• Bug Bounty & Vulnerability Triage: Help manage our Bug Bounty and Vulnerability Disclosure Programs, systematically triaging, validating, and reproducing reported flaws before routing them to the right engineering teams.
• DevSecOps Integration: Assist in implementing and maintaining automated security testing tools (SAST, DAST, SCA) directly within our CI/CD pipelines to catch vulnerabilities automatically.
• Participate in Threat Modeling: Partner with senior security engineers to facilitate threat modeling sessions and architectural reviews for new features and microservices using frameworks like STRIDE.
• Support AI & Security Automation: Support team initiatives in leveraging modern security automation and AI-driven tools to optimize vulnerability triage, code analysis, and daily security workflows.
• Track Vulnerability SLAs: Help track remediation progress against key metrics like Mean Time to Remediate (MTTR) and SLA Adherence %, working directly with developers to ensure timely fixes.
• Developer Enablement: Serve as a helpful partner for software engineers, providing guidance on secure coding standards, best practices, and secure library usage.

• Application Security Fundamentals: Solid foundational knowledge of web and mobile application security principles, common vulnerability types (OWASP Top 10), and basic web/API security architectures.
• Hands-On Coding Ability: Ability to read and understand code in at least one modern programming language (e.g., Java, Python, Go, or TypeScript) to help identify and fix security flaws.
• Vulnerability Triage & Validation: Experience reproducing application vulnerabilities (e.g., XSS, SQLi, IDOR, authentication bypasses) and using tools like Burp Suite or OWASP ZAP.
• DevSecOps & CI/CD Awareness: Basic understanding of modern CI/CD systems (e.g., GitHub Actions, GitLab CI) and how automated security scanners (SAST/SCA) integrate into developer workflows.
• Cloud & Container Baselines: Exposure to basic cloud computing principles (AWS, GCP, or Azure) and container concepts (Docker, Kubernetes).
• AI & Automation Curiosity: Eagerness to learn and utilize AI-driven tools (such as LLM coding assistants) to automate security scripts, triage tasks, and security analysis.
• Pragmatic Communication: Strong collaborative skills and an empathetic approach to partnering with software engineers to solve security issues without slowing them down.
• Будет плюсом: Experience participating in Bug Bounty programs (as a reporter or triager) or CTF (Capture The Flag) competitions; Familiarity with authentication/authorization standards like OAuth 2.0, OIDC, or SAML; Industry certifications focusing on foundational security skills (e.g., Security+, eJPT, or GWAPT)
