MLOps Engineer

We are looking for an MLOps Engineer who knows that a model is only as good as the pipeline behind it — someone who has actually kept ML systems running in production, not just deployed a tutorial to a notebook. You will work on international projects for clients in banking, insurance, and telco (US, Netherlands, UK), building the infrastructure that makes AI reliable at scale. About Halcyon Labs At Halcyon Labs, we focus on continuous self-development and acquiring new knowledge. If you are a fast learner, want to participate in international projects, are a team player, and can work independently - join us! We provide our clients with more than just code - we want to equip them with tools that allow their businesses to flourish. Our clients’ success is our success, which is why we ensure that everyone who creates Halcyon Labs has a long-term goal in mind. At Halcyon Labs, you’ll have the opportunity to discuss your challenges and solutions with our team of experts, including experienced architects who are always ready to share their knowledge and guide you through complex technical decisions.
