Company

hirify.global provides an intelligent orchestration platform for DevSecOps, helping organizations improve developer productivity, operational efficiency, security, compliance, and software delivery.

What you will do

• Design and ship authorization changes in the Ruby on Rails monolith, including systems handling hundreds of permission checks per request.
• Own authorization workstreams from problem definition through feature-flagged rollout, dual-run verification, and cleanup.
• Build and extend fine-grained permissions for tokens and roles while maintaining a coherent permission catalog.
• Strengthen authorization enforcement across GraphQL and REST APIs and improve system reliability, performance, and security.
• Refactor policy code so the Rails monolith and the Rust authorization engine can evaluate shared permission definitions without changing existing behavior.
• Collaborate with authentication, platform, AI, and modular-service teams while documenting technical decisions in a fully asynchronous organization.

Requirements

• Significant experience building and operating production Ruby on Rails applications.
• Experience designing or implementing authorization systems, including role-based access control and fine-grained permissions.
• Security mindset with the ability to assess permission bugs and their potential blast radius.
• Experience making incremental changes to large, long-lived codebases, including feature-flagged rollouts and safe migrations.
• Working knowledge of GraphQL, API authorization patterns, and performance considerations at scale.
• Strong written communication for asynchronous collaboration through design documents, architecture decision records, and code reviews.

Nice to have

• Rust, gRPC, Protocol Buffers, Cedar, Zanzibar-style authorization systems, Go, or service-oriented architecture experience.
• Transferable experience in identity, policy engines, or platform security.

Culture & Benefits

• Fully remote work with a distributed team working across time zones.
• Fully asynchronous collaboration with decisions made in writing.
• Health, financial, and well-being benefits for full-time employees.
• Flexible paid time off, parental leave, and equity compensation.
