Specific duties are listed below, but may not be all-inclusive.

  • Managing complex identity and authorization models for internal and user-facing applications, including SSO, RBAC, ABAC, and ReBac (Zanizbar-style) authorization

  • Microsoft-based authentication and authorization
  • AWS Cloud Architecture
  • Cloud networking (Route 53, Cloudflare, AWS VPCs)
  • Secure development at all levels, and defense in depth
  • Transactions, orders, subscriptions, entitlements, and resource provisioning
  • Real-time and event-driven architecture / asynchronous messaging
  • Building and managing ETL/ELT pipelines and batch data processing
  • Developing in compliance with SOC 2 Type II and privacy requirements (GDPR/CCPA)

Skills and Abilities

  • Ability to identify when niche specialists are needed and effectively delegate work to contractors, ensuring output meets quality standards and includes sufficient knowledge transfer for ongoing in-house maintenance
  • Very hands-on while also able to look at things holistically to ensure back-end technology works together in as cost-effective a way as reasonably possible
  • Comfortable serving as the primary AWS root user and administrator, or overseeing that role as applicable
  • Platform and product mindset
  • Very comfortable with infrastructure as code
  • Commitment to demonstrate consistently the Augustine Institute’s core values including:
