• Develop AI‑driven features for document understanding, summarization, entity extraction, validation, and workflow automation.
• Work with Vertex AI & Gemini models for experimentation, fine‑tuning, evaluation, and deployment.
• Create and maintain LLM-as-a-judge evaluation setups to measure model quality, reliability, and accuracy.
• Optimize costs, latency, and performance of model inference and orchestration.
• Collaborate with software engineers to integrate AI components into microservices and APIs.
• Build robust monitoring, observability, and guardrails for LLM behavior, hallucination mitigation, and data safety.
• Work with stakeholders to understand business needs and translate them into feasible GenAI solutions.
• Document designs, experiment results, prompts, evaluation metrics, and best practices.
• Stay current with the rapidly evolving GenAI ecosystem and provide strategic recommendations.

Requirements:

• 4+ years of experience in applied Machine Learning, GenAI engineering, or NLP/LLM‑focused roles.
• Hands‑on experience with Google Cloud Platform (GCP).
• Strong experience working with LLMs (OpenAI, Gemini, Claude, Llama, Mistral, etc.) .
• Practical knowledge of:
• RAG architectures (vector stores, embeddings, retrieval patterns)
• LLM-as-a-judge evaluation and AI metrics
• Guardrails, safety layers, and hallucination mitigation
• Proficiency in Python; experience building production‑grade AI services.
• Experience with orchestrating pipelines using Airflow, KubeFlow, Vertex Pipelines, or similar tools.
• Understanding of microservices & APIs for integrating AI components.
• Experience working with structured and unstructured data (PDFs, images, text).
• Advanced English and ability to collaborate with cross‑functional teams, including engineering, product, and domain experts.

We offer*:

• Flexible working format - remote, office‑based or flexible
• A competitive salary and good compensation package
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
