Sr. Software Engineer - Resident Onboarding

App Folio is more than a company. We're a community of dreamers, big thinkers, problem solvers, active listeners, and multipliers. At every opportunity, we set the pace while delivering innovation built to carry real estate into the future. One in which every experience feels effortless, yet meaningful. Where customers are empowered to take on any opportunity. We show up as one team, connected by our values to be a force for good.

Because together, we have the power to create extraordinary outcomes for our customers, our communities, and ourselves.

Moving is one of the most stressful events in a person's life. Between signing a lease and settling in, a new resident has to set up utilities, secure renters insurance, and coordinate with a property team that is juggling dozens of other move‑ins. Most of that work is still manual, fragmented across vendors, and easy to get wrong. We are hiring a Senior Software Engineer to join the Resident Onboarding team and become a technical domain expert in making that transition effortless.

This is a domain that gets complicated quickly. Utility providers vary by address and change without notice. Insurance requirements differ by property and jurisdiction. Partner systems are unreliable, data arrives incomplete, and every gap surfaces as a phone call to a property manager on move‑in day. We combine automated research, partner integrations, and careful data modeling to close those gaps before the resident ever notices them.

Our systems serve every new resident on App Folio's Real Estate Performance Management platform.

This is an ideal opportunity for an engineer who thinks in systems, cares about the shape of a codebase years from now, and wants to set technical direction on a small, empowered team. You will be the engineer others look to when a design decision is hard.

• Build a deep understanding of the resident onboarding domain, enabling you and your team to truly own it end to end
• Design and evolve the service architecture for onboarding, including partner integrations, data pipelines, and the interfaces other App Folio 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.

• 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
• Write designs clearly enough that engineers outside your team can build against them
• 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
• You don’t need Claude. Claude needs you.

• 5+ years of professional experience building…
