The AI Quality Engineer roadmap
Each topic below carries a study note, real reading, and practice questions in the app. A topic unlocks when you pass the one before it, so the order is the path, so you are never guessing what to learn next.
Phase 1AI quality engineering foundations
QA for AI
Testing an AI feature is not testing a deterministic function.
Testing nondeterministic systems
Model outputs vary run to run.
Test strategy
You cannot test everything.
Phase 2AI quality engineering test design
Behavioral tests
Instead of one fuzzy 'is it good' check, decompose behavior into capability-isolating tests (faithfulness, coverage, length, negation) so a failure points to the specific broken behavior.
Edge cases
Systems break at the boundaries of the input space: empty and oversized inputs, non-English and mixed scripts, noisy OCR and tables, and questions whose answer is absent.
Adversarial tests
Adversarial suites parametrize attack techniques (role-play, encoding, injection via retrieved content, multi-turn escalation) and measure a leak rate, using known-resisted strings only as a…
Phase 3AI quality engineering automation
Eval suites
Automate evaluation by pairing cheap deterministic property checks with a rubric-based LLM judge that is itself validated against human labels.
Regression gates in CI
Eval scores are noisy, so a naive 'no dip' gate blocks neutral PRs and trains the team to bypass it.
Reproducibility
An eval result you cannot reproduce cannot be trusted.
Phase 4AI quality engineering signals
Metrics
Pick metrics that reveal the failures that matter.
Failure analysis
A pile of failing cases becomes signal only when clustered by root cause and sized by frequency and severity.
Monitoring in production
Offline evals cannot see live distribution shift.
Phase 5AI quality engineering release
Release gates
A go/no-go gate uses pre-agreed multi-dimensional criteria (helpfulness, safety, faithfulness, no regression on critical scenarios) where any safety-critical failure blocks regardless of average…
Red-teaming
Structured red-teaming works from a harm taxonomy with planned coverage across categories and attacker personas, logs every attempt, and reports per-category success rates and severity.
Incident response
When a promoted model produces unsafe answers, mitigate first: roll back to the last known-good version to stop user harm, then preserve the offending samples, root-cause the regression, and add a…

Coming from another job?
Most people on this path arrived from somewhere else: engineering, analysis, testing, product, support, compliance, design. Onboarding asks what you do today and builds a short starter run out of the gaps, so you begin from what you already know rather than from chapter one. See how it works.
