Job description

  • Lead macOS app development, architecture, performance, deployment, and long-term scalability.
  • Own the quality bar: profiling, debugging, optimizing for speed and stability.
  • Ensure compatibility across managed environments, including MDM and restricted setups.
  • Collaborate closely with backend and data teams to integrate APIs and improve system reliability.
  • Guide and mentor team members and other developers, helping elevate the overall engineering craft.
  • Build for the edge cases, from sandboxing and permissions to enterprise deployments.
  • Contribute to our CI/CD and testing practices, ensuring smooth builds and updates.

Requirements

  • Expert in Swift and macOS app development, with a deep grasp of Apple frameworks, security, and system design.
  • Proven experience in profiling, debugging, and performance optimization across varied Mac environments.
  • Comfortable working in managed device contexts (MDM), understanding sandboxing, permissions, and deployment constraints.
  • Familiar with API integrations, backend collaboration, and maintaining reliable interfaces.
  • A stickler for detail, you notice inconsistencies others miss and care deeply about polish.
  • Experience with SwiftUI and Catalyst for cross-platform work is a strong plus.

Bonus points

  • Knowledge of Django REST Framework or similar backend stacks.
  • Understanding of CI/CD pipelines and automated macOS testing.
  • Experience in security-focused or enterprise-managed environments.
  • Familiarity with enterprise compliance and privacy standards.
