Senior Machine Learning Engineer (Remote-Eligible)

As a Capital One Machine Learning Engineer (MLE), you'll be part of an Agile team dedicated to productionizing machine learning applications and systems at scale. You’ll participate in the detailed technical design, development, and implementation of machine learning applications using existing and emerging technology platforms. You’ll focus on machine learning architectural design, develop and review model and application code, and ensure high availability and performance of our machine learning applications. You'll have the opportunity to continuously learn and apply the latest innovations and best practices in machine learning engineering.

Team Info:

The Flamingos are a cross functional team that works on the Feature Registry and more generally, Governance, within the Feature Platform. What is a feature? Features are “well-defined calculations and associated metadata for reuse in machine learning models, analyses, or other operational applications”. The Feature Platform is “the enterprise-wide platform that enables the discovery, computation, use, and monitoring of features for real-time and batch machine learning models and analytics”. The Flamingos work on everything from API backends to CLIs to UI front ends to support the registration, discovery, lifecycle, access, governance, and metadata management of Features on the Feature Platform. There is also work planned for small data pipelines and state machines to facilitate automation of the above. The core stack is currently centered around Serverless AWS Lambda API’s, with optionality for language choice (Python/NodeJS/Java), and a React front end. This role involves facilitating the advancement of our Feature Platform ecosystem through Machine Learning Engineering Best Practices. The Flamingos also put a high value on innovation and learning, especially about our ML Ecosystem.

What you’ll do in the role:

  • The MLE role overlaps with many disciplines, such as Ops, Modeling, and Data Engineering. In this role, you'll be expected to perform many ML engineering activities, including one or more of the following:

  • Design, build, and/or deliver ML models and components that solve real-world business problems, while working in collaboration with the Product and Data Science teams.

  • Inform your ML infrastructure decisions using your understanding of ML modeling techniques and issues, including choice of model, data, and feature selection, model training, hyperparameter tuning, dimensionality, bias/variance, and validation).

  • Solve complex problems by writing and testing application code, developing and validating ML models, and automating tests and deployment.

  • Collaborate as part of a cross-functional Agile team to create and enhance software that enables state-of-the-art big data and ML applications.

  • 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.

  • Leverage continuous integration and continuous deployment best practices, including test automation and monitoring, to ensure successful deployment of ML models and application code.

  • Ensure all code is well-managed to reduce vulnerabilities, models are well-governed from a risk perspective, and the ML follows best practices in Responsible and Explainable AI.

  • Use programming languages like Python, Scala, or Java.
