📋 Description

• Getting to know teammates, technology, and tactics. Your first day, you'll pair with your manager and a colleague to set up your local environment and ship a bug fix — using our agent workflows end to end. The following 29 days involve connecting with engineers across the professional experience and Reporting to understand how we prioritize, plan, build, and deliver value on OurFamilyWizard. You'll get immersed in daily and weekly agile rituals, the API guild, and our internal skills and plugins ecosystem. By the end of your first month, you'll be running your own spec-to-ship cycles inside Pro Core's domain — the professional user experience and Reporting. • Try, learn, ship. By day 60, you're operating our SDLC from planning through production release — authoring specs, orchestrating multi-file agent work, and reviewing outcomes rather than lines. You'll have a broad understanding of our backend architecture and deeper expertise in the services Pro Core owns and the APIs powering both the professional user experience on OurFamilyWizard and our Reporting product. You'll ship to production several times a day and start contributing skills and plugins that the rest of engineering can reuse. • Solidifying the foundation. Beyond month two, you grow into an autonomous operator — architecting solutions to complex problems, defining specs sharp enough that agents can execute them, and calibrating when a problem needs human hands vs. agent iteration. You'll partner with cross-functional teammates and leadership to shape execution plans for new features. We'll start conversations about long-term team alignment between days 30–60 and target a 3–4 month rotation. • Accelerate growth. With foundational understanding gained, you'll inform platform-level change and find your team home. Complex product problems, scale and modernization challenges, and the frontier of AI-integrated product experiences will establish you as a subject-matter expert and expand your ownership.

🎯 Requirements

• 5+ years of production software engineering, with demonstrable depth in a statically typed backend language (Java preferred; Kotlin, C#, or Go acceptable with strong backend systems experience) • Fluency in spec-driven development: you can point to specs you've authored and features an agent shipped from them • Daily hands-on use of AI coding agents (Claude Code, Cursor, GitHub Copilot Agent, OpenAI Codex, or similar) as your primary development interface — not as autocomplete • Experience building and using skills, plugins, or custom agent workflows (MCP servers, Claude skills, Cursor rules, Copilot extensions, or equivalent) that your team or others reuse • Reviewer's judgment on AI-generated code: you can articulate failure modes, catch hallucinations, and decide when to accept, iterate, or take the keyboard back • Strong knowledge of relational databases, ORM technologies (Hibernate or equivalent), and API design • Object-oriented analysis and design using common design patterns • Proven experience delivering software from inception to production in a cross-functional team that ships continuously to production.
