Job description

About The Role

The Lister team owns how property partners list, manage, and succeed on Apartment List — and it's one of the areas where product quality directly shapes whether renters find accurate, trustworthy listings. As a Senior Software Engineer II, you'll take ownership of core services and experiences on this team, working end-to-end from backend architecture in Kotlin and Ruby to frontend interfaces in TypeScript and React. You'll shape technical direction for problems that don't have a playbook yet, and you'll be a reference point for other engineers — through code reviews, design discussions, and the standard you hold for the work.
