Job Description

Ciklum is looking for a Senior Manual QA Engineer (AI / LLM & API Testing) to join our team full-time in India.

We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About the role:

As a Senior Manual QA Engineer (AI / LLM & API Testing), become a part of a cross-functional development team engineering experiences of tomorrow.

Client is looking for a QA Engineer to test an AI-powered knowledge management and retrieval platform. The solution includes document processing, RAG-based search, LLM-generated answers and integrations with external systems. An optimal candidate should be able to test traditional software features and AI-specific behavior (e.g. hallucination detection, referencing sources, confidence scores, PII handling).

Responsibilities:

• E2E testing of multi-format document processing (PDFs, Word, PPT, images/screenshots) and parsing accuracy (OCR/Vision extraction)
• Performing standard test activities: acceptance criteria refinement, test scenario creation, execution, reporting, defect management, and regression testing
• Validation of RAG retrieval quality, including hybrid search (semantic + BM25 keyword search), metadata filtering, and retrieval scoping
• Verification of probabilistic AI outputs for answer grounding, hallucination risk, source references, and confidence scores
• E2E testing of human-in-the-loop content workflows (AI draft generation, confidence score thresholds, reviewer approvals, and vector DB publishing sync)
• API and enterprise integration testing (portals, chatbots, ticketing systems) across deterministic and non-deterministic flows
• Validation of data protection controls, including PII scanning and redaction
• Support QA automation at both API and UI levels for critical data pipelines

Requirements:

• Strong foundation in software QA processes
• Hands-on experience with web application testing and REST API testing (manual and automated)
• Practical understanding of testing both deterministic logic (pass/fail, APIs, DB sync) and probabilistic AI behavior (LLM outputs, context edge cases)
• Ability to evaluate RAG architecture outputs
• Experience verifying document processing pipelines (data extraction, OCR, parsers)
• Solid understanding of data privacy principles in AI applications
• Working knowledge of SQL
• Experience working with Azure-based systems is a strong plus
• Experience with Boost.ai
• Experience testing enterprise integrations (CRMs, SAP, SharePoint, Jira)
• Experience with UI automated testing

What’s in it for you?

• Strong community: Work alongside top professionals in a friendly, open-door environment
• Growth focus: Take on large-scale projects with a global impact and expand your expertise
• Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
• Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies
• Care: We’ve got you covered with company-paid medical insurance, mental health support, and financial & legal consultations
