Machine Learning Engineer II
Xometry is seeking a Machine Learning Engineer II to join our team in Buenos Aires, Argentina. In this role, you will design, deploy, and maintain robust statistical and machine learning models, working closely with data scientists to translate research and experimentation into reliable, high-impact systems. You will apply strong data intuition and engineering judgment to improve model performance, reliability, and observability, while building predictive models that support pricing, cost estimation, and sourcing recommendations.
Key responsibilities include designing, building, and optimizing machine learning models to enhance Xometry’s platform and business operations. You will analyze large datasets to extract meaningful patterns and insights, collaborate with cross-functional teams to integrate machine learning models into production systems, and learn and apply best practices in model evaluation, performance tuning, and deployment. Additionally, you will influence technical direction by identifying opportunities to improve modeling approaches, data quality, and system architecture.
The ideal candidate will have a bachelor’s degree, with an advanced degree (M.S. or PhD) in computer science, machine learning, AI, or a related field highly preferred. You should have experience deploying and maintaining machine learning models in production environments, with 4+ years of experience in machine learning, focusing on data engineering and/or data science. Proficiency in Python, including key libraries such as PyTorch, TensorFlow, pandas, and numpy, is required, along with a strong background in probability, statistics, and optimization techniques relevant to generative modeling. Familiarity with cloud computing resources and tools for model training and deployment (e.g., AWS SageMaker) and software engineering principles, including version control, reproducibility, and continuous integration, is also desired. Experience in the manufacturing, supply chain, or similar industries is a plus.
Xometry offers a competitive benefits package, including 401(k) match, medical, dental, and vision insurance; life and disability insurance; generous paid time off including vacation, sick leave, floating and fixed holidays, maternity and bonding leave; EAP, other wellbeing resources; and much more.
