Senior Backend Engineer

About the role

This is a senior engineering role for someone who has already made the shift to AI-native development. Your day is built around writing specifications, orchestrating agents, and reviewing the features they deliver. Your output is measured in features shipped and outcomes validated.

Responsibilities

• Get 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.
  • Solidify 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.
  • Accelerate growth.
    • We'll start conversations about long-term team alignment between days 30–60 and target a 3–4 month rotation.
    • 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

  Qualifications

  • Java/Spring/Spring Boot background (our primary stack)
  • Full-stack range across React/Web, iOS, or Android on top of backend depth
  • Experience with Docker and Kubernetes
  • Experience with Atlassian tooling for CI/CD (Bitbucket Pipelines, Jira, Confluence)
  • Experience with Confluent Cloud (Kafka)
  • Experience with iterative, agile-based software delivery
  • Experience working across multiple product teams or in rotational capacities
  • Experience in family technology, legal technology, or complex platform environments
  • Contributions to shared AI-native tooling in your current organization — skills, plugins, prompt libraries, or evaluation harnesses that outlived a single project

  Skills

  • AI-native operator
  • Calibrated, not credulous
  • Grounded in systems
  • Curious explorer
  • Adaptable relationship builder
  • Champion of inclusion and bridge-building collaborator
  • Low ego, high integrity
  • Pragmatic optimizer and growth-oriented learner
