As a Senior Software Engineer on the Finance Experience team, you'll play a central role in delivering the systems that power seamless, automated expense reconciliation for Perk clients.
The team's mission is ambitious: to reconcile 100% of travel expense data for every client through a fully automated, accurate, and effortless accounting experience - eliminating manual effort for finance teams. You'll work across the full stack on features spanning employee reimbursements, expense capture, ERP integrations, supplier invoicing, and integrations with third‑party expense platforms like Pleo and Ramp.
Through close partnership with finance, compliance, and cross‑functional engineering teams, you'll help ensure that every step in the financial reconciliation journey works seamlessly.
Are you a Senior Software Engineer who thrives on real ownership?
This means taking responsibility for the entire lifecycle of a feature, from understanding customer pains with the product team, design documents, coding to deployment, and measuring impact.



Engineering excellence here is measured by the reliability and simplicity of the systems you build to power a integral platform.
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. We care about impact, and we trust our people to deliver it.
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 specifying features, writing and reviewing code, and automated AI PR review on every pull request. When something goes wrong in production, AI surfaces context across systems quickly. The bar is understanding your code and owning what you produce.
