A large gaming/ gambling firm in the Balkans (Serbia etc) are looking for an Application Security Engineer with Java to work remotely out of a Balkans country paying €80-100,000 plus bonus.
My client require a security-focused software engineer who can spot and fix vulnerabilities, guide developers on safe coding, and ensure applications stay secure throughout their lifecycle — essentially, someone who acts as the “bodyguard” for the company’s software.
This role is for a tech professional who makes sure software applications are secure from hackers and vulnerabilities. You’ll be responsible for protecting both web and mobile apps throughout their development and deployment.
Key responsibilities :

- Scan and test for security problems: Use automated tools (SAST/DAST) and manual methods to find weaknesses in code and apps.
- Penetration testing: Try to “hack” the apps in a controlled way to uncover vulnerabilities before bad actors do.
- Monitor and fix vulnerabilities: Keep an eye on new threats, outdated software, or weak dependencies and ensure they’re addressed quickly.
- Collaborate with teams: Work closely with developers, DevOps, and others to improve overall security.
- Stay up to date: Track the latest security threats, software versions, and best practices, recommending updates and fixes.
- Support secure deployment: Ensure apps remain secure whether running in the cloud or on company servers.
- Participate in reviews: Be involved in code reviews, risk assessments, and planning to spot security risks early.
Who they’re looking for:
- MUST be able to get to Belgrade, Serbia for a few days every 3 months. Flights and accommodation are paid for!
- Education: Degree in Computer Science, Electrical Engineering, or similar.
- Experience: At least 5 years in application security, DevSecOps, or related areas.
- Tech skills:
- Strong Java skills and experience with frameworks like Spring/Spring Boot.
- Hands-on with security testing tools and CI/CD integration.
- Knowledge of web and mobile security threats (OWASP Top 10, SANS Top 25).
- Familiar with HTTP/HTTPS, authentication, and secure API design.
- Programming/scripting skills in Python, JavaScript, or Shell.
- Mindset & soft skills: Honest, accountable, constantly learning, and able to communicate well in English.
- Bonus: Security certifications like OSCP, OSWE, OSCE, or GPEN.
