Senior Backend Engineer at Intandem — Remote

At In Tandem , we build technology that helps families manage everyday routines and navigate life’s biggest transitions. Through our four brands—OurFamilyWizard, Cozi, FamilyWall, and Custody Navigator—we help families stay organized, communicate well, and foster healthy childhoods. We believe technology should strengthen relationships and make daily coordination less complicated. Everything we create is designed to lighten the mental load, reduce conflict, and support families through big and small moments. If you want your work to make a real difference in the daily lives of parents and kids, In Tandem is the place where your impact will truly matter. This is a senior engineering role for someone who has already made the shift to AI-native development. Your day is built around writing specifications, orchestrating agents, and reviewing the features they deliver. Your output is measured in features shipped and outcomes validated. You're grounded in backend engineering — Java/Spring is our stack and preferred — but we're open to candidates whose depth is in another statically typed language (Kotlin, C#, Go) or who bring full-stack range (React/Web, iOS, Android) on top of real backend chops. What we won't compromise on is the AI-native operating model and the systems judgment that lets you review agent output critically. This permanent role is structured as a rotation, giving you broad platform exposure and accelerated career growth across multiple teams and products before you find your long-term home in the engineering organization. You'll collaborate with product managers, designers, QA analysts, automation engineers, and web and mobile engineers to solve meaningful problems for parents, children, and practitioners across our platforms — using AI as a force multiplier at every layer of the SDLC. Please note: we're only accepting applicants located in the United States and are unable to provide sponsorship at this time.
