What you’ll do

• Design, build, and deliver ML models and components in collaboration with Product and Data Science
• Build and scale massive multi-tenant platforms for large footprint model training and/or serving
• Apply ML modeling knowledge to inform ML infrastructure decisions across model choice, data and feature selection, training, hyperparameter tuning, dimensionality, bias/variance, and validation
• Develop and test application code, build and validate ML models, and automate tests and deployment
• Work in a cross-functional Agile team to create and enhance big data and ML application software
• Retrain, maintain, and monitor models deployed in production
• Leverage or build cloud-based architectures, technologies, and platforms to deliver optimized ML models at scale
• Construct optimized data pipelines that feed ML models
• Use CI/CD best practices, including test automation and monitoring, to support successful deployments
• Ensure code is well-managed to reduce vulnerabilities, that models are well-governed from a risk perspective, and that ML follows Responsible and Explainable AI best practices
• Use programming languages such as Python, Scala, or Java

Required qualifications

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

Technologies

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

Benefits

• Comprehensive, competitive, and inclusive set of health, financial, and other benefits supporting total well-being
• 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, CI/CD, etc.
• 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 preparing incident response plans
• 5+ years of experience working with ML techniques including supervised, semi-supervised, unsupervised, and reinforcement learning, and model types such as regression, classification, and clustering
• 5+ years of experience with model architectures including RNNs, CNNs, LSTMs, and Transformers, plus training concepts and evaluating model accuracy and diagnosing 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
