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, 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 being part in understanding what our customers' pains are with our product team, 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 global platform.
Every day, tens of millions of dollars in bookings flow through systems the Billing team owns — and we're investing in the customer-facing side of that for the first time.
We're building out the billing experience: the pages our customers use to directly interact with collected and issued invoices. Working closely with our product designer and PM, you'll own this frontend experience end-to-end, from design handoff through to shipped, polished product. As the team's first dedicated frontend hire, you'll have real influence over how this area is architected from the ground up, and space to establish frontend practices and standards as the team's frontend footprint grows.
You'll be joining a team in the middle of significant technical change more broadly — re-platforming core billing flows to fault-tolerant, event-driven systems, scaling AI-driven invoice processing, and building out a tax engine used across trains, hotels, flights, and cars. You won't own that backend work directly, but you'll be embedded in a team tackling problems at real scale, and there's plenty of room to get involved beyond the frontend if that interests you.
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 to decide how to contribute to Perk’s company goals. We care about impact, and we trust our people to deliver it.
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. When something goes wrong in production, AI surfaces context across systems quickly. 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. The bar is understanding your code and owning what you produce. That reflects how we work every day.
Shape the bigger picture. You won't just build features, you'll refine the what to build and why. At Perk, senior engineers are expected to go beyond the technical solution and focus on the problem itself. You'll contribute to your squad's quarterly goals and long-term vision alongside your Product Manager and Engineering Manager.
Architect for today and tomorrow. When a big change is needed in how our frontend platform works, you'll be the one writing the design documents that lay the foundation. You'll become a guardian of your team's technical quality; spotting areas of investment, proactively managing technical debt, and making sure we don't let "busy work" crowd out the work that truly matters. At Perk, we believe in impact over effort: our customers see results, not the hours behind them. Your job is to make sure we're always investing our energy where it counts most.
Lead across boundaries. Your influence won't stop at your own squad. You'll communicate complex ideas across multiple teams, proactively identify who needs to be involved, and drive alignment across the broader organisation. Whether it's coordinating a cross-squad initiative, contributing to one of our engineering guilds (where engineers from different teams align on shared technical topics), or pairing with architects on solution discovery, you'll operate comfortably beyond your immediate team.
Raise the bar for everyone around you. Senior engineers at Perk are mentors, coaches, and bar raisers. You'll support less experienced colleagues through direct mentorship, thoughtful feedback during reviews, and by modelling what great engineering looks like in practice. You'll help Engineering Managers understand where the team needs to grow technically, and you'll use spaces like guild meetings, design doc reviews, and pairing sessions to lift the overall standard. At Perk, we are a team, the team's success is your success.
