AI / Machine Learning Engineer

About the Position

We are seeking an AI / Machine Learning Engineer to build and ship production AI systems for large-scale engagements across the USA, Israel, and Europe. This role is hands-on, production AI engineering - LLM architectures, autonomous agents, and fine-tuned models that ship and get measured by business outcomes, not benchmark scores.

Responsibilities

• Design and deploy scalable architectures built on Large Language Models
• Build and optimize AI agents that automate complex business processes
• Fine-tune models for domain-specific applications in Healthcare, FinTech, and Autonomous Systems
• Build reliable data pipelines and integrate AI components into production environments
• Define evaluation frameworks and quality metrics for AI features in production
• Advise on AI architecture tradeoffs - model selection, latency, cost, and reliability

Requirements

• Expert-level Python - you write clean, production-grade code, not just notebooks
• Hands-on experience with PyTorch, TensorFlow, or JAX
• Working knowledge of frontier LLM APIs - OpenAI GPT-4, Anthropic Claude, and Llama 3
• Proficiency with LangChain or LlamaIndex orchestration frameworks
• Deep understanding of RAG (Retrieval-Augmented Generation) architectures
• Experience with vector databases - Pinecone, Milvus, Weaviate, or Chroma
• Strong command of Pandas, NumPy, and Scikit-learn
• Solid grasp of Transformer architectures and the Hugging Face ecosystem
• Practical cloud and MLOps experience - AWS or Google Cloud, Docker, and Kubernetes
• Upper-Intermediate to Advanced English - all documentation and client reviews are in English

Nice to Have

• Experience fine-tuning models for domain-specific applications in regulated industries
• Background in autonomous navigation systems or mission logic
• Open-source AI contributions or a strong GitHub portfolio
• MLOps depth - model versioning, monitoring, and drift detection in production

We Offer

• Real production AI work on modern stacks - not legacy maintenance or POC theater
• Sophisticated projects for international tech leaders across the USA, Israel, and Europe
• A senior, distributed engineering team where every peer has shipped software at scale
• Priority consideration for upcoming senior and lead engineering roles as projects ramp
• Fully remote, flexible hours, B2B contractor model with transparent rates
• Direct access to technical decision-makers - no PM or agency layer in between
