About The Position

We build and scale mobile apps used by 15,000+ restaurants, shipping multiple times a day with strong tooling and observability. As a Senior Mobile Software Developer, you will take full ownership of React Native features from concept to production, delivering high-quality experiences across iOS and Android. You will build and iterate quickly by breaking work into small, shippable increments, using modern tooling (including AI) to move faster and smarter. Collaboration with your team to design scalable solutions, contribute thoughtful code reviews, and continuously improve how we build is key. Shipping with quality, including testing, performance, and reliability, will be built into your process. You will also raise the bar by mentoring others and helping evolve our engineering standards, tooling, and ways of working.
