Your role in the team

  • Lead threat modeling and secure design reviews for high-risk changes, partner integrations, and payment flows.
  • Implement, tune, and enforce security gates in GitLab CI/CD (SAST, SCA, secrets scanning, and DAST) while minimizing developer friction.
  • Act as the primary technical owner for triaging, reproducing, and prioritizing findings from bug bounties, partner pentests, and automated scanners.
  • Work hands-on with the DevOps team to implement GCP organizational policies, IAM least-privilege architectures, and Cloud Armor (WAF/rate limiting).
  • Establish a security-champions network across engineering squads and leverage automation/AI-assisted tooling to scale code reviews effectively.

Our expectations of you

Qualifications

  • You read and write production code (Python, Go, TypeScript, Ruby, etc.) and deeply understand web frameworks, CI/CD, and Kubernetes.
  • You have deep knowledge of web and API security, specifically authentication/authorization models (OAuth2, JWT), rate limiting, tenant isolation, IDOR, and XSS.
  • You have strong cloud security fundamentals (GCP preferred), specifically regarding public exposure, secrets hygiene, and WAF rules.
  • You prioritize by real-world risk, propose trade-offs rather than demanding perfection, and communicate complex risks plainly to engineers and leadership.

Experience

  • You bring 5+ years in AppSec (or 3+ years plus a strong software engineering/web-pentesting background), with a track record of true ownership.
  • Bonus Points: You have experience securing high-volume, multi-tenant B2B APIs and utilizing AI tooling to accelerate triage and review.

What we offer

  • You will join a fast-paced travel tech company with a flat organizational structure.
  • You will have exciting opportunities, ownership, and responsibility and contribute directly to the success of the company.
  • You will join an international team of talented and driven people with a clear mission. Expect your colleagues to inspire, support and challenge you every day!
  • We have a flexible work policy with the option of working remotely and international opportunities arising as we continue to expand our global footprint - Our heart is in Berlin, but you'll find us across the globe.
  • You will get a competitive salary.
