Senior AI/ML Engineer (LLM & NLP)

About the role

A Senior AI/ML Engineer is sought to lead the development of core machine learning systems and AI-driven automation, focusing on LLM-based systems, NLP pipelines and intelligent workflows that turn complex, unstructured data into usable insights. The engineer works directly with senior leadership to shape technical direction and turn ambiguous product goals into concrete engineering solutions. The position is fully remote.

Key responsibilities

• Lead the design and development of machine learning systems and LLM-based applications
• Fine-tune and adapt large language models for domain-specific use cases
• Build NLP pipelines to extract structured data from complex, unstructured documents
• Translate product goals into technical and ML execution plans, and prioritize work with product signals, user feedback and backlog input
• Build evaluation systems, automated benchmarking pipelines and performance metrics tied to real-world outcomes
• Create feedback loops that use user corrections to continuously improve model performance
• Apply computer vision to extract data from PDFs and scanned documents, and build AI agents that interact with web systems using Playwright or Selenium
• Build scalable ML systems and supporting infrastructure from the ground up

Required profile

• 6+ years of Python development experience
• 4+ years in AI/ML engineering roles
• Strong experience building and deploying LLM-based systems (e.g., Claude, OpenAI models)
• Experience building NLP systems for information extraction or document understanding
• Experience integrating feedback loops or continuous learning
• Comfortable working in ambiguous environments and communicating clearly with technical and non-technical stakeholders

Required skills

• Python
• JavaScript/Node.js and React in production environments
• Model evaluation, benchmarking and performance measurement
• MongoDB and AWS
• Prompting, evaluation and iteration with modern LLM workflows
