• Driving backend innovation by writing clean, maintainable code and refining our service architecture to support rapid product growth.
• Leading development initiatives including threat modeling, performance tuning, and reliability engineering to harden our systems against evolving security challenges.
• Mentoring engineers and collaborating across teams to shape our technical roadmap and foster a culture of secure-by-default engineering.

Required Qualifications

• Significant experience building and operating distributed backend systems in a modern, typed language.
• Strong proficiency in Rust or Kotlin. We value deep expertise in either language and a pragmatic approach to choosing the right tool for the job.
• Deep expertise in modern authentication and authorization concepts (e.g., OIDC, OAuth2, RBAC/ABAC) and their practical application in building secure services.
• Hands-on experience with cloud-native technologies, particularly Kubernetes and cloud platforms like GCP, AWS or Azure.
