As a Middle+/Senior DevSecOps Engineer, you will:

Vulnerability Management — full lifecycle:

• Launch, monitor, and analyze scanning results across code, dependencies, containers, and IaC.
• Triage findings and prioritize them based on real risk, not only CVSS.
• Perform hands-on remediation: update dependencies, apply patches, harden Docker/K8s/IaC configurations, and create pull requests in repositories without involving developers.
• Coordinate complex fixes with development teams, monitor SLA compliance, and verify remediation through re-scans.
  
  

Security in CI/CD:

• Administer and maintain already integrated SAST, DAST, SCA, and Secret Scanning tools.
• Process security alerts and investigate false positives.
  
  

Monitoring and Operational Security:

• Review logs, work with existing SIEM/Wazuh rules, and escalate incidents to the SOC when needed.
• Tune existing WAF/Cloudflare rules according to established instructions and procedures.
  
  

We value specialists who:

• Have hands-on experience with vulnerability management, including working with scanners such as Trivy, Snyk, SonarQube, Semgrep, OWASP ZAP, Gitleaks, and similar tools, and understand how they work.
• Have practical remediation skills: can independently update a package, modify a Dockerfile, make changes to Terraform/Helm, or create a basic code PR in Python, JavaScript, or another language.
• Are confident with Bash and Python for automating routine tasks and interacting with scanner APIs.
• Have practical experience with Docker and Kubernetes and understand CI/CD pipelines, such as GitLab CI, GitHub Actions, or Jenkins.
• Have a basic understanding of infrastructure and networking: Cloud (AWS/GCP/Azure), IAM, TLS, DNS, network segmentation, and firewall principles.
• Have strong communication skills and can clearly assign tasks to developers, explain the criticality of a finding, and justify the need for remediation.
  
  

Will be a plus:

• Experience with an existing secrets management infrastructure such as Vault will be a plus.
• Have a basic understanding of SIEM, including log collection and reading existing detection rules.
• Experience with Cloudflare (WAF/rate limiting) at the level of maintaining existing configurations will be a plus.
• Understand OWASP Top 10 and can explain the nature of vulnerabilities to developers.
