Senior Backend Engineer, Java

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.

As a Senior Backend Engineer (Java), you'll join us in a unique rotational capacity that offers broad platform exposure and accelerated career growth. This permanent role is structured to give meaningful experience across multiple teams and products before finding your long-term home within our engineering organization.

In this role, you'll directly contribute to features that make everyday life a little bit easier for families. Working as part of product teams, you'll collaborate with product managers, designers, QA analysts, automation engineers, and other web and mobile engineers to solve meaningful problems for parents, children, and practitioners across our platforms.

We're looking for someone experienced in creating high quality software with deep knowledge of relational databases, Hibernate, and the Spring Framework. Additionally, we value individuals familiar with microservices architecture and AI integrations who are passionate about solving problems. In this role, you'll be building robust, scalable backend services and APIs that power our family coordination platforms, working with modern technologies including AI-powered features that directly impact millions of families.

Please note, we're only accepting applicants located in the United States and are unable to provide sponsorship at this time.

What you will accomplish:

Getting to know teammates, technology, and tactics.

Your first day will be spent partnering with your manager and a colleague to get your local environment set up and fixing a bug. The following 29 days involve connecting with engineers across Messages, Calls, and Reporting to gain a high-level understanding of how we prioritize, plan, build, and deliver value to families on OurFamilyWizard. Through this rotational role, you'll build deeper connections across product and platform as you get immersed in daily and weekly agile rituals and the API guild. Your manager will set up recurring 1:1's and begin the ongoing discussion of personal and shared goals alongside rotation objectives. Technical work will focus on gaining exposure to services within Gandalf's domain and understanding how they integrate with the broader platform architecture. By the end of your first month, you'll be acclimated to the operating rhythm and gaining confidence by taking on increasingly complex tasks.

Try, learn, ship.

By day 60, you will be comfortable operating within our SDLC from planning through production releases. You'll have a broad understanding of our backend architecture, and a deeper understanding of the services within Gandalf's area of ownership and the APIs that power our client experiences. Through weekly work that presents complex and varied challenges, including AI-powered features, you will continue to become familiar with processes, patterns, and best practices. You'll regularly impact end users while acclimating to our best practices and pushing code through our continuous delivery release motions that ship to production several times a day.

Solidifying the foundation.

Beyond the first couple of months, you will grow into an autonomous operator, capable of architecting solutions to complex problems that are consistent with our existing patterns and best practices with minimal supervision. You will partner with cross-functional engineering teammates, as well as your product manager, designer, and engineering manager to help build execution plans for new features that support our product and business strategy. Rotation duration and team alignment is dependent on start date and evolving staffing and business needs in our growing company. We'll start this conversation with you and the Engineering leadership team on days 30-60 and target a 3-4 month rotation. As these details take shape, we'll stay consistent in aligning your talents with new challenges and opportunities that optimize your impact on the Engineering and Product orgs as well as the business.

Accelerate growth.

With solid foundational understanding gained from your rotations, you'll have opportunities to inform and affect change at the platform level while finding your team home. Through partnership with product and design across multiple teams, you'll be empowered to influence strategy and end-user experience. Complex product problems, technical challenges re
