About Us
Perk (formerly TravelPerk) is the intelligent platform for travel and spend management. 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.
We’re trusted by more than 10,000 companies worldwide, including Wise, On Running, Breitling, and Fabletics, and we’re tackling the 7 hours of lost productivity per employee each week, a $1.7 trillion problem.
Founded in 2015, Perk has grown into a global company of more than 1,800 people across 12 offices globally, with headquarters in London and Boston. We combine innovation, control, and simplicity to transform how businesses work and how people feel at work.
At Perk, we’re driven by our values, like being an owner, delivering a 7-star experience, and working as one team. We value curiosity, purpose, and mindset, not just knowledge, to unlock the power in your potential. Our talent team brings together leading minds from the travel and SaaS industries, representing over 70 countries. If you’re excited about having a real impact and shaping how millions of people experience work, we’d love you on the team.

At Perk, our Payments Experience squad owns the customer-facing layer of our payments product — how travellers and financial controllers set up payment methods, pay, receive refunds and credits, and access fintech add-ons. 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.
The Payments Experience team owns the moments that matter most to our customers: how they check out, how pricing is presented, how refunds are handled, and how the internal teams supporting them get their work done. We're looking for a Senior Engineer who wants to build products that people actually feel. The scope is deliberately end-to-end connecting directly to how customers perceive Perk, and how efficiently the business runs behind the scenes. 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.
How we work
You’ll join a cross-functional squad running two-week Kanban cycles, with standups, planning, refinements and retros. 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.
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 specifying features, writing and reviewing code, and automated AI PR review on every pull request. We also embrace agentic coding, using AI as an active collaborator, not just a prompt-by-prompt co-pilot. We expect candidates to use AI tools in our coding interviews.
Some examples of what it means to be a Senior at Perk
Shape the bigger picture. You’ll contribute to the payments roadmap alongside finance-focused PMs and your EM — defining not just how we implement payment flows, but how Perk’s payments experience should evolve across setup, paying, refunds and fintech add-ons to deliver what we call a ‘7-star travel experience’.
Architect for today and tomorrow. You’ll write design documents for significant changes to our payment systems, building financial state machines that are idempotent, auditable and correct by design. You’ll be a guardian of payment system quality — proactively identifying where we need to harden, simplify or invest in our payments stack before it creates customer impact.
Lead across boundaries. Payments Experience works closely with Payments Governance and Payments Platform. You’ll coordinate cross-squad deliverables, align stakeholders on payment architecture decisions, and contribute to engineering guilds. When something goes wrong in production, you’ll lead the response.
Raise the bar for everyone around you. You’ll mentor colleagues in payments engineering patterns, model what great financial system design looks like, and give thoughtful feedback in design reviews. You understand that for CFO-facing products, the bar for reliability and clarity is set higher than most.
