You will own end‑to‑end onboarding systems, including partner integrations and data pipelines, shaping the architecture and design decisions.

The role requires deep product and system thinking, a track record of leading architectural design, and a commitment to maintainable code.

Qualifications

• Have deep command of software architecture and design patterns, and can explain when a pattern applies and when it does not
• Can reason through a system design in real time, defend it under scrutiny, and change position when presented with a better argument
• Have integrated with third‑party services and built resilient pipelines around unreliable external data

• Care about the long‑term maintainability of the codebase and advocate for refactoring and code cleanliness
• Use modern tools, including AI‑assisted development, while remaining the accountable author of every design decision you ship

• Design and evolve the service architecture for onboarding, including partner integrations, data pipelines, and the interfaces other AppFolio teams build against
• Lead design reviews, author technical proposals, and drive decisions to closure with clear trade‑off analysis
• Develop scalable, robust, and simple solutions to complex business problems, refactoring or starting fresh when it makes sense
• Define observability and alerting standards for the team's services so that every alert is actionable and every incident has a clear owner
• Mentor and guide other engineers through in‑depth code review, pairing, and healthy technical debate
• Work in a truly agile fashion to turn a large, unruly problem into thinly sliced deliverables and execute quickly against them
• Prioritize quality. Thoughtful test coverage is a given and any escalations from external stakeholders like our onboarding or customer care teams are handled and resolved swiftly. Exceptions should be exceptional.
