Senior SQA Engineer (LLM) Remote Pakistan

• Design and own the end-to-end QA strategy for the Conversational Banking Platform, covering functional, regression, performance, security, and AI-specific evaluation.
• Build and maintain golden datasets, eval suites, and LLM-as-judge frameworks to validate conversational quality across intents, languages, and tenants.
• Define the tenant onboarding QA gate, the certification checklist every new business unit must pass before going live.
• Establish regression strategies for prompt changes, model upgrades, retrieval index updates, and guardrail policy changes.
• Use Langfuse traces to drive evaluation: mine production failures, convert them into test cases, and close the loop with engineering.
• Test NeMo Guardrails configurations against jailbreaks, prompt injection, off-topic drift, and false-positive over-blocking.
• Validate governance and compliance behaviors: data residency, PII handling, regulated-product disclosures, and off-limits topics.
• Build automated test harnesses for Spring AI services, including tool-calling validation, RAG groundedness, and integration with Cosmos DB and MongoDB data layers.
• Partner with the Platform team on quality metrics, SLOs, and the platform eval scorecard.
• Coach feature engineers and tenant teams on writing their own evals, making platform-grade quality self-service over time.

Tech Stack To Work

• AI/Application: Spring AI, Java/Spring Boot
• Data: Cosmos DB (vector and operational), MongoDB
• Observability and evaluation: Langfuse
• Governance and safety: NVIDIA NeMo Guardrails
• CI/CD: standard enterprise pipelines with automated quality gates

Required Experience and Skills

• 6+ years in software QA, with at least 1–2 years testing LLM-based, RAG, or conversational AI systems in production.
• Hands-on experience with LLM observability and evaluation tools such as Langfuse, LangSmith, Arize, or Phoenix.
• Working knowledge of eval frameworks such as Ragas, DeepEval, Promptfoo, or TruLens — including metrics like faithfulness, groundedness, answer relevance, and context precision.
• Practical understanding of how to test non-deterministic systems: golden datasets, semantic similarity, LLM-as-judge, and statistical regression detection.
• Experience testing guardrail or policy frameworks (NeMo Guardrails, Guardrails AI, or similar).
• Solid foundation in API testing, automation frameworks (e.g., pytest, JUnit, Karate, RestAssured), and CI/CD integration.
• Familiarity with Spring and Spring Boot applications and JVM-based services.
• Comfortable writing queries against NoSQL stores (MongoDB, Cosmos DB) for test data setup and trace inspection.
• Strong written communication : able to produce clear test plans, defect reports, and tenant readiness assessments.

Good to Have

• Experience in banking, financial services, or another regulated industry.
• Exposure to multi-tenant platforms: understanding how shared infrastructure changes the testing problem.
• Familiarity with red-teaming, adversarial prompt testing, and prompt injection defense.
• Working knowledge of vector databases, embedding models, and retrieval evaluation.
• Experience with multi-language conversational systems.
• Performance and load testing experience for AI workloads (token throughput, latency percentiles, cost per conversation).
• Contributions to open-source eval or AI testing tooling.
• Experience working with compliance, risk, or audit teams on AI assurance.
