Data Scientist

OPPORTUNITY We are seeking a highly skilled Data Scientist / Machine Learning Engineer to help design, build, deploy, and maintain scalable machine learning systems within Antarctica Capital as part of the Octantis platform. A key initial area of focus for this role will be deep collaboration with the architect/author of an existing neural network used to predict risk factors associated with bonds. In this capacity you will develop an understanding of the existing modeling techniques; identify opportunities for improvement across model performance, infrastructure, reliability, and cost; and lead implementation of those improvements.

Beyond the initial focus area, this role will have significant opportunities to deliver impactful, value-generating capabilities within the firm and a fast, flexible, agile team on which to work.

KEY RESPONSIBILITIES:

Refactor Neural Network

• Collaborate with architect and author of neural network bond risk product to identify areas for improvement.

Ongoing

• Contribute to the design, development, and deployment of firm-wide architecture, norms, policies, infrastructure and methodologies for machine learning activities across multiple company groups.

• Design, develop, and deploy machine learning models into production environments.

• Collaborate with data scientists to translate prototypes into production-ready systems.

• Build and maintain data pipelines, feature stores, and model-serving infrastructure.

• Evaluate and optimize model performance, latency, and scalability.

• Implement automated training, testing, and deployment workflows (MLOps).

• Monitor models in production and address issues related to drift, performance degradation, or data quality.

• Conduct code reviews and ensure best practices in ML engineering and software development.

• Stay current with emerging ML/AI technologies and recommend tools or frameworks that improve team efficiency.

Other Duties as Assigned

EXPERIENCE

• 7+ years building machine learning models with Python and AWS.

• Hands-on experience with ML frameworks such as Pytorch and TensorFlow.

• Experience with ML observability and training platforms/technologies like ML Flow.

• Proficiency in building and deploying models using cloud platforms such as AWS (e.g. in Fargate)

• Solid understanding of algorithms, data structures, and software engineering principles.

Preferred:

• Experience with data and compute orchestration tools like AWS Step Functions or Apache Airflow.

• Exposure to large scale data warehousing and query engine technologies like Iceberg and Athena, and to columnar data storage formats like parquet.

• Experience working with and modernizing legacy software, including migrating from on-prem to cloud-based deployments.
