Your mission

Your mission

NUNC Capital builds, acquires, and grows companies. We focus on groundbreaking defense and dual-use technologies. We do this independently and with a strategic horizon.

Since 2013, our international portfolio of companies has been growing. Every company in it deserves to operate safely, in an IT environment that keeps pace with tomorrow's ambitions and risks.

As IT Security Lead, you are responsible for the security and resilience of NUNC and all our portfolio companies. You won't be taking over an existing role, instead, you'll build and strengthen our security function from a position with a lot of freedom and responsibility. You'll work directly with our Tech Program Manager, our external IT partners, and the IT contacts at each portfolio company.

You have deep, up-to-date knowledge of the Microsoft security landscape and genuinely keep your market knowledge current. It's a plus if you can read and understand code, and test configurations yourself. Ensuring our security is fully in order at all times is simply non-negotiable for you.

You work in a project-based way: you implement and set up new tools and processes, always with an eye on efficiency and reducing dependency on external costs. We have an external partner for day-to-day support and management of our environment, but for new initiatives and strategic decisions, you're the one who drives this internally.

Specifically, you will be working on:

• Ownership of and continuous development of our Microsoft security stack and strategy
• Advising on and implementing security controls for applications and infrastructure, with a focus on Microsoft & Windows
• Designing, implementing, and optimizing security strategies
• Conducting and supporting information security risk analyses, including assessments of third parties regarding security and data privacy
• Identifying security gaps, translating risks into concrete technical solutions, and supporting their resolution
• Assessing and improving the effectiveness of technical and organizational security measures
• Advising teams on secure design principles, application integrity, and best practices within modern security architectures
• Running security and IT projects end-to-end, from scoping to implementation, with cost efficiency as a starting point
• Acting as a credible, technically knowledgeable conversation partner for senior developers and other MSPs, translating complex technical input into clear next steps
• Driving the continuous improvement process for ISO 27001 and leading the rollout of ABRO per project, providing security expertise currently lacking at the OpCo level
• Setting up proper data governance and documentation labeling (for example via Microsoft Purview), including the security dimension
• Contributing to innovation and new security propositions, including our approach to AI, with an eye toward a better user experience

Your profile

You make a difference with a strong, confident personality: you hold your own with demanding technical stakeholders and OpCos with outspoken opinions. You're analytically strong and quickly get to the core of things, even with complex technical issues.

You also have a proactive, forward-thinking mindset when it comes to security, and increasingly when it comes to AI as well. You're a credible conversation partner for senior developers and other MSPs, and you translate complex technical input into clear next steps with ease. You take initiative, work in a structured, project-based way, and feel comfortable in a role with a lot of responsibility and many stakeholders. You always keep cost efficiency sharply in view.

Requirements

• In-depth, practical knowledge of Microsoft security tooling (e.g., Defender, Entra ID, Purview, Intune, Sentinel)
• Experience with security strategy across multiple organizations or business units
• Experience with ISO 27001
• Fluent in both Dutch and English

Nice-to-haves

• Ability to read code yourself and test configurations
• Experience configuring within Linux and macOS environments
• Experience with frameworks such as ABRO

Why us?

What do we offer?

• A gross monthly salary of €5,000 to €6,000 (based on 40 hours)
• 8% holiday allowance
• 25 vacation days
• Pension plan via Allianz
• ClassPass subscription
• A prepared lunch daily
• Laptop and phone
• Training budget of €2,500 per year
