environments




* Experience with backend services and APIs
* Familiarity with AI-assisted development tools (Claude, ChatGPT, Gemini,
etc.)
* 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
* Experience working on early-stage initiatives
* Experience with consumer-facing products

phishing, etc.)
* Experience working in fast-paced innovation or experimentation teams
