# Senior Machine Learning Engineer (NLP)

We're helping an early-stage startup build an AI-powered platform, and we're looking for a Senior Machine Learning Engineer (NLP) to help shape the core AI/ML architecture behind it. This is a hands-on, high-impact role: you'll design, build, and deploy ML systems end-to-end, working directly with the founding team to deliver 10x value to our clients. If you love solving open-ended problems with AI and want to shape both the product and the engineering culture from day one, this is for you. Porto (hybrid - 2x/week in office) + Up to €90k/year What You'll Be Working On You'll own ML/AI systems at the heart of the platform - from model development and training through to deployment and monitoring. Day to day, that means building intelligent systems for document processing, web data parsing, classification, search, and entity matching, applying modern LLM techniques to messy, real-world problems. You'll run experiments with new models, data strategies, and agentic AI approaches, while balancing innovation against production realities like reliability, performance, and safety. Beyond the code, you'll help set the standards - defining best practices and tooling for AI development across
