The posting

ENJOY Gaming is a software provider focused on creating high-quality digital entertainment experiences, including Slots and Live Games. Our team brings together experienced professionals in game development, product, and design, driven by a passion for innovation and quality.

At ENJOY Gaming, we value ownership, excellence, and drive. These principles shape the way we work, collaborate, and build products.

Join us and be part of our innovative journey in the gaming world!

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 in application security, offensive security or security-focused software engineering, with a strong hands-on web/API focus
  • Strong secure code review in TypeScript/Node.js (NestJS); able to read and review C#/.NET
  • Deep knowledge of Node.js-specific bug classes: prototype pollution, ReDoS, SSRF, ORM/query injection (TypeORM/Prisma/Mongoose), mass assignment and DTO validation bypass, unsafe deserialization, npm supply-chain risks
  • Manual web and API testing beyond scanners: broken access control (IDOR/BOLA), business-logic flaws, race conditions and idempotency issues in financial flows (wallets, bets, bonuses, payouts)
  • Solid understanding of authentication and authorization: OAuth 2.0/OIDC, SAML, JWT, session management, signed third-party callbacks (HMAC), common cryptographic misuse
  • Threat modeling (STRIDE or similar) and secure design reviews of new features before implementation
  • Hands-on with SAST/SCA/DAST/secrets scanning in CI (e.g. Semgrep/CodeQL, Trivy/Dependabot, Burp Suite/Acunetix, Gitleaks): tuning, custom rules, false-positive reduction
  • Understanding of security in event-driven architectures (Kafka, Redis/BullMQ, Pub/Sub): trust boundaries, message replay/poisoning, service-to-service authorization
  • Able to write and ship production-quality fixes in TypeScript/NestJS during incidents, and to verify developers’ fixes through diff review and retesting
  • Uses AI/LLM tools effectively for code review and vulnerability hunting, and critically validates their output
  • Turns findings into clear, prioritized, actionable remediation for developers

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 (Acunetix, Burp) and SAST(Semgrep, CodeQL)
  • 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
  • Remote Work & Core Hours: full-time remote role (8 hours + 1 hour lunch) with mandatory availability between 9:30 and 17:30 CET for team collaboration
  • 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
  • Professional Development Support: reimbursement for courses, trainings, and certifications
  • Well-being Perks: support for language classes, sports, massages, or life coaching

Please note that feedback on your application will be provided within two weeks if a positive decision is made regarding your candidacy.

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
