  • Manage release processes for both iOS and Android, handling store submissions and certificates with precision
  • Write comprehensive tests, conduct code reviews, and document architectural and decision rationale
  • Maintain and improve the health of the codebase through refactoring, managing technical debt, and proposing structural improvements
  • Collaborate closely with the client via Slack/Teams/email, providing clear, detailed updates and active communication
  • Participate in weekly status reports and monthly governance calls, representing the technical voice of the platform

  • Working familiarity with GCP: Cloud Run, Cloud Functions, Cloud Storage, Cloud Logging, IAM, and service account management

  • Customer-facing professionalism — capable of conducting calls, explaining trade-offs, and providing professional status updates

It is a strong plus if you have:

  • Experience in transportation, logistics, ride-hailing, or booking platforms
  • Familiarity with Google Maps Platform, geolocation, route optimization, or driver tracking
  • Payment integration experience with Stripe, HyperPay, PayTabs, or similar local Saudi gateways
