  • Strong foundation in core machine learning frameworks and methodologies, including experience with deep neural networks and transformer-based architectures.
  • Working knowledge of statistical theory, including probability distributions, Bayesian reasoning, and estimation techniques.
  • Ability to collaborate effectively and articulate complex technical concepts in accessible ways.
  • A track record of creative problem solving and self-directed learning.

Preferred Background

  • Exposure to cloud environments, particularly AWS.
  • Understanding of software development lifecycles, version control, CI/CD pipelines, and Infrastructure as Code tools like Terraform.
  • Basic familiarity with containerized systems and orchestration platforms such as Kubernetes.
  • Interest or prior experience in financial technology domains.
