Job summary

Appnovation Technologies in Toronto is seeking a QA / AI Evaluation Engineer to join a forward-leaning team that delivers high-quality AI-assisted solutions.

You will run evaluations at scale across large question sets, measure factual grounding and accuracy lift, and build the metrics framework that shows incremental improvement. You will design load tests and automate evaluation pipelines within CI/CD, collaborating with engineering and data science to reproduce and verify fixes.

Qualifications

• Bachelor’s Degree in a technical field or equivalent experience.
• 4+ years in QA / test engineering, with exposure to data/ML systems.
• Strong Python and data-science techniques for measuring factual grounding and answer quality.
• Experience with LLM evaluation frameworks and statistical analysis.
• Ability to build automated, large-scale eval harnesses plus lighter human-in-the-loop A/B tests.
• Comfort working across multiple LLM providers’ outputs.
• Test automation frameworks and scripting.
• Detail-oriented, with strong analytical and communication skills.

Responsibilities

• Run evals at scale across large question sets, from small human-UAT batches up to hundreds of thousands or millions of automated evaluations.
• Statistically measure factual grounding and accuracy lift (before/after), not just human A/B testing.
• Build a metrics framework showing quality improvement (e.g., "answer is X% supported by source content / Y% better").
• Design load and quality tests as the corpus scales.
• Define and maintain test plans, test cases, and quality gates.
• Automate regression and evaluation suites; integrate them into CI/CD.
• Report quality metrics clearly to technical and non-technical stakeholders.
• Collaborate with engineering to reproduce, triage, and verify fixes.
• Continuously improve QA processes and coverage.
