Job description

Distribusion

Distribusion is the world's leading ground transportation marketplace and gives travellers seamless access to ground transportation online, from search to ticket purchase.

We are one of the fastest growing startups in travel, backed by leading venture capital investors including TQ Ventures, Lightrock, Creandum, and Northzone, and are headquartered in Berlin, Germany. Following our recent $80m Series C funding, we are ready to push beyond.

Senior Product/Application Security Engineer (Greenfield Opportunity)

We are looking for our first dedicated Senior Product/Application Security Engineer to build our AppSec practice from the ground up. This is a greenfield opportunity with a real attack surface: public partner-facing APIs and payment flows. You will own secure development, define what gets reviewed, implement security gates, build the "paved road" for ~150 engineers, and see the impact of your work in production within weeks.

What you will do:

• 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.
• Own vulnerability management end to end: a risk-ranked backlog, remediation SLAs, an escalation path, and closing findings together with the teams.
• Scope and coordinate the annual external penetration test and produce secure-development evidence for PCI-DSS and ISO 27001.

Workplace and Culture

We are a remote-first company with teams located around the Globe and a HQ in Berlin. 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.

Qualifications

Who you are: You bring 5+ years in Product/Application Security (or 3+ years plus a strong software engineering/web-pentesting background), with a track record of true ownership. 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 have run threat modelling and secure design reviews on real systems (STRIDE or similar). Hands-on with SAST/SCA/secrets scanning in CI (Aikido, Semgrep, Snyk or similar). You prioritize by real-world risk, propose trade-offs rather than demanding perfection, and communicate complex risks plainly to engineers and leadership.

Bonus Points

• You have experience securing high-volume, multi-tenant B2B APIs and utilizing AI tooling to accelerate triage and review.

What you can expect

You will get a competitive salary. Our hiring team for this role: Your Talent Partner (TP) and point of contact is Lorena Rebenciuc, and the Hiring Manager (HM) is Ilya Isakov.
