Are you a Software Engineer who thrives on real ownership?

At Perk, we know that we feel most fulfilled when we can own the problem and the solution. This means taking responsibility for the entire lifecycle of a feature, from understanding what our customers' pains are with product teams, design documents, coding to deployment, and measuring impact. You will see how your technical decisions move the needle for our customers daily.

We prioritize autonomy and pragmatism, giving you the space to solve complex problems without unnecessary friction. Engineering excellence here is measured by the reliability and simplicity of the systems you build to power a general platform.

Join the Billing team

The billing team owns tax determination, invoice issuance, invoice collection, and deferred payments. Right now the team is in the middle of its most significant technical work: migrating tax determination to a third-party integration, rearchitecting invoice issuance for async processing at scale, and automating a previously manual invoice collection process into a fully self‑serve service,



with AI at its core. There's also a growing stream of product‑facing backend work as we look to improve the end‑to‑end billing experience. If you want real ownership of a domain that matters, in an engaged team that values teamwork, this is the team.

How we work

At Perk, we believe the best work happens when great people come together in small teams, with a shared sense of purpose. You'll join a cross‑functional squad where you have real ownership of a piece of Perk’s domains, a genuine say in what gets built, and the autonomy to make it happen. Each team decides how to contribute to Perk’s company goals. We care about impact, and we trust our people to deliver it.

AI at Perk

AI is embedded in how we work and what we build. On the engineering side, it spans the whole workflow: our Notion, Jira, GitHub and Slack are AI‑connected so you get up to speed fast, and day‑to‑day it helps with
