Hiiya

Full-stack Engineer

• Own backend services that power core features across both apps—caller ID lookups, spam/fraud detection, call screening, real-time scam alerts, call transcription, and AI-generated summaries. This includes designing service architecture, writing production code, deploying to AWS, and operating systems at scale with high availability and low latency.
• Build and maintain mobile integrations that connect backend services to iOS and Android applications. You'll collaborate closely with mobile engineers to ensure seamless SDK behavior across platforms, debug platform-specific issues, and ship features that work reliably for millions of users.
• Scale infrastructure to support growing user bases and new feature development. You'll make decisions about how to handle increasing load, optimize costs, and maintain reliability as both products evolve.
• Make architectural and implementation decisions that balance speed, quality, and long-term maintainability. You'll encounter ambiguous problems—how to handle edge cases in call screening logic, how to structure services for rapid iteration on AI features, how to maintain a shared backend that serves two distinct products—and you'll drive toward solutions with ownership of the outcome.
• Collaborate across engineering, product, and design to ship features that matter. The Mobile Experience team operates with high autonomy, which means you'll be involved in shaping what we build, not just how we build it.
