About the role

At Mochi, our engineering team operates with exceptional leverage.
We believe in high talent density, where a focused, elite team powers a profitable, nine-figure ARR healthcare platform serving hundreds of thousands of patients.
Because of our high scale-to-team ratio, we do not operate in isolated technical silos.

You will leverage the full power of Expo to deliver a flawless, cross-platform experience, utilizing EAS (Expo Application Services) to manage our build pipelines, configure custom native modules via Config Plugins, and push seamless over-the-air (OTA) updates to iterate rapidly and ensure patients always have the latest clinical tools.
Build Agentic Workflows: Mochi is an AI-first engineering org.
You will not only utilize frontier agentic models to accelerate your own development, but you will also integrate AI capabilities directly into our mobile interfaces to automate clinical operations and streamline patient support.
Raise the Engineering Bar: Own key mobile architectural decisions, establish patterns for strict code reuse between our web and mobile clients, and elevate the engineers around you through rigorous code review and mobile testing practices.
It's designed for deep work and casual collaboration
We believe that face-to-face interaction builds a culture of excellence and allows us to deliver the best outcomes for the patients and providers we serve.

You have operated high-stakes mobile systems.
You have 5-7+ years of frontend engineering experience, with deep, specialized focus on React Native and Expo.
You are an Expo and Mobile Infrastructure expert.
You are a full lifecycle owner.
You can describe specific ways these models have structurally changed how you code, while retaining the deep technical skepticism required to audit, verify, and own its output.
You are a collaborative builder.
You have low ego, high standards, and excellent communication skills.
You are excited to work in-person.
If you are targeting Staff leveling: We expect a demonstrated track record of setting technical direction across teams, navigating deep ambiguity, and measurably leveling up the engineers around you.

Our mobile stack is React Native, Expo, TypeScript, and modern state management tools.
Experience with native iOS (Swift/Objective-C) or Android (Kotlin/Java) is a strong plus for when we need to drop down into native code, but we index on React Native mastery and product sense.

🌴 Time to Recharge - Enjoy unlimited PTO, generous company holidays, and true flexibility.
The base salary for this full-time position ranges from $230,000 to $280,000, in addition to equity and benefits.
