Full Job Description
Youll be the founding mobile engineer on a new Growth team - a cross-functional squad owning the full customer funnel, from first consideration through purchase, subscription, engagement, and referral. Youll also be the first R&D engineer based at our US site, hybrid, with your manager and the rest of the team in a different time zone.

Were looking for someone who holds context, makes decisions, unblocks themselves, and knows when a question is worth asking rather than waiting on a sync.

What Youll Be Doing -
  • Build and ship features end-to-end across iOS and Android - paywalls, onboarding, subscription flows, in-app messaging, referral mechanics - working at every layer of the client stack with backend, product, design, and QA
  • Build the client side of how we measure: feature flags, experiment assignment, event instrumentation - every bet the team makes gets evaluated on data
  • Review code, evaluate implementations, and give feedback that raises the bar
  • Work with Kotlin Multiplatform and Compose for iOS - were already building with it, and wed love to talk if you have experience with KMP or want to grow into it
Who you are -
  • 5+ years building production mobile apps, on both iOS and Android
  • Strong Kotlin and Swift
  • Production experience with Jetpack Compose and/or SwiftUI
  • Experience owning a project end to end and shipping it
  • Solid grounding in OOP, concurrency and clean architecture
  • Real care about UX, testing and code quality
  • Kotlin Multiplatform - an advantage

Why Youll Love Working Here -
  • Hybrid in-office schedule
  • Remote work from home month in August
  • Flexible PTO (we trust you to take the time you need)
  • Equity options so you can share in our growth
  • Paid parental leave for all new parents
  • Employee discounts on Nanit products
  • Work from home stipend
  • Monthly team events

EEO, Salary and Location:

This is a hybrid role that will require prospective candidates to be in our NYC office 3 days per week.

Salary Range: $170 to $190 base salary + equity and benefits. The base pay is one component of Nanits total compensation package, which may also include access to healthcare benefits, a 401(k) plan, short-term and long-term disability coverage, and basic life insurance. Ultimately, in determining your pay, well consider your location, experience, and other job-related factors.
