  • Collaborate with Security, Authentication, Database, and Platform teams on authorization stack initiatives, aligning designs and implementation plans.
  • Solve complex performance challenges in authorization, including query optimization, caching strategies, and database decomposition, with a focus on PostgreSQL.
  • Design and evolve authorization systems that work across multiple deployment models and multi-tenant architectures while maintaining security and reliability.
  • Drive improvements to authorization security, maintainability, and developer experience through code review, documentation, and technical leadership.
  • Contribute to architectural decisions for authorization features with a long-term strategic view, balancing immediate needs with future scalability.
  • Mentor and support other engineers in authorization patterns, policy-based access control, and secure coding practices in a fully remote, asynchronous environment.

What you’ll bring

  • Professional experience building and maintaining production applications with Ruby on Rails and Vue.js or similar modern frontend frameworks.
  • Strong understanding of authorization models, including role-based access control, attribute-based access control, and fine-grained permission patterns.
  • Experience designing and optimizing high-scale backend systems, including PostgreSQL performance tuning, query optimization, and effective caching strategies.
  • Familiarity with or interest in policy-based authorization systems and modern policy languages such as Cedar or Rego.
  • Understanding of core security principles, including threat modeling, least-privilege access, and zero-trust architectures.
  • Experience working with distributed systems and service-to-service communication in a cloud or multi-tenant environment.
  • Demonstrated ability to own complex technical initiatives from design through production deployment in an asynchronous, remote setting.
  • Strong collaboration and communication skills, with openness to learning and applying transferable skills from adjacent domains or technologies.

Your decision to complete the form and your answer will not harm you in any way.
