Guesty is the all-in-one platform helping hospitality businesses around the world automate, optimize, and scale their operations. We’re a fast-growing global startup that’s transforming how the industry works — from guest experience to business growth.
With a powerful suite of features and integrations with 150+ industry partners — including Airbnb, Vrbo, Booking.com, Expedia, Google Travel, and many more — Guesty empowers property managers to deliver top-tier guest experiences while running more efficient, data-driven operations.
We’re proud to have over 900+ team members across 16 countries worldwide, all working together to build the future of hospitality technology.
If you’re looking to grow your career in a dynamic, global, and impact-driven environment, we’d love to hear from you.
We are looking for a Senior Cybersecurity Engineer to join our team.
As a Senior Cybersecurity Engineer, you are the architect and the guardian of our digital fortress. This role isn't just about reacting to threats; it’s about anticipating them, building resilient systems, and mentoring the next generation of defenders. You will bridge the gap between high-level security strategy and hands-on technical execution.
The Ideal Candidate is someone who thinks like an attacker but builds like an engineer. You don't just find a hole; you understand the systemic reason it existed and fix the process. You can explain a complex "Man-in-the-Middle" attack to a CEO without making their head spin, and you stay calm when the "Critical" alerts start firing on a Friday afternoon.
Proactiveness as a way of life - always think what the next attack vector will be, and where we should invest our efforts to prevent the next attack.
Success in this role is measured by a reduction in Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR), as well as the successful hardening of our CI/CD pipelines.
