We are seeking an AI QA Engineer with specialization in LLM/NLP model quality assurance to ensure our language models and NLP applications meet the highest standards of accuracy, reliability, and safety. In this role, you will develop rigorous testing strategies for our AI models — including large language models — and lead efforts to detect issues such as factual errors, biases, and instability in model outputs. You will work closely with data scientists and engineers to integrate testing into the model development lifecycle, from early prototyping to post-deployment monitoring. This position is ideal for someone with a strong quality assurance background and a passion for AI, who can bridge the gap between traditional software QA and the unique challenges of evaluating AI systems (chatbots, NLP APIs, etc.) in the context of our Ukrainian LLM project and other products.

What you will do

• Develop and execute comprehensive AI model evaluation strategies to assess the performance of our NLP and LLM systems. Define testing methodologies that cover correctness (e.g., accuracy of responses, compliance with requirements), consistency, and fairness of model outputs.
• Analyze benchmarking datasets, define gaps, and develop the first SOTA benchmarking framework for the Ukrainian language.
• Analyze training datasets and collaborate with data engineers on processing pipelines improvement. Implement a training data testing framework.
• Implement both automated and manual testing for applications powered by large language models. This includes creating automation scripts or test harnesses that can systematically query models with test cases (prompts/questions) and verify responses, as well as performing hands-on review of outputs for subjective evaluation.
• Build and curate high-quality test datasets for model evaluation. Manage a repository of test inputs (e.g., sample user queries, edge-case scenarios, conversational dialogues) along with expected or reference outputs when applicable. Ensure these datasets are diverse, balanced, and representative of real-world use cases, including Ukrainian language content and culturally relevant scenarios.
• Develop pipelines for synthetic data generation and adversarial example creation to challenge the model’s robustness. Use techniques such as paraphrasing, noise injection, or adversarial prompting to produce test cases that can reveal model weaknesses.
• Design and maintain testing frameworks to detect hallucinations, biases, and other failure modes in LLM outputs.
• Define and track key AI performance metrics. Monitor metrics like factual accuracy, coherence/fluency, relevancy to prompt, response diversity, latency of response, and user satisfaction ratings if available. Establish baseline metrics for each new model version and ensure subsequent iterations meet or exceed these benchmarks.
• Work closely with the AI development team to integrate QA in the development process. Collaborate with data scientists to test models at early stages (e.g., evaluating prototypes before full deployment), and with ML engineers to include automated tests in CI/CD pipelines for model updates.
• Debug and analyze AI model failures. When tests uncover issues (e.g., a model consistently gives incorrect information in a certain domain or shows a bias), investigate and identify root causes by analyzing model outputs and underlying data. Provide clear, detailed reports on issues with steps to reproduce and potential causes.
• Provide feedback and recommendations for model improvement. Work with prompt engineers or NLP scientists to refine prompts and instructions that guide the model towards better performance.
• Implement continuous monitoring in production to catch regressions or new issues. Set up mechanisms to regularly evaluate live model outputs (via sampling or user feedback analysis) and alert the team if any quality metrics degrade over time (indicative of model drift or unforeseen use cases).
• Maintain comprehensive test documentation and reports. Document test plans, test case suites, and summarize the results of evaluations for each model version (including graphs/metrics and qualitative findings). Communicate findings to both technical teams and stakeholders in a clear, actionable manner.

Qualifications and experience needed

Are you ready to design and deploy AI systems that run at truly massive scale?

We are hiring an MLOps Engineer specializing in Large Language Model (LLM) infrastructure to design and maintain the robust platform on which our AI models are developed, deployed, and monitored. As an MLOps Engineer, you will build the backbone of our machine learning operations — from scalable training pipelines to reliable deployment systems — ensuring that our NLP models (including LLMs) can be trained on large datasets and served to end-users efficiently. This role sits at the intersection of software engineering, DevOps, and machine learning, and is crucial for accelerating our R&D in the Ukrainian LLM project. You’ll work closely with data scientists and software engineers to implement best-in-class infrastructure and workflows for the continuous delivery of AI innovations.

What you will do

• Design and implement modern, scalable ML infrastructure (cloud-native or on-premises) to support both experimentation and production deployment of NLP/LLM models. This includes setting up systems for distributed model training (leveraging GPUs or TPUs across multiple nodes) and high-throughput model serving (APIs, microservices).
• Develop end-to-end pipelines for model training, validation, and deployment. Automate the ML workflow from data ingestion and feature processing to model training and evaluation, using technologies like Docker and CI/CD pipelines to ensure reproducibility and reliability.
• Collaborate with Data Scientists and ML Engineers to design MLOps solutions that meet model performance and latency requirements. Architect deployment patterns (batch, real-time, streaming inference) are appropriate for various use-cases (e.g., a real-time chatbot vs. offline analysis).
• Implement and uphold best practices in MLOps, including automated testing of ML code, continuous integration/continuous deployment for model updates, and rigorous version control for code, data, and model artifacts. Ensure every model and dataset is properly versioned and reproducible.
• Set up monitoring and alerting for deployed models and data pipelines. Use tools to track model performance (latency, throughput) and accuracy drift in production. Implement logging and observability frameworks to quickly detect anomalies or degradations in model outputs.
• Manage and optimize our Kubernetes-based deployment environments. Containerize ML services and use orchestration (Kubernetes, Docker Swarm or similar) to scale model serving infrastructure. Handle cluster provisioning, health, and upgrades, possibly using Helm charts for managing LLM services.
• Maintain infrastructure-as-code (e.g., Terraform, Ansible) for provisioning cloud resources and ML infrastructure, enabling reproducible and auditable changes to the environment. Ensure our infrastructure is scalable, cost-effective, and secure.
• Perform code reviews and guide other engineers (both MLOps and ML developers) on building efficient and maintainable pipelines. Troubleshoot issues across the ML lifecycle, from data processing bottlenecks to model deployment failures, and continuously improve system robustness.
