Senior Backend Engineer, Java
Department: Engineering
Employment Type: Permanent - Full Time
Location: Remote USA - In Tandem
Compensation: $120,000 - $140,000 / year
Description
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 related to scale and modernization, and AI integration opportunities will help establish you as a subject matter expert, expand your impact and ownership, and continue your growth as an engineer in your ongoing role within the organization.
Who you are:

• Curious operator. You value the variance in challenges a cross-functional team encounters and embrace unexpected hurdles with a mindset that seeks to understand the landscape before charting a course towards a solution. In a rotational role, you thrive on switching between different codebases, team priorities, and problem domains, viewing variety as an opportunity to broaden your expertise.
• Adaptable relationship builder. You embrace change and ambiguity as opportunities rather than obstacles, thriving in dynamic environments while proactively establishing trust and rapport with new team members across different rotations.
• Confident craftsperson with an AI-first approach. You bring AI into every problem from the start - not as a shortcut, but as a force multiplier. For straightforward challenges, a well-framed prompt gets you to a clean outcome fast. For complex ones, your depth of platform knowledge lets you guide AI tools precisely, asking better questions and exercising sharper judgment on what comes back. When you're operating in unfamiliar territory, you know how to turn that around: use AI to spelunk the system, surface context, and help map the best path forward before you commit to one. You're fluent in code generation, debugging assistance, and architectural exploration - and you know how to calibrate your approach, so AI impact scales with problem complexity. You view challenges and feedback as development opportunities, growing your craft through human mentorship, hands-on experience, and the expanding frontier of what AI-assisted engineering makes possible.
• Champion of inclusion and bridge-building collaborator. You want everyone on the team to have a voice and are open and eager to hear everyone's thoughts, helping to guide teams to good solutions. You naturally think about how your work connects to other parts of the platform and get excited about facilitating conversations that span multiple teams.
• Low ego, high integrity. You value doing what's right over being right. You pivot when a better path forward arises in order to meet technical and business needs and are comfortable saying something when a course correction is needed.
• Pragmatic optimizer and growth-oriented learner. You identify when something's harder than it should be, articulate why change is needed, and affect change through incremental improvements. You see each rotation as a masterclass in different aspects of the platform, motivated by accelerated learning curves and viewing temporary discomfort as the price of exponential growth.

What you bring:

• 5+ years of Java development experience
• Analytical mindset and good problem-solving skills
• Experience in the Spring Framework and Spring Boot
• Proven experience delivering software applications/features from inception to shipping within a cross-functional team environment
• Object Oriented analysis and design using common design patterns
• Excellent knowledge of Relational Databases and ORM technologies (Hibernate)
• Experience with AI development tooling and integrations (Claude Code, GitHub Copilot, OpenAI Codex, Cursor, or similar AI-powered CLI's and IDE's)
• Proficiency with AI-assisted development workflows including code generation, debugging assistance, automated testing, documentation creation, and architectural exploration
• Ability to architect AI-integrated solutions and make informed decisions about how to leverage AI technologies in software development

What would be great to have:

• Experience with Docker and Kubernetes
• Experience with Atlassian products for CI/CD (Bitbucket Pipelines, Jira, Confluence)
• Experience with Confluent Cloud (Kafka)
• Experience with writing and maintaining tests
• Experience with iterative, agile based software delivery processes
• Experience working across multiple product teams or in rotational capacities
• Experience in family technology, legal technology, or complex platform environments
• Strong judgment in AI-assisted development - effectively leveraging AI tools to accelerate engineering across all domains while maintaining code ownership, quality standards, and using AI capabilities to enhance rather than replace engineering rigor.
