Senior iOS Engineer at In Tandem

At In Tandem, our tech solutions—which include OurFamilyWizard, Cozi, FamilyWall, and Custody Navigator—work in tandem with families to simplify daily life, fostering connection, organization, and peace of mind throughout key stages and milestones of family life.

We believe technology can champion deeper connections within families, strengthen bonds, and improve communication. Our family of brands provides a range of solutions that streamline daily routines, offer resources and guidance during challenging times, and help families navigate those challenges with confidence, calm, and ease.

We’re seeking a Senior iOS Engineer to join our Growth team. This team is focused on the most critical moments of the customer journey: helping families sign up, subscribe, activate, and manage their accounts in ways that maximize both user experience and business impact. 

Getting to know teammates, technology, and tactics. 
In your first month, you’ll set up your local environment, ship your first small contribution, and learn the rhythms of our pod. You’ll get exposure to our signup, payment, and onboarding flows, while building connections with product, design, QA, and backend teammates. 

Try, learn, ship. 
By day 60, you’ll be comfortable operating within our development lifecycle from planning through production releases. You’ll have hands-on experience running experiments in the iOS app, contributing to in-app purchase flows, and collaborating on cross-platform initiatives. You’ll begin designing instrumentation to ensure experiments produce clean, actionable data. 

Solidifying the foundation. 
By 90 days, you’ll be an autonomous operator, able to own the delivery of subscription and onboarding flows end-to-end. You’ll shape pod-level technical plans, contribute reusable Growth components, and mentor peers on best practices. You’ll help balance speed of iteration with app quality and user trust. By this point, you’ll be an active participant in our Mobile Guild, bringing your experience and expertise to bear on issues and opportunities that arise for your peers. 

Accelerate growth. 
Beyond your first few months, you’ll influence platform-level decisions in Growth (e.g., signup journeys across iOS, Android, and Web). You’ll integrate AI-powered tools into workflows, scaling your own impact and helping the team adopt new ways of working. You’ll continue to drive experiments that improve conversion, activation, and retention, directly impacting top-line results. 

Great mission. Creating a safe and productive environment for families to co-exist is extremely important for us; we’ve been doing it for 20+ years and are deeply motivated by adding value to the lives of parents, children, and practitioners.

Growing team. While we’ve been around for a while, we continue to evolve and innovate. That’s what keeps us going! You’ll have an opportunity to contribute meaningfully to our organization as we hit our second stride.

Amazing Culture. In Tandem has a positive and supportive culture—we look for people who are curious, inventive, and work to be a little better every single day. In our work together, we aim to be smart, humble, hardworking and, above all, collaborative.
