to troubleshooting production issues through data analysis and root cause investigation.
• Demonstrate knowledge of QA processes in an Agile environment, including acceptance criteria, defect triage, regression awareness, and collaboration with QA roles.
• Contribute to test strategy (unit/integration as appropriate), and ensure features meet functional, security, and reliability expectations.
• Maintain a disciplined approach to compliance and secure engineering practices.
