Built to tackle the time-consuming, manual work that gets in the way of real work, our tools automate everything from travel bookings to expenses, invoice processing, and more. By eliminating this shadow work that wastes hours, erodes morale, and saps innovation, we're on a mission to power real work, with real impact.

Founded in ****, Perk has grown into a general company of more than 1,800 people across 12 offices globally, with headquarters in London and Boston. Are you a Software Engineer who wants to own the payment experience that thousands of CFOs and travellers rely on every day?

You'll build the systems that handle real money movement for 10,000+ companies, where correctness isn't optional and the end-user experience directly shapes how customers feel about Perk.

We're looking for a Senior Engineer who wants to build products that people actually feel. Getting it right takes someone who thinks in systems but never loses sight of the person on the other end. If you care about the quality of what you ship, enjoy working closely with product and design to make hard problems feel simple, and want your work to have a visible impact on both customers and the people serving them - Payments Experience is a good place to be.

You'll have real ownership of the payments experience domain, working closely with finance-focused PMs, design and our broader payments group to shape what gets built and why.

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.
