Automation QA Engineer

Ciklum is looking for a Automation QA Engineer to join our team full-time in Poland.

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 Automation QA Engineer, become a part of a cross-functional development team engineering experiences of tomorrow.

The Project: We are partnering with B&R Industrial Automation to significantly upgrade the Retrieval-Augmented Generation (RAG) architecture of their AS client's system. Our goal is to drastically reduce AI hallucinations in code generation and optimize retrieval latency without re-architecting their existing platform.

Responsibilities:

• Own the evaluation lifecycle, offline acceptance testing, and KPI measurement for the AS client's RAG pipeline
• Lead the co-creation and management of the project's "golden dataset" to consistently benchmark AI performance
• Implement and manage the RAGAS evaluation harness and automated CI/CD regression testing
• Track, classify, and build root-cause taxonomies for LLM hallucinations, with a specialized focus on code-generation correctness
• Golden Dataset & Baselines: Collaborate with client domain experts and technical leads to build a robust synthetic test set (~90+ queries across multiple categories) and establish baseline metrics for Faithfulness, Context Precision, and Answer Relevance
• Evaluation Harness: Build and automate evaluation pipelines using RAGAS and custom Python scripts, enabling A/B comparisons between the baseline, MVP, and full implementation
• Regression & CI/CD Guardrails: Implement automated CI/CD regression checks within Azure DevOps, ensuring that a >5% drop in core metrics automatically blocks pipeline deployments
• Hallucination Tracking: Develop a root-cause taxonomy for hallucinations and track code-generation queries separately to ensure the AI generates functionally correct and compilable output
• Performance Benchmarking: Measure and monitor pipeline latency, rigorously validating P95 latency targets (sub-4.5s) under representative concurrent load

Requirements:

• Background: Mid-to-Senior level experience in Data Science, Machine Learning Evaluation, AI Quality Assurance, or Data Engineering
• Evaluation Frameworks: Deep, hands-on experience with LLM evaluation frameworks (e.g., RAGAS, DeepEval, TruLens) and establishing human-anchored or synthetic benchmarks
• Technical Stack: Strong proficiency in Python. Solid experience with CI/CD tools (especially Azure DevOps) and integrating complex test suites into automated deployment pipelines
• Data & Observability: Experience working with databases (PostgreSQL) and integrating custom telemetry or observability data (e.g., Azure App Insights) into evaluation reports
• Analytical Mindset: Strong attention to detail with the ability to perform rigorous error analysis, build structured taxonomies for failures, and identify embedding drift

Personal skills:

• Highly collaborative and data-driven; comfortable working directly with client SMEs to validate queries and presenting evaluation scorecards to guide engineering decisions

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
• Flexibility: Enjoy flexibility – full remote working possibilities
• Care: We’ve got you covered with company-paid medical insurance, mental health support, and financial & legal consultations
