Job summary

Appnovation is seeking a QA / AI Evaluation Engineer to join a forward-leaning team. You will run large-scale evaluations, measure factual grounding and accuracy lift, and build a metrics framework to show quality improvements over time.

You will design tests, automate regressive suites, and collaborate with engineering to reproduce fixes. Strong Python, data-science skills, and experience with LLM evaluation are essential.

Qualifications

• 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.
