As an Application Security Engineer, you’ll work closely with Trendyol’s engineering teams to enhance application security across our platforms. You’ll perform web and mobile security testing, validate fixes through code reviews, and provide expert guidance on secure coding practices. In this role, you’ll support our bug bounty program, develop custom security tools, and help drive root-cause analysis and remediation. We’re looking for a collaborative, open-minded teammate who is eager to improve, communicate clearly, and promote security best practices throughout the organization.

A hybrid working model with flexibility — a schedule that helps you find the right balance between flexibility and team bonding, including work-from-abroad opportunities and a summer working model.

A customizable FlexBenefits budget — Adjust your daily meal allowance, choose your health insurance package (and extend it to your spouse or children), and pick from additional benefits like fuel support or Trendyol shopping credits.

Comprehensive wellbeing support — Take advantage of our extended health package, which includes annual mini health screenings, access to location-based in-house doctors, psychologist and dietitian support, and HPV vaccination coverage.

Personalized training allowance and learning opportunities — Use your annual budget for any training or conference of your choice, explore our Learning Management System (LMS) anytime, and join in-person learning sessions offered throughout the year.

Responsibility from day one — Take full ownership from the start in a culture where every voice is heard and valued.

A diverse, international team — Collaborate with global peers across our offices in Berlin, Amsterdam, Dubai, and beyond, in a startup-spirited and collaborative environment.

Opportunities to grow with the best — Tackle meaningful challenges, develop through hands-on experience, and grow with the support of expert guidance and global mentoring.

Meaningful connections beyond tasks — Be part of team rituals, events, and social activities that help us stay connected and inspired.
