Senior Java Engineer

In Tandem is a company that builds technology to help families manage everyday routines and transitions. As a Senior Java Engineer, you will contribute to features that simplify life for families, collaborating with cross-functional teams to develop robust backend services and APIs using modern technologies, including AI-powered features.

Responsibilities:

• 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

Requirements:

• 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
• 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
