OT Security Junior Consultant (Student Assistant/Part-Time)

Ikon: Pil

Kickstart your career and gain practical experience with IT security in an organization where security is paramount.

Imagine yourself immersing in network traffic gathering, automation, and lab tests in a professional OT environment.

Do you want to come on board?

We are a team of 19 analysts, architects, and advisors specializing in IT security – five of us are working in our SOC and PenTest Team.

Our work spans red and blue team disciplines, including security testing, consulting, monitoring, threat intelligence, and incident management.

Our mission is to make DSB resilient to modern threats by offering practical advice and solutions that balance security with organizational needs.

Teamwork is key - we share knowledge, support each other, and collaborate daily on incidents, technical setups, and architecture. You'll join an environment where we learn, grow, and step up when action is needed.

Working at DSB as a Student Assistant has been an incredibly rewarding learning experience. I've developed both professionally and personally, learning how to collaborate effectively within a team to achieve shared goals.

The flexible work schedule allows me to balance my studies while taking on engaging tasks at work. The variety in age and experience in the team contributes to a supportive and welcoming work environment.

Says Benjamin, Student Assistant on the team

About the job

We imagine that you work approx. 10-15 hours a week. We will coordinate your working hours together, considering your exam periods and other obligations.

You can get a free DSB train pass for work and personal use.

As an OT Security Junior Consultant in the Cybersecurity Team, you will contribute to protect the IT and OT infrastructure.

A typical working day might start with updating the documentation for a recent security visit, where you organize photographs and notes about equipment and functionality.

Later, you can dive into network traffic analysis, where you perform baseline recordings and help the team identify normal operations.

After lunch, you plan a tabletop exercise that simulates realistic threats, or test scripts in Python to optimize our processes. Before going home, you assist your colleague with their current task.

You will also touch upon

  • architecture and network diagrams
  • logs from monitoring tools
  • PLCs in our OT laboratory
  • scripting languages (e.g. Bash & Python)
  • ad hoc tasks assisting the team

Who are you?

We are looking for someone who has a genuine interest in cybersecurity.

As a person you are thorough and focused on finding solutions. You are curious about new perspectives and ready to take initiatives.

Furthermore, you are ready to collaborate and engage in interdisciplinary contexts.

Professional qualifications

  • You are currently pursuing an academic degree in cybersecurity, IT, computer science, electrical engineering, or similar
  • You have a basic understanding of OT/ICS environments and cybersecurity principles
  • You are familiar with tools such as Wireshark, network miner, tcpdump, or similar for network analysis
  • You have experience with scripting languages such as Python or PowerShell

What can DSB offer you?

All our students, interns, and recent graduates are invited to join our Young Professionals' Network - an internal network, managed by its members and supported by HR.

This is where you meet for socializing, business inputs, and professional discussions.

You can look forward to

  • Developing your capabilities and skills
  • Flexible working hours and the option to work from home
  • Free transportation with DSB
  • Access to DSB's gym and PureGym
