  • Design and implement web portals and API services for data management using a combination of modern web technologies.
  • Develop, implement, and maintain Kubernetes deployment recipes for data portals, catalogs, API gateways, and other ancillary services like key-value stores and databases.
  • Implement solutions for MLOps including model lifecycle management and storage, as well as integration with existing platforms like MLFlow.

Collaboration

  • Partner closely with internal platforms, cybersecurity, and account management teams to ensure the platform meets security, compliance, role-based access controls, and usability expectations.
  • Participate in cross-functional projects related to platform enhancements and cluster lifecycle automation.
  • Be able to represent the DAPS team with internal collaborators and partners across the lab.

Basic Qualifications:

  • BS degree and 3+ years of relevant experience or equivalent experience.
  • At least two years of experience with data management platform and tools development.
  • At least two years of experience with full stack application and API development.
  • Experience with CI/CD tooling, GitOps, and Kubernetes.
