About the Company

Perk (formerly TravelPerk) is the intelligent platform for travel and spend management.
Our tools automate everything from travel bookings to expenses, invoice processing, and more.
We are on a mission to power real work, with real impact.
Trusted by more than 10,000 companies worldwide.
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.
Driven by values: being an owner, delivering a 7-star experience, and working as one team.
Value curiosity, purpose, and mindset, not just knowledge.
Talent team brings together leading minds from the travel and SaaS industries, representing over 70 countries.
Excited about having a real impact and shaping how millions of people experience work.
Flights is one of Perk's fastest-growing engineering areas — expanding from one team to four since 2025, with more growth ahead.
The Flights domain is genuinely complex, involving more steps, suppliers, and failure modes than most travel products.
Our job is to hide that complexity and deliver a seamless customer experience.
We believe the best work happens when great people come together in small teams, with a shared sense of purpose.
AI is embedded in how we work and what we build.
AI spans the whole workflow: Notion, Jira, GitHub and Slack are AI-connected.
AI helps with specifying features, writing and reviewing code, and automated AI PR review.
AI surfaces context across systems quickly when issues arise in production.
We embrace agentic coding, using AI as an active collaborator.
We can help with relocation from anywhere in the world.
English is the official language at the office.
Perk is a global company with a diverse customer base.
We want to make sure the people behind our product reflect that.
