Security Engineer (m/f/d)

Full time/ Location: Sofia, BG

Founded in early 2017, WebPros brings together widely used web hosting, billing automation, infrastructure, server management, and online marketing software solutions. Constantly adding new brands and products to its portfolio, in its current formula, WebPros comprises Plesk, cPanel, WHMCS, SolusVM, NIXStats, XOVI, Koality, and Sitejet. Overall, we power more than 85 million websites on more than 900,000 servers worldwide.

Our global team is made up of 600+ tech-loving professionals with offices around the globe. You will join a dynamic and fast-paced environment and work with cross-functional teams to design, build, and roll out products that deliver the company’s vision and strategy.

Our team focused on the analysis of products and services from a security perspective. We are conducting threat modeling meetings with development teams, performing reviews of source code, and discussing security aspects of product features. This means we are not producing changes in the code itself but aim to find vulnerabilities, perform risk assessments and provide all the necessary information to our development teams. Currently, we are working on introducing DevSecOps practices in the development workflow. We are working with a private bug bounty program and external auditors.


  • Monitoring and analysis of vulnerabilities in the used libraries and external components.
  • Integration of DevSecOps tools and practices for the product and the services (SCA, SAST, DAST).
  • Risk analysis and threat modeling.
  • Code analysis and external testing of the product in order to find vulnerabilities and weaknesses.
  • Work with external auditors and the Bug Bounty program.


Language Skills – Proficient Speaker


  • Three years of development experience.
  • Good system knowledge of Linux and security aspects of the system.
  • Understanding what vulnerabilities are, how they occur, and how to prevent them.
  • Understanding TCP/IP and work principles of DNS, FTP, SMTP, HTTP, and HTTPS.
  • Understanding TLS, cryptography.

Would be nice if you have an experience with:

  • Experience of working in a similar position.
  • Experience in DevSecOps tools and practices.
  • Experience in development in any programming language and ability to understand somebody else’s code (PHP, Go, Javascript, Python, Bash).
  • Experience in working with cloud systems (AWS, Google Cloud).
  • Experience in Docker and Kubernetes.


  • Spirited, intelligent, quirky, friendly, adventurous – Plesk employees have been called all of these things, but with our varied skill sets and personalities, we defy labels.
  • We are a tight-knit team that constantly challenges and encourages one another. Best of all, we sincerely believe in the value of the work that we do. And with 20 years under our belts — we’re not looking to slow down anytime soon.
  • Enjoy full integration from day one and continuous feedback.
  • Work with a cool team and enjoy an open-door policy on all levels.
