  • Own engineering standards across the current platform and target architecture, including coexistence during migration.
  • Lead, coach, and develop engineering teams, including DevOps and platform functions, and support Tech Leads.
  • Foster a culture of ownership, accountability, continuous improvement, and blameless incident review.
