KEY ROLE & RESPONSIBILITIES

Generative AI & LLM Evaluation

- Build automated testing suites to detect hallucinations, bias, toxicity, and prompt injection vulnerabilities across LLM-powered products

- Implement automated evaluations for RAG systems measuring context relevance, groundedness, and answer faithfulness using frameworks like RAGAS or DeepEval

- Design test beds to validate multi-agent workflows — tool-calling accuracy, multi-step reasoning, memory, and autonomous decision loops

- Build and run automated conversation simulations — scripted and synthetic user journeys — to stress-test agent behaviour across intents, edge cases, and multi-turn dialog flows

- Create prompt regression frameworks to assess how changes in system prompts, temperature, and sampling parameters impact output consistency

Data Quality Assurance

- Statistically validate AI data outputs — distributions, precision/recall, error pattern analysis — to catch silent data quality failures before production

- Programmatically audit data ingestion, transformation, and feature store pipelines for schema drift and data corruption

- Validate vector DB indexing, embedding semantic similarity accuracy, and retrieval latency

- Verify quality, diversity, and privacy compliance of synthetic datasets used for model training and evaluation

Classical ML & Deep Learning Validation

- Maintain automated suites tracking ML metrics — Precision, Recall, F1, ROC-AUC — and deep learning loss curves across model versions

- Implement continuous monitoring scripts to detect data and concept drift on live inference endpoints

Automation Engineering & CI/CD

- Build and maintain scalable test automation frameworks for APIs, backend services, and model endpoints

- Embed AI evaluation and data QA suites into MLOps and CI/CD pipelines so quality failures block releases automatically

- Define and track AI quality KPIs and communicate release readiness to engineering and product teams

- Infrastructure as Code — Docker, Kubernetes, Terraform for managing containerised test environments at scale

- UI Automation — Playwright or Cypress for end-to-end conversational AI application testing

- Performance Engineering — Locust or JMeter for load testing heavy AI inference endpoints under peak traffic

- Statistical Hypothesis Testing — t-tests, confidence intervals, significance testing to distinguish real quality signal from noise

- Synthetic Data Generation — using LLMs to generate diverse test cases and evaluation datasets at scale

PERKS & BENEFITS

- Opportunity to work with some of the smartest minds to solve complex challenges at scale.

- Impactful role in shaping and securing a global, cloud-native & AI driven platform.

- Innovative, collaborative, and fast-paced culture
