About the role

  • Sanas is revolutionizing the way we communicate with the world’s first real-time algorithm, designed to modulate accents, eliminate background noises, and magnify speech clarity.
  • Pioneered by seasoned startup founders with a proven track record of creating and steering multiple unicorn companies, our groundbreaking GDP-shifting technology sets a gold standard.
  • Sanas is a 200-strong team, established in 2020. In this short span, we’ve successfully secured over $100 million in funding. Our innovation have been supported by the industry’s leading investors, including Insight Partners, Google Ventures, Quadrille Capital, General Catalyst, Quiet Capital, and other influential investors. Our reputation is further solidified by collaborations with numerous Fortune 100 companies. With Sanas, you’re not just adopting a product; you’re investing in the future of communication.
  • Job Overview: We’re looking for a hands-on Senior Mobile App Engineer to lead development of our React Native application that delivers near real-time, voice-to-voice translation. You’ll own core client features—from FaceTime-like calling and live captioning to buttery-smooth UI animations—and collaborate closely with our speech/ML, product, and backend teams to ship a high-quality, low-latency experience. Experience with React Native is required; with knowledge writing and Kotlin plugins a strong plus. AV experience is a plus.

Requirements

  • 5+ years building and shipping consumer-grade mobile apps
  • 3+ years with React Native and TypeScript
  • Demonstrated ownership of a major app or feature used by real customers (App Store/Play Store)
  • Strong UI/UX instincts with React Native animations (e.g., Reanimated, Gesture Handler; familiarity with Lottie or Skia is a plus)
  • Experience integrating real-time or streaming features (sockets, media, or similar)
  • Comfortable bridging to native: Swift/Objective-C (Kotlin/Java a plus)
  • Fluency with mobile CI/CD, OTA updates (e.g., CodePush/EAS), crash reporting, and performance tooling
  • Excellent product judgment, collaboration, and communication; thrive in fast- paced, in-person startup environment
