Job Overview

We are looking for an experienced Senior AI/ML Engineer to join our Generative AI team. You will work on the design and implementation of cutting-edge AI systems-including Retrieval-Augmented Generation (RAG) pipelines, multimodal generative models (GPT, DALL·E, etc.), and their integration into high-load product environments and internal workflows. This role combines hands-on engineering with architectural thinking to scale Gen AI across the company. 

What will you do?

  • Design and implement RAG systems with hybrid retrieval (dense/sparse), embeddings, and orchestrated prompt pipelines.
  • Architect and deploy LLM-based solutions using open-source and proprietary models (LLaMA, Mistral, GPT-4, Claude).
  • Build scalable ML pipelines for batch and real-time inference, retraining, evaluation, and observability.
  • Integrate Gen AI models (text, image, multimodal) into core business processes and customer-facing products.
  • Collaborate with cross-functional teams-product, engineering, data science, and ops-to deliver AI-powered features.
  • Evaluate Gen AI models for performance, cost, scalability, and alignment with company use cases.
  • Ensure robust architecture and security practices in deploying AI solutions within existing IT ecosystems.
  • Contribute to tooling and platform selection for model deployment, inference orchestration, and data flow automation.
  • Document and evolve best practices in Gen AI architecture across the organization. 

What are we looking for?

  • 5+ years of experience in Machine Learning, including deployment of production-grade AI solutions.
  • Expertise in NLP, Transformers, and modern deep learning architectures (RAG, BERT, T5, diffusion models, etc.).
  • Strong proficiency in Python and ML frameworks (PyTorch, TensorFlow, HuggingFace, LangChain, etc.).
  • Hands-on experience with vector databases (FAISS, Qdrant, Weaviate) and semantic search architectures.
  • Proficient with DevOps/MLOps practices and tools: Docker, Kubernetes, CI/CD, monitoring, logging.
  • Experience with cloud platforms (AWS, GCP, Azure) and their AI/ML service stacks.
  • Strong architectural thinking with a focus on scalability, performance, and cross-system integration.
  • English language proficiency at B2 or higher.

What additional skills will help you stand out?

  • Experience deploying multimodal models (e.g. DALL·E, Stable Diffusion, Whisper).
  • Familiarity with Gen AI use cases in games, content creation, and enterprise automation.
  • Knowledge of ethical AI practices and governance.
  • Background in leading small teams or coordinating AI projects end-to-end.
