Buzz Me Up is building the next generation of AI-powered building access technology. Our mobile-first platform transforms outdated intercom systems into smart, software-only solutions that empower tenants, landlords, and property managers with secure and convenient access control — no hardware required.

We are seeking a talented Mobile Engineer with strong React Native (Expo) experience to join our lean, fast-moving team. This role will own the mobile experience, from onboarding flows to real-time call handling, helping shape a product that residents love to use daily.

What You’ll Do

  • Build and refine core user-facing features, including intercom call handling, notifications, and call history.
  • Collaborate with backend engineers to integrate APIs (Twilio, Firebase, Clerk, Stripe).
  • Optimize app performance, responsiveness, and reliability.
  • Work closely with design and product to improve UX and deliver seamless onboarding.
  • Participate in code reviews, contribute to best practices, and help improve our technical processes.
  • Troubleshoot bugs and deliver quick fixes to maintain a high-quality user experience.
  • Deploy updates to the App Store and manage release cycles.

What We’re Looking For

  • 3+ years of mobile engineering experience with a strong track record of shipping apps.
  • Expertise with React Native and Expo.
  • Strong understanding of mobile UX and design principles.
  • Familiarity with integrating APIs and third-party SDKs (e.g., Firebase, Twilio, Stripe).
  • Experience with state management, navigation libraries, and offline data handling.
  • Solid understanding of debugging, testing, and performance optimization.
  • Comfortable working in a fast-paced startup environment where priorities evolve quickly.
  • Excellent communication skills and a collaborative mindset.

Nice to Have

  • Exposure to VoIP or real-time communications (CallKit, push notifications).

Why Join Us?

  • Work on a real-world problem that impacts urban living and smart cities.
  • Competitive salary of $120,000 CAD per year plus equity in a fast-growing startup.
  • Flexible remote-first environment (with Vancouver roots).
  • Opportunity to shape the direction of a product used by thousands of residents.
  • Be part of a small, mission-driven team where your contributions have an immediate impact.
