Overview Come build community, explore your passions, and do your best work at Microsoft while helping a team deliver machine learning (ML) capabilities that are reliable, measurable, and ready to integrate into real products and services. This opportunity will allow you to bring your aspirations, talent, potential and excitement for the journey ahead. As a Machine Learning Engineer (MLE), you will contribute—under guidance and with support from teammates—to understand ML requirements for a feature, prepare data, train baseline models, and evaluate results using standard metrics. This opportunity will allow you to grow your skills in ML workflows, model integration, and engineering practices that support security, privacy, accessibility, and responsible AI. Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees, we come together with a growth mindset, innovate to empower others and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond. Responsibilities - Implements data preprocessing steps, baseline models, and evaluation approaches under supervision. - Contributes small, well-defined components of ML workflows (e.g., dataset preparation, training utilities, evaluation scripts) with guidance. - Supports integration of ML models into existing systems and services, coordinating with engineering partners as needed. - Follows established practices for reproducibility, logging, monitoring, and secure development throughout the ML lifecycle. - Collaborates with teammates and partner teams to validate end-to-end functionality prior to release. - Learns and applies team processes related to security, privacy, accessibility, and responsible AI in day-to-day work. Qualifications Required Qualifications - Master's Degree in Computer Science, or related technical discipline with proven experience coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience. - Proficiency to speak, write and read in English language. Preferred Qualifications - Proficiency in one programming language (Python preferred) and common ML libraries (e.g., scikit-learn, PyTorch, TensorFlow). - Understanding of ML and GenAI fundamentals (e.g., supervised learning, evaluation metrics, overfitting/underfitting, regularization, embeddings, tokenization, transformers). - Ability to manipulate structured and unstructured data (e.g., pandas, SQL). - Familiarity with Git, code reviews, testing, and debugging in a collaborative environment. - Interest in learning deployment patterns, monitoring/observability, and responsible AI practices. This position will be open for a minimum of 5 days, with applications accepted on an ongoing basis until the position is filled. Microsoft is an equal opportunity employer.
