QA Engineer
Ensures software quality through manual and automated testing, catching bugs before production and fostering a quality culture.
What does a QA Engineer do?
- Designs test plans from requirements, prioritizing by risk and business impact
- Runs regression cycles and exploratory testing to uncover what the happy path hides
- Documents bugs with reproduction steps, evidence, and severity that speed up fixes
- Defines acceptance criteria with product and development before code is written
- Verifies fixes and coordinates acceptance testing with users when appropriate
- Reports each release's quality status with data that supports the go/no-go decision
Ideal OCEAN+ Profile
Focused individual work with moderate interaction through bug reports and team reviews
Effective collaboration with developers when reporting bugs without triggering defensiveness
Resilience under deadline pressure that pushes toward cutting test coverage
Follows structured test plans, regression suites, and quality checklists with process discipline; quality requires defined rhythm and method
Strengths and Red Flags
Strengths
- Adversarial thinking that anticipates failures before they reach production
- Systematic test case design with edge-case coverage
- Regression automation that speeds up delivery cycles without sacrificing quality
- Precise bug documentation that shortens the resolution cycle
Red Flags
- Limiting testing to happy-path cases without exploring error paths and edge cases
- Blocking releases over minor bugs without assessing real impact
- Resistance to automating repetitive tests due to attachment to manual process
- Difficulty communicating the business impact of found bugs

Tests the system as a rushed, distracted, or malicious user, not just the user described in the manual
OpennessThe profile's Openness envisions usage paths the design never anticipated
Logs even minor bugs they decide not to report formally, along with their reasoning
ConscientiousnessVery high Conscientiousness leaves full traceability of the judgment applied in each cycle
Frames every bug as a product problem rather than a developer's mistake
AgreeablenessMedium-high Agreeableness preserves collaboration with development even when delivering bad news
Holds their risk assessment even when the whole team wants to launch and the data says no
Emotional StabilityEmotional Stability lets them be the last line of defense without caving to group pressure
Requirements and Skills
- Experience in functional testing of web or mobile applications
- Proficiency with test case management and bug tracking tools
- Basic knowledge of SQL and APIs to verify data behind the interface
- Understanding of the agile development cycle and the role of quality at each stage
- Recognized testing certifications such as ISTQB are valued though not required
