What You’ll Be Doing

• Quality & AI-First Mindset
• Evolve a modern, AI-first quality strategy for our fast-scaling SaaS architecture, including foundational infrastructure and emerging agentic/intelligent systems.
• Integrate AI enhancements into CI/CD pipelines (e.g., predictive flakiness detection, automated test generation, self-healing scripts) to improve isolation, data setup, & execution reliability using existing/suggesting tools.
• Establish scalable testing practices that support hyper-growth and petabyte-scale AI data pipelines.

• AI-Focused Test Strategy, Automation & Evaluation
• Design deterministic and statistical testing approaches for non-deterministic LLM-based and agentic systems, addressing hallucinations, prompt injection, bias, drift, and safety risks.
• Build automated evaluation pipelines and harnesses for correctness, faithfulness, retrieval quality, generation accuracy, tool-calling, planning sequences, and multi-agent flows.
• Execute/Develop test frameworks for the full AI lifecycle: prompts, datasets, embeddings, model versions, RAG pipelines (end-to-end validation), and guardrails.
• Implement red-teaming, bias/fairness checks, and compliance mechanisms; leverage in trend frameworks for metrics and observability.
• Integrate AI-specific quality signals into CI/CD for automated gating and continuous monitoring.

• Cross-Functional & End-to-End Testing
• Partner closely with product, data science, AI engineering, and dev teams to test AI features, conduct multi-agent simulations, and ensure high-quality roadmap delivery.

• Facilitate knowledge sharing and upskilling on AI testing best practices across the Quality Function.

• Metrics, Observability & Continuous Improvement
• Drive core metrics (DORA, test coverage/effectiveness) plus AI-specific indicators (e.g., hallucination rate, context precision, drift detection).
• Build real-time dashboards and support A/B testing of models with post-deployment monitoring.

• Culture, Mentorship & Innovation
• Champion a quality-first, ethical AI mindset organization-wide.
• Mentor SDET’s, lead workshops on AI risks/validation, and influence design/deploy/incident processes.
• As a foundational hire, define roadmaps and best practices for sustainable AI quality assurance.

Challenges You'll Tackle

• Ensuring reliability in agentic systems amid data drift and non-deterministic behavior.
• Scaling tests for global SaaS while maintaining low hallucination rates and strong safety guardrails.
• Building evaluation from scratch in a rapidly evolving landscape (e.g., multi-modal, agentic flows).

Success in the First 6 Months

• Launch foundational AI test frameworks and pipelines, achieving 80-90% coverage for key AI components.
• Reduce AI-related defect escapes by 30-40% and integrate automated safety/compliance checks into all releases.
• Establish metrics dashboards and evaluation loops that enable data-driven iteration on intelligent features.

What You Will Bring

• 7+ years in Quality Engineering/SDET roles within cloud-native SaaS environments, including 2+ years hands-on with AI/ML/LLM systems.
• Expertise in automated testing infrastructure, CI/CD (Jenkins/GitHub Actions), and test pyramid strategies (unit → E2E).

• Strong full-stack testing experience (frontend/backend/API) and collaboration with dev teams.
• Proven experience testing LLMs, AI agents, RAG pipelines, and related risks (hallucinations, prompt injection, bias, drift).
• Proficiency in JS/TS, working knowledge of Python or Java; experiance with AI evaluation frameworks (e.g., Ragas, DeepEval, LangChain/LangSmith/LangFuse) and other tools you may have proficiency in.
• Knowledge of performance, Stress and Load testing tools like K6, JMeter, Blazemeter will be nice to have.
• Knowledge of observability (NewRelic), statistical testing methods, red-teaming, and ethical AI practices.
• Excellent communication, and coaching skills; ability to thrive in ambiguity and drive innovation.
• Bachelor's/Master's in Computer Science, AI, or related; certifications (e.g., ISTQB AI Testing) a plus.
• Strong English language communication and collaboration skills

We value adaptability in this fast-moving field—equivalent experience and a strong portfolio (e.g., open-source contributions, case studies) are highly regarded.
