About the role
AI Test Engineering is a hands-on role within VLabs Quality Engineering, responsible for validating the performance, reliability, and integrity of AI-enabled solutions in production environments.
This role operates at the intersection of AI engineering and quality assurance, ensuring that outputs from LLMs, OCR pipelines, document classification models, and agentic workflows perform as expected at scale and meet defined business performance thresholds.
Working closely with the Programme Test Manager and partnering with engineering, product, and delivery teams, this role translates AI testing strategy into executable frameworks, evaluation pipelines, and reusable assets embedded into the delivery lifecycle.
Key responsibilities
AI evaluation & test design3 items
- Translate AI testing strategy into executable test scenarios across LLM outputs, document classification, extraction accuracy, agent workflows, and edge cases
- Design adversarial and boundary test inputs to expose hallucination, misclassification, and failure modes
- Validate AI outputs for structure, consistency, accuracy, and production readiness against defined performance thresholds
Evaluation engineering & automation4 items
- Build reusable Python-based evaluation frameworks, including output validation, hallucination detection, and scoring mechanisms
- Develop parameterized test scripts reusable across features, models, and releases
- Implement AI-as-Judge frameworks, including prompt design, scoring logic, and calibration of evaluation reliability
- Embed evaluation frameworks into CI/CD pipelines to support continuous testing and deployment
Drift detection & quality monitoring3 items
- Design and operate drift detection frameworks using fixed baseline datasets and scheduled re-evaluation
- Establish thresholds to distinguish acceptable variation from performance degradation
- Enable release gating by identifying regressions prior to production deployment
Ground truth & data quality3 items
- Build and maintain ground truth datasets in partnership with subject matter experts
- Define standards for classification, extraction accuracy, and acceptable output characteristics
- Continuously update datasets to reflect evolving business requirements and use cases
Workflow & integration testing4 items
- Test end-to-end agentic workflows, validating data integrity, error propagation, and fallback behavior
- Perform API-level testing of AI pipeline endpoints using Python and Postman/Newman
- Validate data persistence and integrity across system layers using SQL
- Partner with engineering teams to ensure testability, observability, and system reliability
Standardization & scaling2 items
- Define and scale standardized AI evaluation patterns and reusable quality frameworks across VLabs
- Contribute to enterprise AI quality standards and reference architectures
Governance & Responsible AI2 items
- Ensure adherence to Responsible AI, data privacy, and governance requirements
- Support auditability, traceability, and transparency of AI outputs and evaluation processes
Stakeholder enablement3 items
- Translate evaluation results into actionable insights for engineering, product, and business stakeholders
- Support decision-making on model readiness, release risk, and performance trade-offs
- Proactively identify risks, patterns, and systemic issues and escalate appropriately
Who we are looking for
Success requires independent execution, strong technical depth, and the ability to proactively identify risks, patterns, and performance gaps while enabling rapid, production-grade deployment of AI capabilities.
