About the Role
We’re looking for a Senior Mobile Engineer with full stack capabilities to help build a consumer-facing mobile product from the ground up.

  • 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
  • Exposure to security-related domains (authentication, fraud detection, phishing, etc.)
  • Experience working in fast-paced innovation or experimentation teams
