Senior Mobile Developer, Growth (US)
About The Position
Nanit is moving families beyond overwhelm by transforming how parents understand their baby's early years. We combine advanced AI, real-world data from billions of sleep hours, and clinical expertise to deliver the clarity and confidence every parent deserves. Trusted by over one million families and backed by $125M in funding, we're building an entirely new category: predictive parenting intelligence. Here, your work directly impacts millions of families. Our team of scientists, engineers, and parents is small but mighty - we share a mission to make early childhood easier, healthier, and more connected. If you want to work on technology that genuinely matters, join us. You'll 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. You'll 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. We're looking for someone who holds context, makes decisions, unblocks themselves, and knows when a question is worth asking rather than waiting on a sync.
