Job Description

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.

Responsibilities:

Responsibilities:

Security Architecture & Design: Lead the design and implementation of robust security infrastructures across cloud (AWS/Azure/GCP) and on-premise environments.
Incident Response & Forensics: Act as a Tier 3 escalation point for security breaches. Lead post-mortem analyses to ensure "lessons learned" become "vulnerabilities patched."
Engineering & Automation: Develop automated scripts (Python, Bash, or PowerShell) to streamline security monitoring and incident response workflows.
Vulnerability Management: Oversee continuous scanning, penetration testing coordination, and the remediation of discovered weaknesses.
Compliance & Governance: Ensure our systems align with industry standards such as ISO 27001, SOC2, NIST, or HIPAA.
Mentorship: Provide technical leadership to junior engineers and conduct security awareness training across the organization.

Requirements:

Requirements:

At least 5 years of experience as a cybersecurity engineer in a cloud-based environment, with vast hands-on experience

Cloud Security: IAM policies, KMS, CloudTrail, Container Security (Kubernetes/Docker).
Tools: SIEM (Splunk/Sentinel), EDR (CrowdStrike/SentinelOne), Wireshark, Metasploit.
DevSecOps: Integrating security into CI/CD pipelines (GitHub Actions, Jenkins), managing the bug bounty program, validating the findings, and working with the teams to resolve the findings.
Compliance and GRC: Experience with audit processes such as SOC2 Type 2 and PCI-DSS, using compliance management platforms (Vanta / Scytale)
Certifications: CISSP, CISM, CEH, or AWS Certified Security Specialty.
