Red Team Operator

Are you an experienced red team operator? Well, at NVISO we might be looking for you and we’d love to have a chat!

Who are we?

It all starts with the mission: NVISO is here to protect European society from potentially devastating cyber attacks! This means we offer cyber security services to private and governmental organizations to help them better prepare for, prevent, detect and respond to cyber security incidents.

So what does this mean in practice? What do we actually do?

  • Defining the overall cyber security strategy (e.g. building out and delivering an awareness program)
  • Offensive security services such as red teaming and penetration testing
  • Building and securing cloud-native architectures
  • Emergency support such as incident response / forensics when organizations are breached
  • Managed services such as Managed Detection & Response and Vulnerability Management
  • Highly tailored / niche cyber security work in for example ICS environments

The list is not exhaustive and our very own NVISO Labs is continuously investigating new possible services or new ways to tackle the rapidly changing problems in cyber security!

As a proud European company, we currently have offices in Belgium (Brussels) and Germany (Frankfurt and Munich). Technically, we are present in many more towns and cities, as our people often work from home too.

All of this is built on four fundamental values that define who we are: We are Proud, We Break Barriers, We Care and No BS!

What will you do?

As a red team operator you will :

  • Execute target-driven engagements, ranging from objective-based penetration testing to red/purple teaming and even full-fledged TIBER exercises
  • Bring these engagements to fruition, from reconnaissance to action on objectives by emulating tactics, techniques, and procedures across the (Unified) Kill Chain
  • Help clients in different sectors improve their security posture in terms of prevention, detection, and response by providing tailored recommendations
  • Fuse technical and non-technical skills to communicate with stakeholders on different levels
  • Perform research and development to continuously improve our tradecraft and methodology


You are passionate about cyber security and consider the following to be applicable to you:

  • Bachelor’s or Master’s degree 
  • 2+ years of experience executing red team engagements
  • Good understanding of “the basics”: different platforms, operating systems, software, communications, and network protocols
  • Knowledge of the Unified Kill Chain, MITRE ATT&CK, and other principles relevant to adversary emulation
  • Experience with post-exploitation using command and control frameworks, in particular those used by real adversaries, such as CobaltStrike
  • Purple team experience is a plus
  • Experience with payload crafting is a plus (C++/C#, Win32 API, AV/EDR evasion, etc.)
  • Proven skillset through relevant certifications and courses (CRTP, CRTE, PACES, CRTO, OSEP, OSCE, etc.)
  • Positive, team and mission-oriented attitude
  • Excellent communication skills, both verbal and written (English required, Dutch or French desired)
  • You are eligible for NATO CLEARANCE (see HERE for more information)
