We’re looking for a sharp Application Security Engineer to join our team and act as the technical guardian for our games and platforms. If you have an attacker's mindset but know how to build and defend alongside engineering teams, this role is for you. In this position, you won’t just be sending reports to the teams or management. You’ll be diving deep into web and desktop applications, hunting down game-level vulnerabilities, and collaborating closely with our Architects, Studio, Slots, and Platform Developers to engineer more resilient systems.

What we're looking for:

• 5+ years of Application Security Engineer experience

• Background in red teaming, penetration testing, application security, and software development

• Able to independently find vulnerabilities in web and desktop applications, triage them, and, where needed, fix them

• Solid grounding in data structures, algorithms, and systems architecture designs

• Previous security testing experience with Kafka/Redis/BullMQ/PubSub as message/streaming tools

• Codes independently, can navigate unfamiliar web application frameworks

• Experience using AI tools to aid with vulnerability hunting

• Comfortable talking to developers and turning findings into practical, actionable advice

Nice to have:

• CRTO, OSCP, or OSWE certifications or similar

• Knowledge of Cloud Platforms (GCP/AWS)

• Understanding of CI/CD pipelines

• Hands-on experience with Trivy, Nessus, Acunetix, or Wiz

• Experience in iGaming or another regulated industry

What You Will Do:

• Own and maintain our application security pipelines: SCA (Github/Trivy), DAST (Nessus, Acunetix, Wiz), and SAST

• Triage findings from these tools and drive them to remediation

• Perform penetration tests on new platform features, new internal applications, and new slots and live games

• Run basic red team activities, including leaked credential reviews and external attack surface audits

• Review complex auth flows with various third parties for cryptographic and security issues

• Review/Triage application code for security issues ( 85% NestJS / 15% .NET )

• Own security risk in existing code and applications

• Act as the application-level security expert during incident response and be ready to deliver hotfixes yourself when needed

• Prepare our quarterly SAST/DAST vulnerability scan reports for stakeholders/regulators and take part in audit meetings

• Own the Secure Coding and Application Security areas of our ISMS

• Meet regularly with development teams, learn about upcoming features early, and advise on secure design

What We Offer:

• Competitive Salary in EUR: with annual performance reviews to recognize your growth

• Flexible Remote Work: balance productivity and comfort

• Comprehensive Benefits: including medical insurance, psychologist support, and Polish, Slovak-speaking clubs

• Generous Paid Time Off: 20 working days of paid vacation, plus 10 additional paid days off, 10 paid sick days, and all national holidays in your country
