The position also emphasizes Responsible and Explainable AI practices, along with production reliability through CI/CD, testing, monitoring, and risk-aware governance.

Responsibilities

• Design, build, and/or deliver ML models and components for real-world business problems in collaboration with Product and Data Science teams
• Build and scale large multi-tenant platforms to support model training and/or serving at scale
• Use ML modeling knowledge to inform infrastructure decisions, including model choice, data and feature selection, training, hyperparameter tuning, dimensionality, bias/variance, and validation
• Solve complex problems through application code, testing, model development, and deployment automation
• Collaborate as part of a cross-functional Agile team to create and enhance big data and ML software
• Retrain, maintain, and monitor models in production
• Leverage or build cloud-based architectures, technologies, and/or platforms to deliver optimized ML models at scale
• Construct optimized data pipelines to feed ML models
• Apply continuous integration and continuous deployment best practices, including test automation and monitoring, to support successful model and application deployments
• Manage code to reduce vulnerabilities, ensure risk-aware model governance, and follow Responsible and Explainable AI best practices
• Use programming languages such as Python, Scala, or Java

Requirements

• Bachelor’s degree or higher in Computer Science, Machine Learning, or a related quantitative field (including Statistics, Economics, Operations Research, Analytics, Mathematics, Engineering)
• At least 6 years programming with Python, Java, Golang, or C++
• At least 6 years ML experience with industry-standard frameworks PyTorch or Tensorflow and libraries such as Pandas, NumPy, and Scikit-learn
• At least 6 years experience using and operating large scale distributed systems such as Spark and Ray to prepare AI/ML data
• At least 4 years deploying and operating ML solutions in production and operating production services in the cloud (AWS, GCP, Azure), using Kubernetes to manage large scale containerized ML systems

Technologies

• Python, Scala, Java, Golang, C++, PyTorch, Tensorflow, Pandas, NumPy, Scikit-learn
• Spark, Ray, AWS, GCP, Azure, Kubernetes

Compensation

USD 229,900 - 262,400 per year for Machine Learning Engineer 5.

• Performance based incentive compensation, which may include cash bonus(es) and/or long term incentives (LTI)

Preferred Qualifications

• Master’s or doctoral degree in computer science, electrical engineering, mathematics, or a related field
• 5+ years of experience optimizing ML algorithms, configurations, and infrastructure
• 5+ years of experience following software development best practices including source control, testing, code reviews, and CI/CD
• 5+ years of experience building resilient software solutions with pre-production testing, advanced deployment techniques (one-box, blue/green, gradual dial-up), monitoring, alarms, and incident response plans
• 5+ years of experience with ML techniques and model types such as supervised, semi-supervised, unsupervised, and reinforcement learning, including regression, classification, and clustering
• 5+ years of experience with model architectures (RNNs, CNNs, LSTMs, Transformers) and training concepts including loss function, hyperparameters, regularization, plus evaluating accuracy and diagnosing common issues like underfitting and overfitting
• 5+ years of experience designing, implementing, and scaling production-ready data pipelines for training and evaluating ML models
• ML industry impact through conference presentations, papers, blog posts, open source contributions, or patents
• Ability to communicate complex technical and machine learning concepts clearly to a variety of audiences
