Security Engineer

Ensure product security—from designing new features to troubleshooting existing solutions.

At Kentico, we care about security, which is why we are currently expanding our Brno-based Security team with a new colleague. We have an established product, Xperience by Kentico, available in two variants – SaaS and private cloud. Both variants bring specific security challenges, and we need your help to tackle them. 

We believe in a comprehensive approach to security– from designing new features to identifying vulnerabilities in the existing solution. If that sounds appealing, let’s dive into the details. 


  • Type of employment: Full-Time
  • Start Date: ASAP
  • Technologies: .NET Core, React, OWASP
  • Language: English B2

What will you do?

  • You will help development teams design features to meet security standards. 

  • Once a feature is implemented, you will conduct a security review and identify vulnerabilities in the product. 

  • You will regularly conduct penetration tests of Xperience by Kentico. 

  • If a customer reports a security issue, you will analyze it, identify potential vulnerabilities, and assign a bug to the developers for resolution. 

  • If, in the future, you wish to develop further professionally, you can move towards a strategic role in product security as a Security Specialist. 

  • You will have an opportunity to tackle challenges in cloud security – ensuring not just product security but also the security of the infrastructure behind our Xperience by Kentico SaaS solution. 

    In short, you’ll get a tremendous opportunity for self-realization. 

What will you enjoy about this job?


  • Close collaboration with developers. Our developers are “just across the hall,” open to suggestions, and we maintain close contact during the entire development process. 

  • The ability to advocate any idea. We have a flat structure, and if something makes sense, we jump right into it. 

  • There are many paths to take, offering great variety. One day, you might conduct a code review, another day you could prepare educational materials for awareness training, handle customer security questions, perform pentests on our websites, or delve into cloud infrastructure hardening. 

  • We place a strong emphasis on proactive security. We aim to catch issues early in the development process, which also involves educating developers and QAs, performing threat modeling, and running other initiatives to prevent bugs. 

  • We understand that people have lives beyond work. You won’t face late-night calls here, as the entire team is based in the Czech Republic. We have a fantastic work-life balance. 

What do we expect from you?

  • Knowledge of OWASP methodologies and the ability to identify common vulnerabilities (OWASP TOP 10) in web applications. 

  • Hands-on experience with penetration testing – you can identify weaknesses before attackers do. 

  • The ability to automate processes using scripting languages like PowerShell, Bash, or Python. 

  • Familiarity with any OOP language. 

  • Basic knowledge of cloud environments (Azure, AWS, or Google Cloud) – you don’t need to be an expert, just have a fundamental understanding. 

  • Interest in staying up to date with industry trends – you are always learning and actively sharing your knowledge with others. 

What do we offer?

  • Use your Friday well: This is dedicated time for your personal development. You can use 20% of your time for innovations or further education that benefits the company.

  • Unlimited vacation: If you don’t use up your 5 weeks of vacation, you’re entitled to additional time off.

  • We offer an unlimited number of sick days.

  • Additional financial bonuses for life events such as weddings, childbirth, and paternity leave.

  • You can obtain various certifications fully covered by Kentico.

  • We also offer in-house exercise sessions, and of course, the usual benefits like meal vouchers, Multisport cards, extensive office refreshments, home office allowances, numerous company events, and more.

  • Are you interested? Get in touch, and we can arrange a meeting either in person at our office in Brno or online 😊
