• At least 4 years of programming experience with Python, Java, Golang, or C++.
• At least 4 years of machine learning experience using industry-standard frameworks such as PyTorch or TensorFlow and libraries such as Pandas, NumPy, and Scikit-learn.
• At least 4 years of experience using and operating large-scale distributed systems such as Spark or Ray to prepare AI or machine learning data.
• At least 2 years of experience deploying and operating machine learning solutions in production, operating production services in the cloud (AWS, GCP, or Azure), and using Kubernetes to manage large-scale containerized machine learning software systems.

Nice To Haves

• Master's or doctoral degree in Computer Science, Electrical Engineering, Mathematics, or a related field.
• At least 3 years of experience optimizing machine learning algorithms, configurations, and infrastructure.
• At least 3 years of experience following software development best practices, including source control, testing, code reviews, and CI/CD.
• At least 3 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.
• At least 3 years of experience with machine learning techniques, model types, architectures, training concepts, and evaluating model accuracy and diagnosing common issues such as underfitting and overfitting.
• At least 3 years of experience designing, implementing, and scaling production-ready data pipelines for training and evaluating machine learning models.
• At least 1 year of experience as a technical lead developing machine learning solutions using industry best practices, patterns, and automation.
• Authored or co-authored a paper on a machine learning technique, model, or proof of concept.

Responsibilities

• Design, build, and deliver machine learning models and components that solve business problems in collaboration with Product and Data Science teams.
• Use understanding of machine learning techniques and issues to inform infrastructure decisions, including model, data, and feature selection; training; hyperparameter tuning; dimensionality; bias and variance; and validation.
• Write and test application code, develop and validate machine learning models, and automate testing and deployment.
• Collaborate with a cross-functional Agile team to create and enhance software for large-scale data and machine learning applications.
• Retrain, maintain, and monitor production models.
• Leverage or build cloud-based architectures, technologies, and platforms to deliver optimized machine learning models at scale.
• Construct optimized data pipelines to feed machine learning models.
• Apply continuous integration and continuous deployment practices, including test automation and monitoring, to deploy models and application code successfully.
• Manage code to reduce vulnerabilities, govern models from a risk perspective, and apply Responsible and Explainable AI best practices.
• Use programming languages such as Python, Scala, or Java.

Benefits

• Eligible for performance-based incentive compensation, which may include cash bonuses and/or long-term incentives.
• Comprehensive health, financial, and other benefits supporting total well-being.
