- Solid understanding of mobile platform internals (permissions, messaging systems, sandboxing, etc.)
- Experience designing scalable architectures and making system-level decisions
- Comfortable working with cloud infrastructure and distributed systems
- Ability to operate with high autonomy and navigate ambiguous requirements
- Strong communication skills and experience working with senior stakeholders

Nice to Have
