  • Architect scalable AI services using ML frameworks, model-serving tools, APIs, Docker, Kubernetes, and CI/CD pipelines.
  • Develop and optimize retrieval systems using embeddings, vector databases, semantic search, reranking, and structured data sources.
  • Fine-tune, adapt, and evaluate LLMs for domain-specific use cases using prompt engineering, supervised fine-tuning, LoRA, or QLoRA.
  • Build automated evaluation frameworks to measure model quality, prompt performance, retrieval accuracy, reasoning reliability, latency, and cost.
  • Implement observability for AI systems, including tracing, logging, performance monitoring, drift detection, and output-quality review.
  • Translate prototypes and research concepts into reliable product features that can scale in production.
  • Partner with product managers, data engineers, backend engineers, analysts, and business stakeholders to define AI capabilities and technical tradeoffs.
  • Review architecture, provide technical guidance, mentor junior engineers, and promote strong engineering practices.
  • Create technical documentation, implementation plans, runbooks, and model lifecycle documentation.

Requirements

  • 5+ years of experience in machine learning engineering, AI engineering, data science engineering, or a related technical role.
  • 2+ years of experience building or shipping production GenAI, LLM, or AI-powered systems.
  • Advanced Python programming skills and experience building maintainable production software.
  • Hands-on experience with PyTorch, TensorFlow, Hugging Face Transformers, scikit-learn, or similar ML frameworks.
  • Experience with LLM applications, RAG systems, embeddings, vector databases, prompt engineering, and model evaluation.
  • Experience deploying AI / ML services using Docker, Kubernetes, CI/CD workflows, APIs, and cloud-native infrastructure.
  • Strong understanding of classical machine learning, deep learning, NLP, information retrieval, and model validation.
  • Ability to communicate complex AI concepts clearly to technical and non-technical stakeholders.
  • Experience mentoring engineers, reviewing technical designs, or leading complex AI engineering initiatives.
  • Advanced degree in Computer Science, Machine Learning, Artificial Intelligence, Data Science, or a related field (preferred).
  • Experience with agent frameworks such as LangGraph, AutoGen, CrewAI, or similar tools (preferred).
  • Experience with model-serving platforms such as vLLM, BentoML, Triton, Ray Serve, or similar systems (preferred).
  • Familiarity with ML observability, experiment tracking, model monitoring, and prompt/version management tools (preferred).
  • Experience with graph-based retrieval, knowledge graphs, multimodal models, large-scale data processing, or security-focused data products (preferred).
  • Experience with infrastructure-as-code, workflow orchestration, model routing, caching, batching, or quantization (preferred).
