Are you a Software Engineer who thrives on real ownership?
We value engineers who take responsibility for the full lifecycle of a feature—from understanding customer pain with product teams, to design, coding, deployment, and measuring impact. You will own decision‑making that directly moves the needle for our customers each day.
Join the Billing team
The billing team owns tax determination, invoice issuance, collection, and deferred payments. Current focus includes migrating tax determination to a third‑party integration, rearchitecting invoice issuance for async processing, and automating invoice collection with AI. There is also growing front‑end work to improve the end‑to‑end billing experience.
How we work
Cross‑functional squads own domain units, set priorities, and decide how to contribute to company goals. Teams work in person three days a week and embrace autonomy and pragmatism. We trust our people to deliver impact and encourage collaboration across squads and guilds.
AI at Perk
AI is embedded throughout our workflow—helping specify features, review code, and surface context quickly. Candidates are expected to use AI tools during coding interviews, demonstrating ownership of their code.
